Xinjiang Region Road Rubber Asphalt Mixture Proportioning Design And Research

Rubber asphalt application at home and abroad has been a long time, is the matrix asphalt and rubber asphalt rubber powder combination according to certain proportion, add a variety of high polymer modifier,and swelling after fully with the matrix asphalt reaction at high temperature of the modified asphalt cement.Excellent performance of rubber asphalt mixture have been in the industry, but in the xinjiang region of rubber asphalt pavement structure and the choice of grading of the study also is less. This article from the perspective of rubber asphalt mixture proportioning design and research of rubber asphalt mixture road performance.First, reviewed the research data of rubber asphalt at home and abroad, to understand the basic performance of rubber asphalt and rubber asphalt mixture, and compared the basic standard of rubber asphalt mixture at home and abroad, based on the project to develop xinjiang region rubber asphalt mixture specification provides the basis.Second, on-the-spot investigation the grams of white road paving engineering and SMA layer above vomit a big child- happiness crossroads ganhe section of surface engineering, through the study of two different production process of rubber asphalt mixture ratio design, based on xinjiang highway project using rubber asphalt mixture proportion design.Finally, by G3012 aqaba highway paving test road 15 kilometers, mainly analyzes the high temperature stability of rubber asphalt mixture, low temperature crack resistance and durability.
