Abstract

The invention provides road modified asphalt. The road modified asphalt is prepared from the following raw materials by weight: 100 parts of asphalt, 2-9 parts of spodumene powder, 0.45-3.5 parts of camsellite powder, 0.04-0.3 part of nonylphenol, 0.08-0.6 part of diphenylamine and 0.07-0.5 part of crosslinker, wherein one or more of tetramethyl orthosilicate, aluminum isopropoxide and titanium (IV) acetylacetonate is used as the crosslinker. The road modified asphalt has an excellent flame retarding effect and excellent road service performance. Meanwhile, the release quantities of asphalt smote and waste gas in mixing and paving processes can be effectively reduced. The road modified asphalt has great economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of road asphalt, in particular to a road modified asphalt. Background technique [0002] With the rapid development of today's expressways, some problems of expressways are also exposed. Asphalt is flammable, especially in the case of oil immersion. Fires caused by traffic accidents on expressways will generally ignite the asphalt on the road surface and cause serious damage to the road surface, especially for the asphalt pavement in the tunnel. Once the asphalt on the road surface When ignited, a large amount of heat and dense smoke will be generated during combustion, and the dense smoke is not easy to discharge, which greatly reduces the visibility of the fire scene, delays the timing of fire fighting and saving lives and property, and causes huge losses to the country and people's property. [0003] In addition, the mixing temperature of hot-mix asphalt, which is widely used in road construction and mai...
