About the research

Abstract:

A continuing challenge to the concrete paving industry is the ever present need to implement new technologies as they are proven, coupled with the need to educate new employees throughout the industry about best practices. The object of this project is to help meet this need by conducting technology transfer, delivery, and implementation of best practices for jointed concrete pavements. Activities are focused on these topics:
