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.
