Comparative Seismic Laboratory and Non-Contact Field Measurements of Asphalt Concrete
Non-contact acoustic field measurements are performed on a newly built highway to characterize the real part of the dynamic modulus of the asphalt concrete (AC) top layer. The in situ measurements are performed using an array of 48 micro-electromechanical system (MEMS) sensors. Cores extracted from the field measurement positions are then examined in a laboratory using seismic modal testing for co
