Full-Scale Aggregate Base Design and Construction

This activity is aligned with the International Center for Aggregates Research and National Stone, Sand, and Gravel Association research priority list. The activity addresses the issue of using higher modulus, more dense bases construction for thinner asphalt concrete layers, thereby saving agencies money. This activity began to explore methods, which advance the state of the practice in granular base construction, material selection/specification, recycling and blending, and performance modeling. It has evolved with many attributes. Three main aspects are: Alternative construction techniques; Pavement design structural configuration; and Improved materials characterization and modeling. Validation of the International Center for Aggregate Research cross-anisotropic resilient modulus material model for use in design and contributions to performance prediction is key.
