LTPP Materials Characterization Program: Resilient Modulus of Unbound Materials (LTPP Protocol P46) Laboratory Startup and Quality Control Procedures

General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Materials-Unbound and Soils

Description: This document describes a procedure for resilient modulus quality control checks. The procedure evaluates the ability of laboratory personnel and the test system to complete LTPP P46 protocol for resilient modulus testing. The procedure is divided into three general phases: (1) Electronic System Performance Verification, (2) Calibration Check and Overall System Performance Verification, and (3) Proficiency Testing. The implementation of this procedure in the FHWA Contractor Laboratories has greatly reduced the within and between-lab variability associated with the LTPP P46 test procedure.
