Assessing asphalt integrity

摘要

Properly compacted asphalt is a major factor in the lifespan of a road, as inadequately compacted asphalt deteriorates at a more rapid rate than properly compacted material. With the billions spent on road construction and repairs each year, it has become a matter of urgency to find new technologies that can ensure the integrity of asphalt on newly paved roads. New radio wave technology is now available to nondestructively determine asphalt density during application.
