Abstract: This article simulated three mortar systems including mineral filler⁃asphalt,mineral filler⁃emulsified asphalt residue and cement⁃emulsified asphalt residue in cold recycled mixture with emulsified asphalt. The results show that cement⁃emulsified asphalt residue mortar owns higher modulus than the other two mortars because of cement hydration. The change of modulus and phase angle is different from that of ordinary mineral powder⁃asphalt mortar and mineral powder⁃emulsified asphalt mortar, and does not change linearly monotonously with powder⁃to⁃binder ratio. At the same time, the interface adhesive ability of cement⁃ emulsified asphalt residue is similar to that of the mineral filler⁃asphalt mortar, and much higher than that of the mineral filler⁃emulsified asphalt residue mortar in a lower filler dosage. In the process of mixture production, emulsified asphalt provides the initial stability of the mixture, and cement hydration and the formation of composite mortar system are the guarantee of the final cold recycled mixture strength.

摘要： 对乳化沥青冷再生混合料中的三种胶浆系统进行了研究，包括沥青+矿粉、乳化沥青残留物+矿粉和乳化沥青残留物+水泥。结果表明，因为水泥水化作用的存在，水泥⁃乳化沥青残留物胶浆表现出更高的模量增率效果；模量和相位角变化呈现与普通矿粉⁃沥青胶浆和矿粉⁃乳化沥青胶浆不同的特点，且不随粉胶比呈现线性单调的变化；胶浆界面黏结力与矿粉⁃沥青胶浆相当，并在低粉胶比范围内远高于单独利用矿粉的乳化沥青残留物胶浆。
