The Applied Research of Waste Crumb Rubber in Road Base

Abstract

Waste tiers increasing with geometric series, in view of that seeking a new treatment process has already become an urgent affair. Over the years, there has been mounting interest in the use of recycled tire rubbers in highway construction. Which have an important benefit to the recycling utilization of scrap tires and environmental protection, and can consume a large number of scrap tires. This paper presents an overview of some of the research published regarding the use of crumb rubber in highway engineering, but the study about the using of crumb rubber in cement-stabilized macadam base is seldom reported. This paper used ANSYS to build the pavement structure model, analyzed the effect to pavement by changing the thickness and modulus of cement stabilized macadam base with crumb rubber. It may serve as a useful reference for the future application of crumb rubber to the projects of cement-stabilized macadam base roads and other fields.
