摘要：

A type of styrene-butadiene-styrene (SBS) and crumb rubber (CR) composite modified asphalt (CMA) binder with a chemical (-C) method was proposed in this research. Dynamic shear rheometer (DSR) tests were conducted at different frequency and temperature to evaluate rheological properties of SBS/CR-C CMA in different aging conditions. Rheological master curves were also constructed to survey its rheological properties in a broad range of frequencies and temperatures. Based on test results, it was concluded that the rheology of SBS/CR-C CMA prepared by ultra-fine embedding grafting technology has been improved over a wide temperature range, showing good high and low temperature properties. In the low temperature domain, the asphalt provides good fatigue resistance attributed to the elastic property of CR. And in the high temperature domain, the copolymer network significantly improves the elastic response of SBS/CR-C CMA, showing better deformation recovery. In addition, short- and long-term aging enhance the shear deformation resistance and elastic behavior of SBS/CR-C CMA, but weaken the low temperature cracking and fatigue resistance performance. SBS/CR-C CMA has excellent anti-aging property. (C) 2019 Elsevier Ltd. All rights reserved.
