Publication details: Washington DC Strategic Highway Research Program, 1994; SHRP-P-693, Subject(s): Online resources: Bibl.nr: VTI P1411:693Location: Abstract: This research also used SHRP Protocol 46, "Resilient Modulus of Unbound Granular Base/Subbase Materials and Subgrade Soils" (see description, SHRP-P-692), and was conducted for the same reasons as described in the abstract for SHRP-P-690. A set of three synthetic reference samples was acquired, and instructions for testing were prepared. The set was circulated to 14 participating laboratories for testing. Worksheets, supporting data, analyses, final comments, and conclusions are presented. A complete set of proficiency sample statements in American Association of State Highway and Transportation Officials/American Society for Testing and Materials format is provided.This research also used SHRP Protocol 46, "Resilient Modulus of Unbound Granular Base/Subbase Materials and Subgrade Soils" (see description, SHRP-P-692), and was conducted for the same reasons as described in the abstract for SHRP-P-690.
