Research on the Performance of Emulsified-Asphalt Recycled Mixture–Based Cement Dosing.

In order to solve the problem of semirigid base damage in the initial period of use, this paper focused on emulsified-asphalt cold recycled mixtures with all old mineral and analyzed its strength formation mechanism. The optimum moisture content and amount of emulsified asphalt in the regenerated base were determined through tests, whereas the performance of the mixtures was verified according to the designed optimum ratio. The gray correlation method was used to analyze the performance-influencing factors and determine the rationality of the base designs. The research results can be used for pavement base recycling with a new solution for old roads, and the efficiency of pavement construction was greatly improved. It also reduced the heat and energy loss and contributed to the sustainable environmentally development of road construction. [ABSTRACT FROM AUTHOR]
