Embodiment approach
[0037] The implementation method of the airport asphalt concrete pavement performance acquisition system provided by the present invention is set forth as follows:
[0038] 1) Install temperature sensor 6, humidity sensor 7, acceleration sensor 8, vibration sensor 9 and limiter 10 all or partly on columnar shell 4 according to the airport pavement monitoring requirements, and test whether they work normally;
[0039] 2) Drill down through the airport pavement to the base layer at the designated positions of the aircraft wheel tracks on both sides of the center line of the airport runway to form a columnar pavement drill with the same maximum diameter as the buried sensor 1 and a depth greater than 5cm of the buried sensor 1 height. hole, and then cut a 2cm wide and 5cm deep slit laterally along the runway from the drill hole on the pavement until it reaches the grass surface area outside the airport pavement, thus connecting the pavement drill hole with the grass surface area; ...

Description
technical field [0001] The invention belongs to the technical field of airport facility detection, in particular to an airport asphalt concrete pavement performance acquisition system and a control evaluation method. Background technique [0002] Airport pavement conditions will directly affect the safety of aircraft takeoff and landing. According to statistical data, the high-incidence periods of civil aviation airliner accidents are mainly concentrated in the stages of takeoff, initial climb and approach and landing. Most of the civil aviation airliner accidents in recent years are related to the deterioration of pavement performance. Because civil aviation accidents directly affect the safe operation of the airport and the safety of passengers, they have always attracted the attention of the airport management department. However, although an industry standard has been established for airport pavement performance testing, so it can be carried out regularly, it is still i...
