摘要
对比分析了两种不同级配类型的混合料(AC-13、SMA-13)作罩面时的路用性能,结果表明薄层罩面是一种高性能的养护措施,其与原路面结合性较好,但不同级配类型的混合料罩面效果差别较大,在进行罩面设计时应选择合适的级配类型,并在施工时严格控制孔隙率。
The paper comparatively analyzes pavement performance through two different gradation types mixture（AC-13,SMA-13）,the result shows that the thin-layer overlay is a conservation measure of high performance,and combines well with the original road,but the effect of mixture overlay of different types gradation varies greatly.During designing the overlay,appropriate gradation type should be selected,and porosity should be controlled strictly in the construction.
