RESEARCH ON TEMPERATURE MECHANICAL PROPERTIES OF GRANULATED CRUMB RUBBER ASPHALT MIXTURE

The papper does the research on the low temperature mechanical properties for asphalt rubber particles.The three indicators tensile strength,tensile strain,failure stiffness modulus rubber particles in experimental low-temperature splitting are used to evaluate asphalt mixture at low temperature mechanical properties.The experiments show that: the tensile strength,tensile strain and destruction of stiffness modulus greater rate of change of the three indices.indicating that the temperature in the low temperature mechanical material paragraph performance changes significantly.
