This design pamphlet details suggested procedures to determine the design resilience modulus of subgrade soils in support of the 1993 AASHTO Guide for the Design of Pavement Structures. The design pamphlet includes recommendations of the subsurface characterization and exploration of subsurface soils, laboratory test procedures, and determination of design resilient modulus using relative damage coefficients based on a serviceability criteria and the damage coefficients to minimize permanent deformations in the subgrade.
