Popis: Causes of aggregate fretting of porous asphalt pavements are classified in two categories. The first category is due to the application of impact load on the brittle condition of binder at low temperature. The second category is due to the application of torsion and/or horizontal shear load on the low consistency of binder at high temperature. We conducted three types of laboratory experiment by changing binder type and air void content. Adapted three types of test method are Cantabro test, repeated torsional load test and direct shear test considering impact load, torsional load and shear load respectively. Test results showed that binder type and air void content had great influence on aggregate fretting resistance of porous asphalt mixtures .
