Pavement Design: Performance of Base versus Subbase

Status:  Active
Project Start Date:  06/14/2023


This work will consider material availability, load characteristics and quality indicators for performance of base and subbase materials. This project will provide guidance both to designers/practitioners to use key aggregate resources and to local agencies for evaluating locally available materials for designing cost-effective flexible and rigid pavements.The project will explore aggregate/pavement layer characteristics that should be evaluated, and determine when/how a thicker subbase and a thinner base is constructed.
