Effects Of Different High Modulus Admixture Of Asphalt Road Performance

Since the twentieth century,China of rapid economic development,logistics and express began to rise.China’s vehicles show explosive growth.With the rise of the transport industry,vehicle overload heavy load more and more serious damage to the road structure,many large areas of road rut disease.And thus caused a rapid decline in the level of road services.With the development of science and technology,people began to use the newly developed road materials in the new road,including high modulus admixture,high modulus admixture can improve the asphalt mixture resistance to high temperature rutting ability,can effectively extend the road The number of years to reduce the number of road renovation and maintenance.In order to reveal the phase composition of high modulus admixture and better understand the principle of high modulus admixture,the heat flux curve and heat flux value of four kinds of high modulus outer admixture were measured by thermal difference scanning(DSC).Based on the absorption of heat in the process of phase transition,the process of phase change with temperature is analyzed,and the temperature sensitivity of high modulus admixture is more fully understood.Understanding the Working Mechanism of High Modulus Admixture from MicrocosmicThe high modulus asphalt mixture was prepared by adding asphalt high modulus admixture.The ratio of the admixture and the ratio of the high modulus asphalt mixture were determined.The rutting test,the elastic modulus test and the splitting Test,bending test and other tests of its high and low temperature performance and mechanical properties.And the results of DSC test were used to verify the road energy of high modulus asphalt mixture.
