Abstract
An instrumented asphalt pavement was built at the INDOT/Purdue accelerated pavement testing facility. The construction processes induced preferred aggregate orientation and lock-in of horizontal stresses, resulting in mechanical anisotropy. This anisotropy is investigated by means of inverse analysis. The pavement system is modeled as a linear elastic transversely-isotropic layered halfspace; anisotropic properties are back-calculated using the time history of all embedded gauge readings, collected during one load pass. The experiment and analysis method are presented; results are compared with the isotropic case and discussed.
