Problems solved by technology

Due to the dense structure of ordinary cement concrete pavement, the sound absorption efficiency is relatively low, and the road has strong reflection of sound, the noise pollution caused by vehicles running on cement concrete pavement is more serious than that of asphalt pavement.
For the anti-slip and noise reduction of asphalt pavement, scholars at home and abroad mainly use asphalt mixture with large porosity and open grading, but this material has poor fire resistance, anti-rutting, and water damage resistance. Anti-slip function suitable for tunnel engineering asphalt pavement materials

Abstract

A fire-proof, noise-reducing and antiskid material for the pavement in tunnel is prepared through preparing flame-retarding smoke-inhibiting agent from decabromodiphenyl ether, Sb2O3, aluminium hydroxide and smoke inhibitor, preparing modified high-viscosity flame-retarding asphalt from styrene-butanediene-styrene block copolymer, activated rubber powder, stabilizer, antioxidizing agent, said flame-retarding smoke-inhibiting agent and asphalt matrix, choosing mineral material consisting of aggregate and filler, and mixing it with said modified asphalt and fibers.

Description

technical field [0001] The invention belongs to the field of material science and engineering, and in particular relates to a preparation method of pavement materials. technical background [0002] With the rapid development of the national economy and the continuous expansion of the scale of urban construction, the urban traffic conditions in my country are becoming more and more congested. The construction of underground and mountainous tunnels and the development of tunnel traffic systems have become the focus of the development of urban traffic and mountainous traffic in my country at this stage. Tunnel construction not only requires high traffic efficiency, safety and driving comfort, but also requires outstanding environmental protection features. Tunnel noise control is a systematic project. In addition to installing high-performance sound-absorbing decorative materials around the tunnel, the selection of tunnel pavement materials and structural design are crucial to ...
