The proposed research initiative consists of on-site and laboratory tests to evaluate the compaction quality of road sub-soils. To that end, we will use a self-boring pressure-meter to determine the on-site resilient modulus and compare it with results obtained by the Quebec transportation department using triaxial equipment for deviatoric loading in accordance with the LC-22-400 method. Studies demonstrate that the resilient modulus is an essential parameter for road design and analysis.
