Experimental Study On The Performance Bituminous For Crumb Rubber Composite Modified Asphalt

With the gradual recovery of the global economy, each countries`s car production and sales are rising constantly, it also brought great many countries, economic benefits, but followed a more serious problem is the disposal of waste tires the same time, some countries this problem has become not a small effect early, so high priority on green energy today, all countries have to deal with the problem of waste tires have been classified as related to people's livelihood, environmental protection event.In recent years, countries in many areas began to study researchers have started on the treatment and use of discarded tires are from a different perspective in the study if the waste tire recycling Po. Road sector research also found that the processed waste tires and the asphalt are fused in some way better performance can be asphalt, called the modified asphalt. Such modified asphalt and asphalt to improve its high stability, water stability, low temperature crack resistance and other properties of great help. This article continues the research perspective, in the original study based on the asphalt and draws on highway and Hunan Hunan Heng Yan Ji Chang advanced experience of the highway, through the waste tire rubber powder + Domix dual compound modified asphalt related research to further improve itself and its mixture of asphalt pavement performance, including high temperature stability, water stability and other properties.In this paper, the successful experience of the relevant reference works, through the incorporation Domix to further research related to performance and with the crumb rubber modified asphalt and SBS modified bitumen compared to experiment to find one of the advantages and disadvantages, and such modified asphalt material can further be widely used on the project to lay a solid theoretical basis.
