Development of a GPC Chromatograms Decomposition Method for Identifying and Quantifying the Degradation of SBS Polymer Modified Bitumen

SBS polymer modified bitumen (SPMB) can notably improve the performance of asphalt pavement and is widely employed on the surface layer of pavements. However, SBS polymer is sensitive to ageing and its degradation evolution is difficult to be quantitatively characterized due to the overlapping of GPC chromatograms. In this research, a...
