重庆江北国际机场沥青道面监测与分析

In order to study and monitor the diseases of airport asphalt pavement, and to solve the passive situation of lacking of airport asphalt pavement working data in our country, the asphalt pavement monitoring system is established at Chongqing Jiangbei international airport and the response is analyzed. By using the layout of fiber Bragg grating sensors, information fusion and WLAN technology, the monitoring system for airport asphalt pavement structure acquisition was established, based on which, aircraft load position distribution characteristics, taxing speed, pavement temperature environment and pavement response characteristics under the representative load and temperature condition were analyzed. Results show that airport asphalt pavement response can be continuously obtained by the pavement monitoring system. And, the data and video are not lost. Aircraft load migration obeys normal distribution. Aircraft taxing speed at taxing way is 20~30km/h. Airport asphalt pavement strain response is much higher than that of highway asphalt pavement.
