摘要
通过对沥青路面上钻取的非干燥试件进行风干和烘干试验,计算不同试验条件下心样的毛体积相对密度和压实度。研究结果表明,风干12 h以后继续延长风干时间,对路面压实度的计算结果影响甚微,而在不需进行其他试验时,采用（60±5）℃烘箱烘干0.5-1.5 h后称其空中质量进行路面压实度评价是合适的,且有利于指导沥青路面的连续施工。
By the density test of blow-drying and stoving of non-aridity core sample from asphalt pavement, the bulk volume relative density and compactness can be calculated under different test conditions. The study shows it has little influence on the calculation results of asphalt pavement compactness when the blow-drying time is over twelve hours. It is appropriate to evaluate asphalt pavement compactness by stoving the non-aridity core sample from half an hour to one half hours in oven at （60±5）℃ if the core sample needn＇t to be used in other tests again. In addition, it is favorable to continuous construction of asphalt pavement.
