About Asphalt Paving
Asphalt paving is one of the most commonly used forms of construction today. This is due to its high adaptability and low cost. In addition, it is also considered to be a very practical option when it comes to home paving. However, it does have certain shortcomings that need to be taken note of. Read on to know about some of these and consider whether you should opt for asphalt or not.
One of the disadvantages of using an asphalt driveway is that it can be quite slippery. You need to make sure, therefore, that you drive your car carefully on it. And even if you do so, there is still a chance of your vehicle getting stuck on the asphalt. So, you should keep a good grip on the steering wheel and use all the available help you can. This is especially important if you are making a long distance drive.
There is also a possibility that asphalt might damage the surface underneath if it is not properly sealed. This is because asphalt is a petroleum product and petroleum products can cause damage to the environment. Therefore, you should make sure that the paved area is adequately sealed to make sure that it does not erode.
It is also important to remember that asphalt can crack when it gets too wet. If this happens, you will need to replace the area with new asphalt so that it does not get cracked again in future. Otherwise, you may end up spending more on repairing cracks that you have caused. In fact, asphalt cracks can be a real headache especially during heavy rains when the paver becomes very susceptible to water penetration.
Apart from this, asphalt is also susceptible to cracking when it is exposed to heat. This is especially true during summer months when the temperature is high. During this period, it is possible for the asphalt to get very soft and mushy. When this happens, it is much harder to seal the surface properly and repair any cracks that have developed.
Another problem that can occur with an asphalt paver is when it is being used improperly. For instance, when the asphalt paver is being used to pave driveways, it can easily grind over the edges of the driveway. The grout lines might also get damaged during this process. In fact, there are some homeowners who prefer using concrete or paved paths in front of their homes and driveways. However, they often forget that they should also seal these paths. Sealing the pathways will help to keep them protected from debris, grit, water and sand.
Homeowners should therefore find a qualified company to clean up their asphalt paver once in a while. These professionals will use a pressure washer to remove all the dirt and debris that have built up on the paver. They will then use a power washer to completely clean the water surface. After this is done, you can simply have the surfaces sealed and maintained by your local company.
By hiring a company to perform regular maintenance on your asphalt paver, you will be able to prevent some very common problems. For instance, if you find that the pavers have cracks, you can ask your local maintenance company to repair these cracks before they become larger. You can also ask them to apply new asphalt once a year. If you forget to do this, the asphalt will eventually wear out and begin to crack again. By properly maintaining your asphalt paver, you will be able to save yourself money in the long run because you will not have to call maintenance on a regular basis.
Commercial Paving and Maintenance Just as it’s important for homeowners to take care of their own personal landscaping, it’s just as important for commercial property owners to pay attention to how their pavements are maintained. Commercial Paving companies help commercial property owners keep their driveways and parking lots looking great, without spending more than they have to. However, commercial paving is not just about the look and feel of the pavement. It’s also about better traction and less maintenance. In fact, commercial asphalt pavements are among the most difficult to maintain in all kinds of weather conditions. Here are some common problems and solutions to avoid expensive maintenance dollars.
Most brick and stone pavements and slabs are fine in the rain, but they’re not so great when there’s heavy loads coming down. Asphalt and concrete are the most cost-efficient and durable materials for commercial paving projects, but there are now a wide range of choices, including brick-polishing, epoxy, permeable paving and composite pavers. Unlike traditional concrete and asphalt surfaces, permeable paver surfaces offer a porous surface to drain heavy loads and liquids, greatly eliminating the expensive and complicated drainage systems that are so often required… and of course, it’s maintenance free. Since permeable, commercial paving is available in a variety of colors and textures, it can also be a popular choice.
If your parking lot or driveway becomes flooded due to ice and snow, you may need to invest in a storm water detention system. Storm water detention systems are an effective way to control the runoff from storm water, which can cause damage to lawns, gardens and drives. A properly installed storm water detention system captures storm water runoff and re-circulates it away from your commercial property. In addition to reducing runoff and ensuring that it is safely discharged from your commercial property, a properly installed storm water detention system also reduces the risk of damage to your grass and flowers from run-off. And by re-circulating storm water, you can reduce the amount of time that water travels through your drains, which can reduce water damage to landscaping and your foundation.
For properties that already have a concrete surface, such as a parking lot, you may still want to consider the installation of additional drainage system. However, if you do not already have a concrete slab or parking lot, or if you are building a new structure, you may want to consider the installation of a permeable plastic pavement. In the past, these paved surfaces were reserved for very large commercial structures, but today they are becoming more common in residential areas as well. The primary reason for this is because permeable plastic pavers are more durable and require less maintenance.
Another benefit of a permeated parking lot or an asphalt surface is the fact that they are environmentally friendly. With asphalt, you have to use petroleum-based products to seal and repair damage, which is not only costly, but also adds to the damage that you have done to the earth. And while asphalt will not add any additional weight to your vehicle, there are reports that say that it can cause the vehicle to tip over. This is because when asphalt is filled with water, it can become compact and can squeeze the bumper of a vehicle.
Paved surfaces with permeable piers allow water to drain into a deeper spot, thus eliminating compacting issues and helping to keep vehicles from tipping over. Additionally, you can choose to have a seamless pavement, which can be installed in a variety of colors and materials. Concrete is also a popular paving material, but when you factor in the cost-effectiveness and the added maintenance required, asphalt really comes out on top.
Asphalt and paved areas are certainly attractive, but many people do not like the concrete appearance. The great thing about permeable plastic covers and gravel is that you can always choose something different to accentuate your landscape. Asphalt and concrete can both be dyed for various purposes, but gravel is a great alternative that does not require the extra investment and labor that other types of paving require.
When it comes to sealing and repairing damage on a commercial paving project, there is a tool that can help you out-prompt the process Sealcoating. It is important that you hire professional sealcoaters for your paving project to ensure that you get the job done correctly. By using a sealcoating product that is designed to work on wet, dry, and crack-free surfaces, you can seal and repair virtually any damage without having to replace the damaged pavement. There are many products available on the market that are specially formulated to work on all types of surfaces wet, dry, crack, and permeable. For more information about the sealcoating products that are available, contact a commercial paving services company.
About Oklahoma City, OK
Oklahoma City was settled on April 22, 1889, when the area known as the "Unassigned Lands" was opened for settlement in an event known as "The Land Run". Some 10,000 homesteaders settled the area that would become the capital of Oklahoma. The town grew quickly; the population doubled between 1890 and 1900. Early leaders of the development of the city included Anton Classen, John Shartel, Henry Overholser, and James W. Maney.
By the time Oklahoma was admitted to the Union in 1907, Oklahoma City had surpassed Guthrie, the territorial capital, as the new state's population center and commercial hub. Soon after, the capital was moved from Guthrie to Oklahoma City. Oklahoma City was a major stop on Route 66 during the early part of the 20th century; it was prominently mentioned in Bobby Troup's 1946 jazz song "(Get Your Kicks on) Route 66" made famous by artist Nat King Cole.
Before World War II, Oklahoma City developed major stockyards, attracting jobs and revenue formerly in Chicago and Omaha, Nebraska. With the 1928 discovery of oil within the city limits (including under the State Capitol), Oklahoma City became a major center of oil production. Post-war growth accompanied the construction of the Interstate Highway System, which made Oklahoma City a major interchange as the convergence of I-35, I-40, and I-44. It was also aided by the federal development of Tinker Air Force Base.
In 1950, the Census Bureau reported the city's population as 8.6% black and 90.7% white.
Patience Latting was elected Mayor of Oklahoma City in 1971, becoming the city's first female mayor. Latting was also the first woman to serve as mayor of a U.S. city with over 350,000 residents.
Like many other American cities, the center city population declined in the 1970s and 1980s as families followed newly constructed highways to move to newer housing in nearby suburbs. Urban renewal projects in the 1970s, including the Pei Plan, removed older structures but failed to spark much new development, leaving the city dotted with vacant lots used for parking. A notable exception was the city's construction of the Myriad Gardens and Crystal Bridge, a botanical garden and modernistic conservatory in the heart of downtown. Architecturally significant historic buildings lost to clearances were the Criterion Theater, the Baum Building, the Hales Building, and the Biltmore Hotel.
In 1993, the city passed a massive redevelopment package known as the Metropolitan Area Projects (MAPS), intended to rebuild the city's core with civic projects to establish more activities and life to downtown. The city added a new baseball park; a central library; renovations to the civic center, convention center, and fairgrounds; and a water canal in the Bricktown entertainment district. Water taxis transport passengers within the district, adding color and activity along the canal. MAPS has become one of the most successful public-private partnerships undertaken in the U.S., exceeding $3 billion in private investment as of 2010. As a result of MAPS, the population living in downtown housing has exponentially increased, together with the demand for additional residential and retail amenities, such as grocery, services, and shops.
Since the MAPS projects' completion, the downtown area has seen continued development. Several downtown buildings are undergoing renovation/restoration. Notable among these was the restoration of the Skirvin Hotel in 2007. The famed First National Center is being renovated.
Residents of Oklahoma City suffered substantial losses on April 19, 1995, when Timothy McVeigh detonated a bomb in front of the Murrah building. The building was destroyed (the remnants of which had to be imploded in a controlled demolition later that year), more than 100 nearby buildings suffered severe damage, and 168 people were killed. The site has been commemorated as the Oklahoma City National Memorial and Museum. Since its opening in 2000, over three million people have visited. Every year on April 19, survivors, families, and friends return to the memorial to read the names of each person lost. McVeigh was executed by lethal injection on June 11, 2001.
The "Core-to-Shore" project was created to relocate I-40 one mile (1.6 km) south and replace it with a boulevard to create a landscaped entrance to the city. This also allows the central portion of the city to expand south and connect with the shore of the Oklahoma River. Several elements of "Core to Shore" were included in the MAPS 3 proposal approved by voters in late 2009.
Oklahoma City lies along one of the primary corridors into Texas and Mexico, and is a three-hour drive from the Dallas-Fort Worth metroplex. The city is in the Frontier Country region in the center of the state, making it an ideal location for state government.
According to the United States Census Bureau, the city has a total area of 620.34 square miles (1,606.7 km), of which 601.11 square miles (1,556.9 km) is land and 19.23 square miles (49.8 km2) is water.
Oklahoma City lies in the Sandstone Hills region of Oklahoma, known for hills of 250 to 400 feet (80 to 120 m) and two species of oak: blackjack oak (Quercus marilandica) and post oak (Q. stellata). The northeastern part of the city and its eastern suburbs fall into an ecological region known as the Cross Timbers.
The city is roughly bisected by the North Canadian River (recently renamed the Oklahoma River inside city limits). The North Canadian once had sufficient flow to flood every year, wreaking destruction on surrounding areas, including the central business district and the original Oklahoma City Zoo. In the 1940s, a dam was built on the river to manage the flood control and reduce its level. In the 1990s, as part of the citywide revitalization project known as MAPS, the city built a series of low-water dams, returning water to the portion of the river flowing near downtown. The city has three large lakes: Lake Hefner and Lake Overholser, in the northwestern quarter of the city; and the largest, Lake Stanley Draper, in the city's sparsely populated far southeast portion.
The population density normally reported for Oklahoma City using the area of its city limits can be misleading. Its urbanized zone covers roughly 244 square miles (630 km) resulting in a 2013 estimated density of 2,500 per square mile (970/km2), compared with larger rural watershed areas incorporated by the city, which cover the remaining 377 sq mi (980 km) of the city limits.
Oklahoma City is one of the largest cities in the nation in compliance with the Clean Air Act.
Oklahoma City neighborhoods are extremely varied, with affluent historic neighborhoods located next to districts that have not wholly recovered from economic and social decline of the 1970s and 1980s.
The city is bisected geographically and culturally by the North Canadian River, which basically divides North Oklahoma City and South Oklahoma City. The north side is characterized by very diverse and fashionable urban neighborhoods near the city center and sprawling suburbs further north. South Oklahoma City is generally more blue collar working class and significantly more industrial, having grown up around the Stockyards and meat packing plants at the turn of the century, and is the center of the city's rapidly growing Latino community.
Downtown Oklahoma City, which has 7,600 residents, is seeing an influx of new private investment and large scale public works projects, which have helped to resuscitate a central business district left almost deserted by the Oil Bust of the early 1980s. The centerpiece of downtown is the newly renovated Crystal Bridge and Myriad Botanical Gardens, one of the few elements of the Pei Plan to be completed. In 2021 a massive new central park will link the gardens near the CBD and the new convention center to be built just south of it to the North Canadian River, as part of a massive works project known as "Core to Shore"; the new park is part of MAPS3, a collection of civic projects funded by a one-cent temporary (seven-year) sales tax increase.
Oklahoma City has a humid subtropical climate (Köppen: Cfa), featuring very hot, humid summers, and cool winters with occasional snowfall. Prolonged and severe droughts (sometimes leading to wildfires in the vicinity), as well as very heavy rainfall leading to flash flooding and flooding, occur with some regularity. Consistent winds, usually from the south or south-southeast during the summer, help temper the hotter weather. Consistent northerly winds during the winter can intensify cold periods. Severe ice storms and snowstorms happen sporadically during the winter.
The average temperature is 61.4 °F (16.3 °C), with the monthly daily average ranging from 39.2 °F (4.0 °C) in January to 83.0 °F (28.3 °C) in July. Extremes range from −17 °F (−27 °C) on February 12, 1899 to 113 °F (45 °C) on August 11, 1936, and August 3, 2012; the last sub-zero (Fahrenheit) reading was −14 °F (−26 °C) on February 16, 2021. Temperatures reach 100 °F (38 °C) on 10.4 days of the year, 90 °F (32 °C) on nearly 70 days, and fail to rise above freezing on 8.3 days. The city receives about 35.9 inches (91.2 cm) of precipitation annually, of which 8.6 inches (21.8 cm) is snow.
The report "Regional Climate Trends and Scenarios for the U.S. National Climate Assessment" (NCA) from 2013 by NOAA, projects that parts of the Great Plains region can expect up to 30% (high emissions scenario based on CMIP3 and NARCCAP models) increase in extreme precipitation days by mid-century. This definition is based on days receiving more than one inch of rainfall.
Oklahoma City has an active severe weather season from March through June, especially during April and May. Being in the center of what is colloquially referred to as Tornado Alley, it is prone to especially frequent and severe tornadoes, as well as severe hailstorms and occasional derechoes. Tornadoes have occurred in every month of the year and a secondary smaller peak also occurs during autumn, especially October. The Oklahoma City metropolitan area is one of the most tornado-prone major cities in the world, with about 150 tornadoes striking within the city limits since 1890. Since the time weather records have been kept, Oklahoma City has been struck by 13 violent tornadoes, eleven rated F/EF4 and two rated F/EF5.
On May 3, 1999, parts of Oklahoma City and surrounding communities were impacted by a tornado. It was the last U.S. tornado to be given a rating of F5 on the Fujita scale before the Enhanced Fujita scale replaced it in 2007. While the tornado was in the vicinity of Bridge Creek to the southwest, wind speeds of 318 mph (510 km/h) were estimated by a mobile Doppler radar, the highest wind speeds ever recorded on Earth. A second top-of-the-scale tornado occurred on May 20, 2013; South Oklahoma City, along with Newcastle and Moore, was hit by an EF5 tornado. The tornado was 0.5 to 1.3 miles (0.80 to 2.09 km) wide and killed 23 people. On May 31, less than two weeks after the May 20 event, another outbreak affected the Oklahoma City area. Within Oklahoma City, the system spawned an EF1 and an EF0 tornado, and in El Reno to the west, an EF3 tornado occurred. This lattermost tornado, which was heading in the direction of Oklahoma City before it dissipated, had a width of 2.6 miles (4.2 km), making it the widest tornado ever recorded. Additionally, winds in excess of 295 mph (475 km/h) were measured, one of the two highest wind records for a tornado.
With 19.48 inches (495 mm) of rainfall, May 2015 was by far Oklahoma City's record-wettest month since record-keeping began in 1890. Across Oklahoma and Texas generally, there was a record flooding in the latter part of the month.
According to the 2020 census, the racial composition of Oklahoma City was as follows:
As of the 2010 census, there were 579,999 people, 230,233 households, and 144,120 families residing in the city. The population density was 956.4 inhabitants per square mile (321.9/km). There were 256,930 housing units at an average density of 375.9 per square mile (145.1/km2).
Of Oklahoma City's 579,999 people, 44,541 reside in Canadian County, 63,723 reside in Cleveland County, 471,671 reside in Oklahoma County, and 64 reside in Pottawatomie County.
There were 230,233 households, 29.4% of which had children under the age of 18 living with them, 43.4% were married couples living together, 13.9% had a female householder with no husband present, and 37.4% were non-families. One person households account for 30.5% of all households, and 8.7% of all households had someone living alone who was 65 years of age or older. The average household size was 2.47 and the average family size was 3.11.
The median income for a household in the city was $48,557 and the median income for a family was $62,527. The per capita income for the city was $26,208. 17.1% of the population and 12.4% of families were below the poverty line. Out of the total population, 23.0% of those under the age of 18 and 9.2% of those 65 and older were living below the poverty line.
In the 2000 Census, Oklahoma City's age composition was 25.5% under the age of 18, 10.7% from 18 to 24, 30.8% from 25 to 44, 21.5% from 45 to 64, and 11.5% who were 65 years of age or older. The median age was 34 years. For every 100 females, there were 95.6 males. For every 100 females age 18 and over, there were 92.7 males.
Oklahoma City has experienced significant population increases since the late 1990s. Since the official Census in 2000, Oklahoma City has grown 25 percent (a 125,214 raw increase) according to the Bureau estimates. The 2016 estimate of 638,367 is the largest population Oklahoma City has ever recorded. It is the first city in the state to record a population greater than 600,000 residents. It is also the first city in the Great Plains region to record a population greater than 600,000 residents. It is the largest municipal population of the Great Plains region (Oklahoma, Kansas, Nebraska, South Dakota, North Dakota).
Oklahoma City is the principal city of the eight-county Oklahoma City Metropolitan Statistical Area in Central Oklahoma and is the state's largest urbanized area. As of 2015, the metropolitan area was the 41st largest in the nation based on population.
Law enforcement claims Oklahoma City has traditionally been the territory of the notorious Juárez Cartel, but the Sinaloa Cartel has been reported as trying to establish a foothold in Oklahoma City. There are many rival gangs in Oklahoma City, one whose headquarters has been established in the city, the Southside Locos, traditionally known as Sureños.
Oklahoma City also has its share of violent crimes, particularly in the 1970s. The worst occurred in 1978, when six employees of a Sirloin Stockade restaurant on the city's south side were murdered execution-style in the restaurant's freezer. An intensive investigation followed, and the three individuals involved, who also killed three others in Purcell, Oklahoma, were identified. One, Harold Stafford, died in a motorcycle accident in Tulsa not long after the restaurant murders. Another, Verna Stafford, was sentenced to life without parole after being granted a new trial after she had been sentenced to death. Roger Dale Stafford, considered the mastermind of the murder spree, was executed by lethal injection at the Oklahoma State Penitentiary in 1995.
The Oklahoma City Police Department has a uniformed force of 1,169 officers and 300+ civilian employees. The department has a central police station and five substations covering 2,500 police reporting districts that average 1/4 square mile in size.
On April 19, 1995, the Alfred P. Murrah Federal Building was destroyed by a fertilizer bomb manufactured and detonated by Timothy McVeigh. The blast and catastrophic collapse killed 168 people and injured over 680. The blast shock-wave destroyed or damaged 324 buildings within a 340-meter radius, destroyed or burned 86 cars, and shattered glass in 258 nearby buildings, causing at least an estimated $652 million worth of damage. McVeigh was convicted and subsequently executed by lethal injection on June 11, 2001.
