Abstract

The invention relates to an asphalt pavement seal material as well as a preparation method and application thereof. The seal material comprises high aromatic oil, high gummy oil, a rubber powder modifier, hard asphalt, a plasticizer, a bonding enhancer, a diluent and aggregate. The asphalt pavement maintenance agent can be applied to preventive maintenance of asphalt pavements, is convenient and quick to construct, can form a super-strong protection layer on the asphalt pavements after being used, prevents water and air from entering the asphalt pavements to cause damage to pavement structures, and has a sealing and healing effect on fine cracks of the asphalt pavements. In addition, the asphalt pavement anti-skid agent also has excellent anti-wear and waterproof capabilities, not only can improve the friction force of an asphalt pavement and prevent the anti-skid performance of the pavement from being reduced, but also can protect and repair a binding material lost due to aging on the surface of the asphalt pavement, effectively prevent water from permeating and eroding the internal structure of the pavement, and prolong the service life of the asphalt pavement.

Description

technical field [0001] The invention belongs to the technical field of oil refining and chemical materials, and in particular relates to an asphalt pavement sealing material and its preparation method and application. Background technique [0002] Due to its good performance such as comfortable driving, low noise, and smooth road surface, asphalt roads are more and more used in all levels of roads in our country, especially in our country's expressways, which basically use asphalt roads. However, after the asphalt road is used for a period of time, due to the repeated friction and rolling of the traffic load, natural sunlight, and rain erosion, certain diseases will gradually occur on the road surface. The longer the use time, the deeper the degree of disease. In order to ensure the normal use of asphalt roads, it is usually necessary to implement corresponding preventive maintenance treatments on the asphalt pavement after a certain period of use, so as to prevent road surf...
