Series of Thermal Stress Restrained Specimen Tests (TSRST) on bituminous mixtures have been carried out and analyzed at the Civil Engineering Department (DGCB) of ENTPE. In order to realize such test, which imply a thermo-mechanical coupling, an experimental device has been especially designed and developed at ENTPE. Two sensors were added to measure the acoustic emission during the test. Such sensors are used to listen to the micro-cracks which develop along TSRS tests test and direct tensile tests are presented. The results of acoustics emission measurements are also analyzed.
