填充料细度对水工沥青混凝土性能的影响

近年来沥青混凝土作为防渗材料，在我国水工建筑中得到了广泛应用。与道路工程的沥青混凝土不同的是，水工沥青混凝土具有良好的粘弹性及抗渗性。目前，国家规范对填充料的细度尚无明确规定，通过调整沥青混凝土的填充料细工，对沥青混凝土的各项性能进行了系统的试验和分析，研究表明：适宜的填充料细度及掺量，能有效地改善沥青混凝土性能，提高其抗渗性。

Effect of Fineness of Filling on the Properties of Asphalt Concrete

As an impermeable material, asphalt concrete has been widely used in hydraulic projects in our country for these years. Being quite different from the asphalt concrete used in highways, water proofing asphalt concrete must have good viscosity, elasticity and anti permeablity. According to the research we have done, it was proved that the properties of asphalt concrete could be improved by selecting suitable fineness and amount of filling. There haven't been clear and definite national specifications for the fineness of filling until now. Systematic tests have been done by adjusting the fineness of filling to analyze all kinds of properties of asphalt concrete, and it was concluded that better fineness of filling could effectively improve the comprehensive properties of asphalt concrete.
