Description
Technical Field
The invention belongs to the field of petroleum industry and basic material chemistry, and particularly relates to an anti-stripping agent, a preparation method and application thereof, which are particularly suitable for an airport asphalt runway.
Background
The airfield runway surface material is divided into two types, namely cement concrete and asphalt concrete, wherein the former is mainly applied to branch airports, and the latter is mainly applied to asphalt concrete finishing of cement runways in trunk airports or branch airports. In China, airports with more than ten million levels of passenger flow mainly adopt asphalt concrete materials as runway pavement materials. The working state of the asphalt concrete material for the airport runway is obviously different from that of the asphalt concrete material for the common highway, and the working state is mainly represented by the following two points: firstly, the high-temperature airflow ejected by the jet aircraft seriously influences the stability of the asphalt concrete material; secondly, after the oil content of the asphalt concrete material is reduced, the surface coarse aggregate is easy to loosen to form foreign invaders (FOD), and once the FOD is sucked into an aircraft engine, serious flight accidents can be caused. Therefore, the improvement of the high-temperature stability and the coarse aggregate shedding resistance of the asphalt concrete material is an important research direction for improving the civil aviation operation safety capability. At present, airport runways in the world are generally paved by polymer modified asphalt with good high-temperature performance so as to deal with the problems of airplane wake baking and road surface deformation and threshing under high shear stress, but the effect is not ideal, and after the airport runway is used for a period of time, the road surface bulges and cracks and the aggregate falls frequently, so that huge flight potential safety hazards and maintenance cost are brought. Therefore, the development of a high-temperature-resistant and anti-stripping asphalt material suitable for being used on an airport runway is urgently needed, a special high-temperature-resistant and anti-stripping evaluation method for the airport asphalt is established, a complete set of systematic and scientific matching technology is formed, and the international and domestic requirements for high-quality asphalt materials in the next thirty years are met.
In order to prevent the asphalt concrete coarse aggregate from falling off to form FOD, the Chinese capital airport adopts a plurality of preventive maintenance measures, such as: atomizing seal, slurry seal and the like, and simultaneously points out that the friction coefficient is reduced after the seal, thereby having influence on the running safety of the runway. As early as 1997, on the basis of analyzing the development history of the asphalt concrete runway in China, people should be pointed out to research and establish the technical standard of the petroleum asphalt and mineral aggregate of the asphalt pavement of the airport and research the modified asphalt and the mixture thereof to reduce the phenomenon of sand and stone shedding, but the problem is not completely solved at present.

The invention relates to an aircraft high-temperature wake flow simulation experiment method, which comprises the following steps: the tail part of the engine is linked with a straight cylinder type cylinder body made of high-temperature resistant materials with a heating function by using an airplane engine (such as a renewed engine). During the experiment, the asphalt to be tested is placed in a metal tray after being melted, and is spread flatly to form a film, and the thickness of the film is 3mm +/-0.3 mm. And (3) placing the tray filled with the asphalt film at the bottom in the cylinder body, and firmly fixing. The bottom of barrel has the heating function, guarantees that the pitch temperature in the tray maintains 60 degrees centigrade +/-20 ℃ (road surface temperature when simulation summer high temperature). Starting the engine, enabling high-temperature tail gas of the engine to enter from one end of the straight cylinder, discharging from the other end of the straight cylinder, enabling the high-temperature tail gas to be blown over the asphalt membrane for 30 minutes and stopping for 10 minutes, and continuously repeating the steps for multiple times. One experimental period was 240 hours from the initial start of blowing. And then taking out the asphalt, analyzing various performances, and comparing the performances with the performances before the simulation experiment. Therefore, the condition of asphalt on an airport runway (particularly a takeoff section) when the asphalt is subjected to high-temperature tail gas blowing of an airplane for a long time is simulated, and the change of the asphalt property, particularly the change of the anti-falling performance is inspected.
In the present invention, the adhesion strength of asphalt is measured by a pull tester. The instrument and test method are as follows:
