Problems solved by technology

[0004] However, no matter any of the above-mentioned colored asphalt materials, it mainly consists of hydrocarbons. When a fire occurs on the road surface, these substances will play a role in supporting combustion and aggravate the fire. Especially in closed environments such as tunnels, once a fire occurs, the asphalt The road will catch fire or smoke at the same time, which will increase the difficulty of tunnel rescue and cause great property and personal casualties

Abstract

The invention relates to the technical field of road engineering materials, in particular to a flame-retardant colored asphalt material and further discloses a preparation method of the flame-retardant colored asphalt material. The flame-retardant colored asphalt material disclosed by the invention is prepared from the microalgae oil, SBS, hydrogenated petroleum resin, magnesium-aluminum-zinc carbonate type layered double hydroxide loaded with nano titanium dioxide, bamboo-wood fibers, KYS powder and inorganic pigment as preparation raw materials. The flame-retardant colored asphalt material not only has excellent high-temperature performance and flame-retardant performance and better environmental protection performance, but also is simple in preparation process and relatively low in cost. The flame-retardant colored asphalt material can be suitable for places such as walkways, garden landscape roads, road intersection warning areas and expressway deceleration strips, has a general road passing function, has visual aesthetic feeling, and has a warning effect and the like.

Description

technical field [0001] The invention relates to the technical field of road engineering materials, in particular to a flame-retardant colored asphalt material, and further discloses a preparation method thereof. Background technique [0002] With the rapid development of my country's transportation infrastructure, people have put forward higher requirements for the coordination between asphalt pavement and the environment under the premise that road traffic meets the basic needs of daily travel. The traditional black asphalt pavement can no longer satisfy people in terms of color. demand, the new colored asphalt pavement has gradually been recognized by everyone because of its convenient traffic management guidance, prevention of traffic accidents, beautification of the city image, reflection of the city's characteristics and landscape benefits, and has been widely used in highways, urban roads, tourism, etc. Scenic and dedicated electronic toll lanes for emergency services an...
