| 摘 要： | 利用三维探地雷达技术开展某新建高速公路项目沥青路面的全断面扫描测试，基于共中点法获得沥青路面的介电常数样本，通过与无核密度仪测试样本的相关性，初步确定雷达介电常数的评价范围，从而判别沥青路面大面积施工过程的离析程度，以此指导施工环节的关键技术控制。

Uniformity Evaluation on Mixture Construction for Asphalt Pavement Based on 3D Ground Penetrating Radar |
| |
| Abstract: | 3D ground penetrating radar technology was used to carry out full-section scanning test on asphalt pavement of a newly built highway. Based on common midpoint method, the samples of dielectric constant of the asphalt pavement were obtained with the relevance of the samples tested by non-nuclear density gauge, thus the evaluation range of dielectric constant of the radar was determined initially. The segregation degree during the large area construction of asphalt pavement was thereby distinguished, on which was depended to guide the control of key technology in the construction links. |
