摘　　要： 为了能通过识别沥青路面在雨天饱水后的表面温度差异性对其透水性进行评价,首先对路表温度场与透水性的相关性进行分析,然后基于高速红外调制探头等硬件以及红外路表测温、信号转换和色谱绘制等软件系统,开发了一种该领域内首台连续测速达到100km/h的沥青路面透水性红外差热检测仪。研究结果表明,通过用红外测温技术检测的路面温度差异度对沥青路面透水性进行评价是可行的。与传统的定点式渗水仪相比,红外透水性检测仪的检测效率提高了50倍,相关系数达到0.8985。该仪器与智能型雾封层洒布车共享路面透水性数据信息,形成了成套的沥青路面透水性处治技术。此外,配套的高速公路沥青路面透水性评价标准(2008/04007)足以满足中国不同区域和各种等级公路的检测要求。 An infrared differential thermal detector for asphalt pavement permeability is developed. The detector is based on a high speed infrared detector system and a software system including infrared surface temperature measurement, signal conversion, chromatography, etc. It is the first infrared differential thermal detector which can continuously operate at a speed of 100 km/h in the field of asphalt pavement permeability measurement. The research result shows that it is feasible to evaluate the permeability of asphalt pavement by measuring the surface temperature difference of asphalt pavementwith the infrared temperature measurement technology. Compared with the traditional fixed-point per- meability detector, its detection effectiveness is improved by a factor of 50 and its correlation coefficient is up to 0.8985. Because the system can share the pavement permeability information with an intelligent fog seal asphalt distributor, it can form a complete asphalt pavement permeability treatment technology which meets the requirements of different highways in China.
