Abstract
During winter conditions, low-temperature cracks develop at the surface of the asphalt pavement when tensile thermal stress induced in the asphalt layer during cooling equals and exceeds the tensile strength of the material. The paper presents the results of tensile strength reserve assessment of asphalt mixtures with neat and SBS-polymer modified bitumen application. The tensile strength reservewas calculated as difference between the tensile strength βt(T) obtained from the uniaxial tension stress test (UTST) and the cryogenic (thermal) stress σcry(T) obtained from the thermal stress restrained specimen test (TSRST) at the same temperature T. It can be useful factor assessing the low-temperature properties of asphalt mixtures. It was found that the highest values of tensile strength reserve were obtained for the asphalt mixture with SBS-polymer modified bitumen.
