Abstract

The invention discloses an asphalt anti-aging agent applied to a tropical coastal area. The anti-aging agent has a good flame-retardant smoke-suppressing effect through combined interaction of micro-nano-sized brucite powder with raw vermiculite powder and flame-retardant polyamide 66 composite fiber in a combustion process, so that the flammability of asphalt is reduced effectively, and the safety of use and construction of asphalt pavements is improved; meanwhile, the impact of high temperature on asphalt can be reduced effectively through addition of the brucite powder and the flame-retardant polyamide 66 composite fiber, and corrosion of chloride ions and other inorganic salts in sea water to asphalt pavement materials can be resisted through addition of an iron diethylene triamine pentaacetate-sodium complex; and the anti-aging agent is obtained mainly through grinding of natural minerals, has no phosphorus, no halogen, no adverse effects on the environment, and has significant environment-friendly benefits.

Description

technical field [0001] The invention relates to the technical field of modified asphalt, in particular to an asphalt antiaging agent used in tropical coastal areas and a preparation method thereof. Background technique [0002] In recent years, my country's high-grade highways are gradually extending from plains and slightly hilly areas to mountainous and heavy hilly areas, so the construction of tunnels has achieved rapid development. Asphalt pavement material is widely used in tunnel pavement because of its advantages of comfortable driving, low noise and high traffic safety. However, while the tunnel traffic is constantly improving, the risk of tunnel fire accidents is also increasing. When accidents such as collision of faulty vehicles and spontaneous combustion of vehicle-loaded goods occur in the tunnel, it is very easy to cause tunnel fire accidents. Once a fire breaks out in the tunnel, the asphalt will participate in the combustion and produce a large amount of sm...
