Conventional experiment methods of hot-mix asphalt mixture were adopted to do comparative analysis of initial stability, molding stability and residual stability with different cold patch additives. Marshall experimental method was adopted to do comparative analysis of physical index of cold patch asphalt mixture under five different gradations. Based on all above, researches have been done on the high and low temperature p
