Abstract

The invention discloses a flame retardant stone mastic asphalt for tunnel pavement. The flame retardant stone mastic asphalt comprises the following components by weight: 3-5 parts of limestone powder, 1-2 parts of an organic flame retardant, 8-12 parts of asphalt and 100 parts of macadam. Further, the organic flame retardant comprises the following components by weight: 10-20 parts of tris(1-chloro-2-propyl) phosphate, 3-7 parts of decabromodiphenyl ether, 5-10 parts of magnesium hydroxide, 5-10 parts of aluminum hydroxide and 20-40 parts of N,N'-ethylene-bis(tetrabromophthalimide). The stone mastic asphalt for tunnel pavement provided by the invention has the advantages of good heat insulation effect, good flame retardance, safety and environment-friendliness.

Description

technical field [0001] The invention relates to a crushed stone mixture, in particular to a flame-retardant asphalt mastic crushed stone mixture for tunnel pavement. Background technique [0002] Tunnels are buildings built underground or underwater and laid with railways for the passage of locomotives and vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills; in order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea; in order to meet the needs of railways passing through large cities, it is called a tunnel. Those that pass underground are called urban tunnels. Among these three types of tunnels, mountain tunnels are the most constructed. [0003] With the rapid development of traffic construction in my country, the ...
