Snow/ice Self-melting pavement is a new kind of pavement with asphalt mixtures containing anti-freeze additives.In this research,three kinds of anti-freeze additives(IB-A,IB-B and IB-C)were applied.IB-A is a chloride salt that contains four substances and IB-B is a sulfonate including two substances.IB-C is a kind of Phase change material.The performance of asphalt mixtures were evaluated by using a series of laboratory tests,such as high temperature resistance,low temperature crack resistance and moisture resistance.Furthermore,based on the surface contact mechanism relationship between ice and pavement surface,a test instrument was developed and a new method was proposed to evaluate snow/ice melting efficiency.The test results show that the asphalt mixture with IB-A has the highest snow/ice melting efficiency and IB-C has no difference with the control group.To balance the performance and snow/ice melting efficiency,the optimum anti-freeze filler content were determined and proposed to apply in the zhangcheng highway pavement de-icing engineering.
