排水性沥青混凝土路面具有优良的排水、防滑、降噪等功能,它的高空隙率在发挥其主要功能方面有着至关重要的作用。论文采用8种不同级配研究了排水性全空隙率与有效空隙率的关系,并从集料级配、击实温度、次数及沥青用量等方面研究了不同施工参数对混合料空隙率的影响,对路面的设计及施工具有一定的指导意义。
Drainage asphalt pavement with excellent drainage, anti-skid, noise reduction and other functions, its high porosity in the play its main function has a crucial role. In this paper, the relationship between the total voidage and the effective void fraction was studied in eight different gradations. The effect of different construction parameters on the voidage of the mixture was also studied in terms of the aggregate gradation, the compaction temperature, the number of times and the amount of asphalt. It is of guiding significance to the design and construction of pavement.
