Which material is better for paving, asphalt or concrete? This debate has gone on for years. Asphalt is a compound of a hydrocarbon and other materials. The hydrocarbon used comes from crude oil, and it is heated until is looks like tar. Next, the tar-looking material is mixed with stones, gravel, and sand to make asphalt. It has been used since the 1920’s to cover highways, bridges, and driveways. There are those who prefer asphalt because it leaves a very smooth surface. As a result, it does not produce a lot of traffic noise.
Asphalt Paving Contractors, like Goode Paving & Sealcoating Inc., know that asphalt is easy to repair and maintain. Further, asphalt is less expensive than other materials. On the other hand, critics say asphalt is not as strong as other surfaces. For example, concrete lasts longer, but it is a more expensive paving choice. Concrete is a mixture of broken rocks, water, and cement. It is primarily used on local roads and small projects like parking lots. One of the concrete’s negatives is its rigidness. The material is likely to crack in extreme temperatures.
Asphalt highways have many advantages over concrete. Asphalt Paving Contractors in Bel Air, MD know that asphalt performs better in areas that get lots of ice and snow. For instance, ice takes longer to melt on concrete than on asphalt. Further, tires have better traction on asphalt roads in all types of weather. It appears that asphalt roads will remain the industry standard. Cost is always the bottom line, and asphalt is cheaper. Governments can pave more roads with less money. Also, lawmakers do not like traffic disruptions due to highway repairs. Fortunately, asphalt repairs can be made quickly.
Industry insiders advertise asphalt as a green product. Indeed, it is an example of durability and sustainability in one product. The EPA says 80-million tons of asphalt pavement are reclaimed every year. Amazingly, reclaimed asphalt is made into a product that is better than the original. Moreover, the same asphalt can be recycled indefinitely. Other materials like asphalt shingles are melted down and mixed with asphalt. This practice saves thousands of acres of landfill space. Further, recycling asphalt saves taxpayers millions every year.
