摘要
Abstract
In response to the common problem of cracking in cement-stabilized crushed stone(CSB)base materials,which leads to surface cracking in pavements,this study conducts mechanical and shrinkage tests on ordinary cement stabilized crushed stone materials by adding waste rubber powder and fiber materials.Test results showed that the addition of waste rubber powder alone significantly reduced the load-bearing capacity and flexural strength of the cement-stabilized crushed stone,with a performance decline of approximately 10%～30%at the same curing age.The incorporation of fibers not only offset the negative effects of waste rubber powder but also resulted in a 10%improvement in mechanical performance compared to the control group.Waste rubber powder significantly improved the shrinkage resistance of the CSB,while the addition of fibers had little effect on improving shrinkage performance.Therefore,the simultaneous addition of both fibers and waste rubber powder can effectively enhance both the mechanical and shrinkage performance of cement-stabilized crushed stone materials.关键词
