Influence of microcapsules on rheological properties of asphalt mortar

In order to study the effect of microcapsules on rheological properties asphalt mortar, were prepared by interfacial polymerization and mixed with 70# matrix SBS modified in different proportions prepare two kinds microcapsule mortars. The mortar measured dynamic shear experiment curved beam experiment. test results show that method have a smooth surface, high coating rate, an average particle size about 14.3μm; temperature properties, rutting factor mortars showed varying degrees reduction increase content. When content is greater than 0.6%, do not change significantly; low creep stiffness modulus S gradually decreases content, rate m increases
