This document describes a procedure for verifying a dynamic testing system (closed-loop servohydraulic). 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. This procedure may be used to evaluate a wide range of equipment and has applications to many test procedures. Implementation of this procedure in the Federal Highway Administration contractor laboratories has greatly reduced the within- and between-lab variability associated with the Long-Term Pavement Performance resilient modulus test procedures.
