The APLT system self-weight can provide reaction force of 7 tons and can be increased to 15 tons to conduct tests using larger plates sizes.
The system is equipped with 6 to 30 in. diameter plates.
AASHTOWare™ Pavement ME Design guide uses resilient modulus (Mr) values in both rigid & flexible pavement design. The APLT system was designed to directly measure and develop the confining-stress-dependent Mr input values.
