TechBrief: Improving Accuracy of Unbound Resilient Modulus Testing
Primary Topic: Pavement Maintenance
Description: A quality control/quality assurance (QC/QA) procedure has been developed for resilient modulus of soil and aggregate materials. This procedure can be used to achieve repeatable, reliable, high-quality resilient modulus data for soil and aggregate pavement materials. As evidenced from implementation in the Long-Term Pavement Performance (LTPP) program, it is a highly effective tool to reduce the historically large within- and between-laboratory variability associated with this test procedure.
