Design Pamphlet for the Determination of Design Subgrade in Support of the 1993 AASHTO Guide for the Design of Pavement Structures
Primary Topic: Flexible Pavement
Description: Details recommended procedures to determine the design resilient modulus of subgrade soils. The design pamphlet includes recommendations for characterization and exploration of subsurface soils, laboratory test procedures, and determination of the design subgrade soil resilient modulus. Both the AASHTO Guide serviceability criteria and minimization of permanent deformation in the subgrade are considered. Other related pamphlets: FHWA-RD-97-076 & FHWA-RD-97-077.
