Colored Pavement Material Properties And Construction Technology Research

This thesis studies on the performance of the color asphalt mixture and color cement slurry-filling asphalt mixture.The color asphalt mixture is a kind of mixture whose binder is used a special color binder instead of the common asphalt and the color binder is polymerized by resin, polymer and other additional agents. The thesis introduces manufacture technology of the color binder. The three series of color binder developed by ourselves have superior performance than the same type products in the world. According to Marshall design method, the performances of the mixtures with six-graded color binder and ESSO asphalt are studied and the results show that the performance of resistance to rutting at high temperature, water stability, resistance to crack at low temperature and resistance to fatigue of color asphalt mixture is the same as or superior to the common asphalt mixture.Color cement slurry-filling asphalt mixture is a new kind of mixture formed by filling special cement slurry into asphalt mixture with large void and open grade. On the basis of researches inside and outside of the country, this thesis studies the mix of color cement slurry, gives a simple design method of carrier asphalt mixture. The pavement performance of color cement slurry-filling asphalt mixture is also researched that it has excellent high temperature stability, water stability, and resistance to fatigue and certain resistance to crack at low temperature.Finally, the construction technique of color pavement is studied.
