Preparation and Performance Study of Directly-umped SBS Latex Modified Emulsified Asphalt
This paper investigates the effects of different types of latex on the performance of modified emulsified asphalt by directly adding SBS,SBR,and SBS/SBR mixed latex to emulsified asphalt to prepare modified emulsified asphalt.The penetration,softening point,ductility,storage stability,and high and low-temperature performance tests were conducted on the evaporative residues of modified emulsified asphalt with different latex contents.Considering the influence of three types of latex content on various properties of modified emulsified asphalt,the recommended contents are 6%for SBS latex,4%for SBR latex,and 6%for SBS/SBR mixed latex.
