Abstract

Abstract

The DCLR and TLA content are 5%, 10%, 15% and 20% by mass of SK-90 base asphalt respectively. The properties and microstructures of DCLR and TLA blending modified asphalts are tested by SHRP PG, penetration system, infrared spectrometer and gel permeation chromatograph. It indicates that adding DCLR and TLA can improve the high-temperature properties of asphalts, but the low-temperature and fatigue resistance of asphalts are declined. Based on the functional group and molecular weight distribution of asphalts, it predicts that the physical modification be happened in the DCLR and TLA blending modified asphalt. Meanwhile, the DCLR cannot replace TLA totally.
