Abstract
Beneath every pavement are foundational layers of aggregate, soil, and other materials designed to suit the road’s location, traffic demands, and other factors. When roadway foundations are properly constructed, the finished pavement should perform well for decades. Until recently, however, inspection methods and tools have not been able to detect certain problems within the foundation until after the road is complete, making cracks and other premature distresses difficult to prevent. Through a demonstration project, Iowa DOT piloted innovative new technologies at several project sites that make it possible to assess and remediate issues during construction, leading to stronger foundations and better-performing pavements.
