Problems solved by technology

For some special road sections, such as large public parking lots, bus lanes, logistics distribution centers, airport aprons, and port roads, which are prone to diesel and gasoline pollution, road surface damage caused by such pollution is very common. It affects the road driving quality and driving safety in these public areas, but the existing SBS modified asphalt technology cannot solve this problem
And for these areas that are prone to gasoline and diesel pollution, they are usually areas where heavy-duty vehicles gather, so the asphalt pavement in these areas is not only extremely vulnerable to the risk of gasoline and diesel pollution, but also needs to improve the high-temperature anti-rutting ability of the asphalt mixture Therefore, it is necessary to develop a special special modified asphalt that resists oil pollution to improve the ability of the road surface to resist gasoline and diesel pollution, and to enhance the anti-heavy load performance of the road surface

Abstract

The invention discloses an oil-pollution-resistant modified asphalt, whose weight components are: 85-95% of base asphalt, 2-4% of styrene-butadiene-styrene block copolymer, and ethylene-vinyl acetate copolymer 0.5-3%, ethylene-acrylate copolymer 0.5-2%, Fischer-Tropsch wax 0.5-2%, aromatic oil 1-3%, sulfur 0.1-0.2%, silane coupling agent 0.1-0.3%. The invention also discloses a preparation method of the above oil-pollution-resistant modified asphalt. Compared with the prior art, the oil-pollution-resistant modified asphalt of the invention can effectively prevent oil pollution, a special asphalt pavement disease, and simultaneously enhance the heavy-load resistance of the pavement.

Description

technical field [0001] The invention relates to asphalt materials, in particular to an oil-pollution-resistant modified asphalt with excellent oil-pollution-resistance properties and a preparation method thereof. Background technique [0002] At present, the vast majority of asphalt pavements are built by high-temperature mixing and paving of asphalt and stones composed of different grades. However, when diesel oil or gasoline and other similar substances leak onto the asphalt pavement, it will pollute the surface of the road. Asphalt. Since diesel or gasoline is a light component extracted from petroleum, and asphalt used in roads is also a heavy component extracted from petroleum, the two substances have a natural compatibility, and diesel or gasoline will be very Rapidly dilute the asphalt components in the asphalt pavement, causing the loss of cohesion between the asphalt film and the aggregate, and falling off from the aggregate surface. This peeling will develop down...
