城市道路沥青路面质量控制探讨

城市道路沥青路面的质量控制是一项系统工程。首先,应从源头上保证沥青路面所采用集料的质量,控制好各种进场原材料满足技术规范要求;其次,要控制好材料的级配,确保沥青混合料的稳定性、耐久性、抗疲劳、抗渗等性能;另外,选择合理的路面结构是设计的关键;最后,需要强调的是按照城市道路的施工工序控制路基、管道施工及回填、底基层、基层及沥青路面各层的施工工艺和质量,做好路面接缝及与管线相接处的工艺质量,将各种质量隐患消灭在萌芽中。做好上述各点,才能更好地保证城市道路沥青路面的质量,促进社会经济的协调有序发展。

Quality Control of Asphalt Pavement of Urban Road

The quality control of asphalt pavement of urban roads is system engineering. First of all, various raw materials should meet the technical specification requirements in order to ensure the quality of the aggregate in asphalt pavement from the source; secondly, to strictly control the gradation of material in order to ensure the stability, durability, fatigue resistance, permeability and other properties of the asphalt mixture; in addition, the choice of appropriate pavement structure is the key of the design; finally, it should be emphasized that a good process quality of pavement joints and pipeline connecting is necessary to eradicate all kinds of hidden quality problems in the bud, which is in accordance with the technology and quality of city road construction process control, pipeline construction and filling, subbase, base and asphalt pavement construction~ Above all, a better guarantee to the quality of city road asphalt pavement will be obtained, which promotes a Coordinated and orderly development of social and economic.
