Preparation and Study on the Rheological Behavior of Highly Viscous Rubber Modified Asphalt
摘要
Abstract
Drainage pavement is one of the effective methods to promote sustainable development and build sponge cities.This present study focuses on investigating high viscosity modified asphalt that is specifically designed for use in drainage asphalt pavement,using SBS particles and high viscosity rubber particles as the main components to modify the base asphalt.Through orthogonal experiments,the optimal dosage of high viscosity rubber modified asphalt was determined using 60 ℃ dynamic viscosity,softening point,needle penetration,ductility,elastic recovery,respectively.Selecting commonly used TPS modifier and XC modifier as the control group for comparative analysis,the bending beam rheological test(BBR)and dynamic shear rheological test(DSR)were used to analyze and evaluate the low-temperature crack resistance and high-temperature stability of three types of high viscosity asphalt.The results indicate that the high viscosity rubber modified asphalt prepared based on the optimal formula obtained from orthogonal experiments had excellent performance,providing a valuable reference for the development and application of high-viscosity modified asphalt in the field of road engineering.关键词
