ASPHALT PAVEMENT

There is approximately 18 billion tons of asphalt pavement on America’s roads. Asphalt is the most cost-effective way to build and pave roads, both in the actual material and the cost of traffic delays. Asphalt pavements were always durable, but technology has created pavement structures that, for practical purposes, last forever.
