Abstract


Cationic emulsified asphalt road construction , a pavement material conservation , environmentally-friendly and energy-efficient method of mixing cement emulsified asphalt concrete highways researchers at home and abroad , and to improve the performance of this material . Basically be able to reach the ordinary asphalt concrete pavement performance indicators , but also save uniformity , bond strength and durability , the road surface flatness of the concrete material inadequacies . This paper is add hydrated lime to improve the inadequacies of the original cement emulsified asphalt concrete , and enhance the bond strength between the asphalt and aggregate to improve its durability , the formation of a variety of binder cold shop composite bonding material asphalt concrete . First discuss the experimental method suitable for cold shop composite asphalt concrete material performance characteristics , and recommended testing methods and the order of addition of the the mix further amended Marshall experiments , and then through the experiment , the cold shop composite asphalt concrete mixture ratio and adding a certain percentage hydrated lime concrete road performance , the final analysis the cold paving the construction process of the composite asphalt concrete pavement materials and methods , as well as economic and technical analysis and evaluation of .
