摘要
为准确评价沥青路面结构内部破损状况,选用三维探地雷达进行路面检测,基于山东省内三条高速公路的隐性病害检测数据,针对影响路面结构性能的裂缝、结构松散、层间黏结不良等隐性病害进行量化分析,提出沥青路面结构性能评价指标,结合钻芯取样法验证其有效性。
In order to accurately evaluate the internal damage of asphalt pavement structure,the threedimensional ground penetrating Radar was used to detect the pavement.Based on the hidden disease detection data of three expressways in Shandong Province,the quantitative analysis of hidden diseases such as cracks,loose structure and poor interlayer bonding that affect the performance of pavement structure is carried out.And the performance evaluation index of asphalt pavement structure is proposed,combined with the core drilling sampling method to verify its effectiveness.
