Research on the Performance of Regenerant Modified Cold Recycled Mixture with Asphalt Emulsions

In order to study the mechanical properties and effect of a regenerant on cold recycled mixture with asphalt emulsions (CRMEs), moisture susceptibility, high-temperature performance, low-temperature dynamic durability CRMEs were analyzed evaluated by immersion splitting strength tests, freeze-thaw rutting semi-circle bending uniaxial compression modulus tests indirect tensile tests. Scanning electron microscopy (SEM) was used analyze micromorphology modified regenerant. Finally, comprehensive evaluation system five different established based efficacy coefficient method quantitatively performance CRMEs. The test results showed that can significantly improve water strength, fracture energy density, fatigue resistance However, addition affected mixture. first increased then decreased content increasing. When 8%, highest. Adding styrene-butadiene rubber (SBR) latex CRMEs, but low temperature not improved, reduced. Based method, optimal is 8%. Regenerant are potential modifiers for they durability.
