| 摘 要： | 高速公路服务区路面频繁受到车辆施加的水平力的作用,超薄水泥混凝土(UTW)路面抗水平力破坏性能强,但将UTW用于服务区新建路面需要有针对性地进行路面设计.在分析服务区交通特性和UTW受力特性的基础上修正了轴载等效换算公式；引入超细粉煤灰(UFA)等量取代部分水泥,设计出的UTW板水泥混凝土满足结构要求；通过直接剪切试验... |

| Abstract: | The pavement of expressway service area is subjected to horizontal force from vehicles frequently.Moreover Ultra-thin whitetopping(UTW) can resist the horizontal force.However,special design must be made for UTW pavement in expressway service area.The traffic characteristics of expressway service area and mechanical performance of UTW pavement were analysed.Based on these,axle load equivalent conversion formula was amended.Ultra-fine fly-ash(UFA) was used to replace the same amount of cement of UTW cement c... |
