Background
When the temperature in summer is 40 ℃, the TY-104 aircraft is used for a blowing test, and the highest temperature of the asphalt pavement can reach 141 ℃. At this time, the asphalt pavement is ablated and softened by high-temperature tail gas flow sprayed by the airplane at a plurality of positions, and each ablation area is 3-5 cm 2 . The asphalt runway is continuously subjected to the blowing of the high Wen Wei airflow of the airplane, so that asphalt aging is easy to cause, coarse stone on the surface is further caused to fall off, and once the fallen stone is sucked into an engine of the airplane, serious flight accidents are caused. Therefore, the high-temperature stability and the coarse stone shedding resistance of the asphalt concrete material are improved, and the asphalt concrete material is an important research direction for improving the civil aviation operation safety. At present, polymer modified asphalt with better performance is widely adopted for paving airport asphalt runways worldwide, so that the problems of airplane wake baking, road surface deformation and threshing under high shear stress are solved. However, the practical effect is not ideal, and after a period of use, the pavement bulges, cracks and stone fall frequently occur, so that the potential safety hazard and the maintenance cost are increased. Therefore, there is an urgent need to develop an aging-resistant, anti-falling and aging-resistant asphalt material suitable for use on airport runways.
At present, the researches on the failure mechanism of the airport asphalt concrete pavement and the modified asphalt concrete materials comprise the following steps: the damage cause of the acetic acid-based snow-melting agent to the road surface of asphalt concrete is studied by university of Changan, peng Zixin and the like, and asphalt emulsification caused by acetate is analyzed. The phenomenon of FOD caused by the falling of coarse stones on the pavement of asphalt concrete and engineering treatment measures are analyzed by the university of Tongji Tan Yue and the like. The temperature change rule and the high-temperature stress fatigue characteristic of the tensile strength of the asphalt concrete pavement material are analyzed through a large amount of statistical data in the air force university Weng Xing, and the change of the strength under high-temperature stress is considered to seriously influence the runway safety. The university of the same university Liu Wen, etc., indicates the effect of temperature on runway performance based on comparing various asphalt concrete runway design influencing factors, but no in-depth analysis has been made. At present, no anti-stripping and anti-aging agent is developed specially for the problem of asphalt concrete stone falling off of an airport runway caused by the influence of jet aircraft height Wen Weiliu.

In the invention, the simulation experiment method of the aircraft height Wen Weiliu comprises the following steps: with aircraft engines (such as newer engines), the tail links a straight barrel of high temperature resistant material with heating. During the experiment, put into metal tray after melting the pitch that waits to test, the flat spreading is the film form, and film thickness is 3mm + -0.3 mm. The tray with the asphalt film is arranged at the bottom in the cylinder body and is firmly fixed. The bottom of the cylinder body has a heating function, so that the temperature of asphalt in the tray is maintained at 60+/-20 ℃ (the temperature of Wen Shilu table in summer simulation). The engine is started, so that high-temperature tail gas of the engine enters from one end of the straight cylinder, the other end of the straight cylinder is discharged, the high-temperature tail gas is blown over the asphalt membrane, the blowing is continued for 30 minutes, and the blowing is stopped for 10 minutes, so that the process is continuously repeated for a plurality of times. One experimental period was 240 hours from the initial start of blowing. And then taking out the asphalt, analyzing each performance, and comparing the performance with the performance before the simulation experiment. The method simulates the condition of asphalt on an airport runway (especially in a take-off section) when the asphalt is purged by high-temperature tail gas of an airplane for a long time, and examines the change of asphalt properties, especially the change of anti-falling performance.
In the invention, the asphalt adhesion strength is obtained by testing with a drawing tester. The instrument and the test method are as follows:

As can be seen from table 2, the addition of the anti-stripping and anti-aging agent of the invention to asphalt can significantly improve the adhesion strength and anti-stripping performance of asphalt; after a period of aircraft height Wen Weiliu simulation experiment, the adhesion strength of the asphalt added with the anti-stripping and anti-aging agent is not reduced, but is increased, so that the anti-stripping and anti-aging agent not only can improve the anti-stripping performance of the asphalt, but also has stronger anti-aging capability and strong adaptability to the aircraft height Wen Weiliu environment. The asphalt without the anti-stripping and anti-aging agent has obviously reduced adhesion strength after simulation experiments, which indicates that the anti-aging capability is weaker; after a certain commercial anti-stripping agent is added, compared with the anti-stripping anti-aging agent provided by the invention, the anti-stripping anti-aging agent has smaller improvement range of adhesion strength, and after a simulation experiment, the anti-stripping anti-aging agent has smaller improvement range of adhesion strength.
