高速公路沥青施工技术

Asphalt construction technology of expressway

结合某高速公路工程实例,从沥青混合料配置、拌合、摊铺、碾压几方面对某高速公路沥青路面施工技术进行探讨,分别通过沥青混合料拌制材料配合比与温度指标控制、沥青混合料摊铺厚度、速度控制与沥青混合料压实次数、转向角度等参数指标控制,在高速公路路面横向与纵向接缝处理后,施工质量得到有效控制,起到预期简化施工流程、提高施工效率、保障施工质量的效果。

In this paper,an example of a highway project is given,from the configuration,asphalt mixture mixing,paving and rolling of several aspects of the construction technology of the highway asphalt pavement are discussed,respectively,through the asphalt mixture mixing material mixing ratio and temperature control,the index of asphalt mixture paving thickness,speed control and asphalt mixture compaction times,steering angle parameter index,after the treatment of the transverse and longitudinal joints of the highway pavement,the quality of the construction has been effectively controlled,and the effect of simplifying the construction process,improving the construction efficiency and ensuring the quality of the construction is expected.
