STRUCTURAL AND RHEOLOGICAL PROPERTIES OF BITUMEN ACCORDING TO THE RANGE DETERMINED BY TEMPERATURE

PROPRIETES STRUCTURALES ET RHEOLOGIQUES DES ASPHALTES DANS DES GAMMES DETERMINEES DE TEMPERATURE

To estimate the quality of road asphalt it is necessary to conduct investigations at temperatures below freezing when the asphalt loses its plastic characteristics and at high temperatures when it forms a non-Newtonian fluid. This report gives the quality coefficients of asphalts at temperatures below freezing: modulus of elasticity, resistance and limit deformation depending on temperature, structural viscosity and the surface of viscosity hysteresis. It has been established that the parameters depend on the group composition and the chemical character of asphalt. (TRRL)
