Vehicles use less fuel when traveling on smoother asphalt pavement roads.
Pavement smoothness directly affects vehicle fuel economy. The smoother the pavement, the higher the rate of fuel economy a vehicle will have traveling on that road. Our country has over 2.5 million miles of paved roadways. If every American saved a few MPG per year, that would dramatically cut overall fuel consumption in the U.S. This would help conserve our natural resources and save millions of dollars spent on fuel.
Asphalt roads are smoother than concrete.
Each state has different standards for newly built roads. Some state’s standards are different for asphalt and concrete construction. The standards for asphalt roads are more stringent than for concrete roads.
Constructing smooth and Resurfacing smoother asphalt paved roads
Once a well-engineered foundation is set for an asphalt roadway it can be constructed and will last virtually indefinitely. Routine maintenance such as pothole repairs and crack repairs can be made as needed. After a period of about 15-20 years the asphalt pavement will need to be milled. Milling is the process of shaving the top layer of pavement. This worn asphalt can be rejuvenated and reused on-site during demolition and construction. A fresh layer of asphalt called an asphalt overlay can then be installed. Resurfacing an asphalt paved roadway will perform just as good as new.
