环氧沥青超薄罩面类型优化比选

OPTIMIZATION AND TYPE SELECTION OF SUPER-THIN EPOXY ASPHALT SURFACE

对环氧沥青超薄罩面类型进行优化比选,通过现场试验证明环氧沥青超薄罩面类型中,OGFC和SAC相关指标结果均满足规范与设计要求。比较2种类型的混合料,SAC的马歇尔试验、浸水马歇尔试验、车辙试验、抗滑试验和渗水试验的结果均明显优于OGFC,且SAC的综合效益显著高于OGFC,具有较好的路用性。

This paper analyzed the optimization and type selection of super-thin epoxy asphalt surface.Field test was carried out among different types of super-thin epoxy asphalt surface and test results showed that relevant parameters of OGFC and SAC satisfy the specification and design requirement.After comparison of mixtures in these two types,it was found that SAC has much better test result than OGFC on Marshall test,immersion Marshall test,wheel rutting test,anti-skid test and water seepage test.In addition,the general benefits of SAC is obviously better than OGFC,and it also has better applicability to road construction.
