The Comparison between Wheel Tracking and Triaxial Cyclic Compression Test on Different Asphalt Mixtures

Road structural materials should have satisfactory behaviour that enables a proper load carrying capacity. Asphalt mixtures used in road construction, must have properties that prevent formation of permanent deformations and cracking caused by temperature changes and fatigue. Road damages caused by the impact of different factors don't have equal impact on all sections of carriageway and have manifested in various forms. To determine resistance to permanent deformations at high temperatures of asphalt specimens, triaxial cyclic compression and wheel tracking tests are used. The authors have made wheel tracking tests according to standard SIST EN 12697-22and triaxial cyclic compression test according to standard SIST EN 12697-25 methodB. Experiments were done for all principal asphalt mixtures: AC, SMA, MA and PA to obtain an extensive model of asphalt behaviour for mixtures which contain the most and the least air voids. Mastic asphalt dictated the use of bitumen B20/30 in all mixtures with the intention to compare results of wheel tracking test and cyclic compression test for four asphalt mixtures. The cylindrical specimen in triaxial test is subjected to a confining stress and a cyclic axial stress at elevated conditioning temperature and vertical plastic deformation is measured. The results will be interpreted with a statistical model.
