PAC-13沥青混合料配合比设计浅析

Analysis on Mix Design of PAC-13 Asphalt Mixture

文中以PAC-13为例,通过检定原材料的性能,以4.75mm筛孔通过率、2.36mm筛孔通过率、1.18~2.26mm集料含量为控制点对矿料级配进行控制。通过分析PAC-13沥青混合料的析漏损失和飞散损失确定最佳沥青用量。通过试铺试验段,研究其路用性能。

This paper takes PAC-13 as an example,through verifying the performance of raw materials,the pass rate of 4.75 mm sieve hole,2.36 mm sieve hole and 1.18 ~ 2.26 mm aggregate content were used as control points to control the aggregate gradation.The optimum asphalt content was determined by analyzing the leakage loss and fly-off loss of PAC-13 asphalt mixture.The road performance is studied through the trial paving test section.
