The Current Using Situation of SBS Modified Asphalt in China and a New Method of Monitoring SBS Modifier Dosage

Article Preview

Abstract:

The relationship between the SBS modifier types and asphalt components on the effect of modified asphalt properties was discussed in this paper. Higher block ratio, higher molecular weight and star-like structure of SBS can improve modified asphalt high temperature properties. Colloid content decrease leading the processing easier, result stability decline. Our research group invented a chemical titration combined with fluorescence microscopic analysis detection method monitoring SBS modifier dosage. This method applied in highway construction site, the effect is significant.
