Along with the development of the cause of the traffic, the road of new material emergein endlessly, as a kind of new materials-reutilized vulcanized rubber modified asphaltmixture, it does not only make up the way of some shortcomings of building materials, and itis also a kind of energy conservation and environmental protection material. For thedevelopment of the cause of our country road opened up a new way. This article through tothe sulfur rubber modified asphalt mixture mechanical characteristics, this paper analyzes therubber modified asphalt mixture of mechanical properties of, the entity based on process, thepast construction stage, the shop is requiring attention matters.First of all, in order to get the waste rubber modified asphalt, and SBS modified asphaltmixture in different temperature damage mechanics strength, this paper in the samegradation and the shaping method to two hybrid materials mix proportion design, in the mixdesign of strict control on the strength of large effect on physical indicators, pore ratio, sothey can get the best comparative effect.Secondly, in the indoor on two of the asphalt mixture bend destructive test and mixtureof single axis of the static load test, in the mixture of bend destructive test, each kind ofspecimens in different temperature respectively, and that their deformation force and thecurve of the time, and the test conditions make two kinds of modified asphalt mixturebending of the evaluation of the performance. On rubber modified asphalt mixture and SBSmodified asphalt mixture for single axis static load strength test, to evaluate mixture in thesingle axis vertical load mechanics performance.Finally, this chapter with physical engineering to rely on, to study in this mix of rubbermodified asphalt mixture surfacing of matters requiring attention, this rely on engineeringChifeng in Inner Mongolia autonomous region, the big board for Chifeng highway, in thisproject, rubber asphalt mixture surfacing testing, as the research rubber modified asphaltmixture to provide the realistic basis.
