【摘要】 提高沥青路面的压实程度是控制其工程质量重要措施之一。利用混合料的介电常数与其组成的固体、液态、气态三相体的介电常数的均方根和体积比的关系,通过常规的室内试验,得到介电常数与沥青路面密度、压实度之间的关系。利用该关系,可用路面雷达快速、实时地检测沥青路面的密实程度,从而实现对沥青路面的施工过程进行控制。更多还原

【Abstract】 Improving the compaction of the asphalt pavement is one of important measures of pavement project quality control.Through normal indoor experiment,according to the relation between the square root of the mixture’s dielectric constant and the square root and volume of the dielectric constant of its solid,liquid and gas,the relevant relation between the mixture’s dielectric constant and the density and compaction of the asphalt pavement can be achieved.By using the relation,the compaction of the asphalt pavement will be detected by GPR quickly and immediately so as to control construction process of pavement.更多还原
