| 摘 要： | 提出了利用红外热差原理的沥青路面渗水状况快速评价技术,基于开发的红外快速渗水检测车,重点研究了现场路面温差与渗水系数关系判定准则。依托实体工程,对红外快速渗水检测车的测试结果进行人工复核,并与路面钻取芯样的浸水飞散损失比对。结果表明:红外渗水检测车测试的结果不仅能与现场路况一一对应,且与室内试验结果相关性好;作为一种快速评价路面渗水状况的技术,效率、精度均较高。

| Abstract: | In the paper,thermal infrared technology is proposed to quickly evaluate asphalt pavement water seepage condition,and based on the rapid development of infrared water seepage check-out car,the relationship between the field road surface temperature and water seepage coefficient criterion is studied,relying on an actual project,the test results of infrared rapid seepage check-out car are checked by people,and compared with flooding flying loss ratio in the pavement by drilling.The results show that the infrared water seepage check-out car test results are not only corresponding with site traffic,but have a good correlation with indoor test results.As a technique for rapid evaluation of pavement seepage,the method has high efficiency and precision. |
