Resilient Modulus Test System

What is the Resilient Modulus test?

Resilient Modulus Data Sheet

Sample Geotechnical Report

LoadTrac II-RM

Geocomp's LoadTrac II Resilient Modulus unit fully automates resilient modulus tests on base/subbase/subgrade materials. The LoadTrac II meets or exceeds all specifications for Resilient Modulus Testing of Base/Subbase/Subgrade Materials by AASHTO T 294/T 307, SHRP Protocol P46, and NCHRP RPT 285. It generates a complete final test report with graphs and table values as well as constitutive realtionships based on publication No. FHWA-RD-97-083. It minimizes man time during testing and offers a versatile platform for performing additional geotechnical tests.

Applicable Test Standards

AASHTO T 294, T 307
