Abstract
The invention discloses an anti-stripping aging-resistant warm-mix agent, a preparation method and application thereof. The anti-stripping aging-resistant warm-mixing agent comprises the following raw materials: styrene-butadiene-styrene copolymer, styrene butadiene rubber, styrenated phenol, resin, alkyl ammonium chloride, coupling agent, antioxidant, surfactant and aromatic oil. The anti-stripping aging-resistant warm mix agent is particularly suitable for airport runway asphalt, can obviously improve the anti-stripping and aging-resistant properties of asphalt, can reduce the occurrence of asphalt smoke, and is beneficial to environmental protection.
Description
Technical Field
The invention belongs to the petroleum industry and the basic material chemistry field, in particular to an anti-stripping aging-resistant warm mix agent, a preparation method and application thereof, which are particularly suitable for airfield runway asphalt.
Background
Asphalt mixture can generate a large amount of asphalt smoke in the production and paving process, and the environment is influenced. Along with the improvement of environmental protection requirements, especially the formulation of a double-carbon target, the asphalt pavement needs to reduce the occurrence amount of asphalt smoke during construction. In the using process of asphalt, the more the volatilization amount of light components is, the smoke amount of asphalt is increased along with the increase of the using temperature. Practice proves that the adoption of the warm mixing technology is an effective method for reducing the occurrence amount of asphalt smoke by reducing the mixing and construction temperature of asphalt mixture.
The problem of stone falling off on an airport runway is different from the situation on a highway, the highway mainly aims at water damage, and the purging effect of a jet aircraft with high Wen Weiliu is mainly considered on the airport runway, so that the temperature of the runway surface is rapidly increased due to high temperature (850-900 ℃), large airflow and high airflow speed (180 m/s), the temperature of the aircraft is reduced after the aircraft passes, and the aircraft is always in frequent fluctuation of the temperature, so that asphalt aging, fatigue, damage and threshing on the runway surface are easily caused. There is no anti-spalling agent developed specifically for the problem of asphalt concrete stone fall-off of airport runways due to the influence of jet aircraft altitude Wen Weiliu.
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 the temperature, the asphalt pavement is ablated and softened by high-temperature tail gas flow sprayed by the airplane, and the ablation area of each part 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 anti-stripping and anti-aging warm mix asphalt material suitable for use on airport runways.
