Abstract

Abstract: To assess the impact of factors affecting the dielectric constant of asphalt concrete, we studied the inhomogeneous composition of asphalt concrete material dielectric properties, considering the impact on the dielectric constant of bitumen content, unit weight and moisture content. The results show that at the same porosity range, asphalt concrete specimens dielectric constant decreases with increase of asphalt content；asphalt concrete specimen’s dielectric constant can be calculated by the mixed theoretical model；asphalt concrete density can be predicted by dielectric constant,porosity and asphalt content.

Key words: road engineering, asphalt mixture, dielectric constant, influence factors

摘要： 为评估沥青混凝土混合料介电常数的影响因素，研究了非均质沥青混凝土组成材料的介电性质，考虑沥青含量、密度、含水率对介电常数的影响。结果表明：在相同孔隙率范围时，沥青混凝土试件介电常数随沥青含量增加而降低，可由介电混合理论模型计算；沥青混凝土密度可由沥青混凝土试件介电常数、孔隙率及沥青含量加以预测。
