• Full thickness cold recycling subgrade materials were prepared by cement-emulsified asphalt solidified RAP and stabilized soil.The effect of adding amount of emulsified asphalts change on unconfined compressive strength, indirect tensile strength and water stability of cold recycled mixtures with different ratios was studied,and the mechanism of action of cement and emulsified asphalt in the mixtures was analysised via microscopic test. The results show that a proper addition of emulsified asphalt can improve the performance of cold recycled mixtures and the best emulsified asphalt mixing content is 3%. Microscopic test indicate that the cement hydration products space network structure interfinger with the emulsified asphalt network structure, so the cold recycled mixture tightly coupled to a semi-rigid whole, and the mixtures strength can form and develop.
