Analysis on the Key Points of SMA Mix Design for Expressways in Different Provinces and Autonomous Regions
摘要
Abstract
Through investigation and comparison of key raw material indicators such as aggregate,fiber,modified asphalt,anti-stripping agent,etc.,which are commonly used in the upper layer of expressways in nine provinces and autono-mous regions,and based on the characteristics of raw materials of asphalt mixture for the upper layer of expressways in the above areas,taking the SMA-13 as an example,the key points of mix design are analyzed,and some suggestions are put for-ward for the selection of raw materials,bitumen aggregate ratio,anti-stripping agent,and the guarantee of water stability,high temperature stability,skid resistance,which can provide reference for the design and construction of expressway pavement.关键词
