Asphalt is safe, economical, and it is the most long-lasting and durable paving material. In addition, asphalt pavement is 100% recyclable. Of the 2.27 million miles of paved road in the US, 94% is surfaced with asphalt, including 65% of the interstate system. Asphalt pavements provide the user with a smooth, quiet, safe ride surface. A smooth pavement saves wear and tear on vehicles. Properly designed, built and maintained asphalt pavements enhance vehicle safety by providing a renewable, skid-resistant surface. A smooth surface maximizes tire contact, increasing skid resistance.
