THE CELERITY ANALYTICAL METHOD OF SBS MODIFIED BITUMEN

For modified bitumen of polymer, mechanism is a problem that should be studied firstly. This paper introduce modified bitumen present development, then analyses raw materials asphalt and modify pharmaceutical structure of SBS(Styrene-Butadiene-Styrene),the setting out inclusively of the pharmaceutical and bitumen from modifying, and following the concrete and overall analysis of the modified asphalt from dissolve bloated, absorb and from to modifying the impact on pitch performance to interface, space network structure according to the analysis to the celerity analytical method experimental result.
