The airports with passenger flow above China millions mainly adopt asphalt concrete materials as runway surface materials. The working state of the asphalt concrete material for the airfield runway is obviously different from that of the asphalt concrete material for the common highway, and the asphalt concrete material mainly comprises the following two points: firstly, high-temperature air flow sprayed by a jet aircraft seriously affects the stability of asphalt concrete materials; secondly, asphalt concrete materials are easy to loosen surface coarse aggregates to form foreign invaders (FODs) after oil content is reduced, and the FODs can cause serious flight accidents once being sucked into aircraft engines. Therefore, the high-temperature stability and the coarse aggregate shedding resistance of the asphalt concrete material are improved, and the method is an important research direction for improving the civil aviation operation safety capability. At present, polymer modified asphalt with better high-temperature performance is widely adopted for paving airport runways worldwide so as to solve the problems of pavement deformation and threshing under the conditions of aircraft wake baking and high shear stress, but the effect is not ideal, and after a period of use, pavement bulges crack and aggregate fall frequently, so that huge flight potential safety hazards and maintenance cost rise. Therefore, development of a high-temperature-resistant and anti-stripping asphalt material suitable for airport runways is urgently needed, a special high-temperature-resistant and anti-stripping evaluation method for airport asphalt is established, a complete set of system scientific matching technology is formed, and the requirements of the next thirty years on high-quality asphalt materials at home and abroad are met.
In order to prevent the asphalt concrete coarse aggregate from falling off to form FOD, the first airport of China adopts a plurality of preventive maintenance measures such as: atomization seal, slurry seal, etc., and simultaneously indicates that the friction coefficient can be reduced after seal, which has an effect on runway operation safety. As early as 1997, on the basis of analyzing the development history of China asphalt concrete runway, the technical standard of making airport asphalt pavement petroleum asphalt and mineral aggregate is pointed out, modified asphalt and mixtures thereof are researched, and the phenomenon of sand and stone falling is reduced, but the problem is not completely solved up to the present.

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.

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