Problems solved by technology

CN10476010607A discloses an intumescent flame retardant for flame-retardant asphalt, consisting of halogen-free and environmentally friendly ammonium polyphosphate, melamine and modified pentaerythritol, but the flame-retardant effect is general
However, due to the relatively closed and narrow space inside the tunnel, there are many limitations when asphalt pavement is used for tunnel pavement, especially for the anti-skid reconstruction of the original cement concrete pavement.

Description

technical field [0001] The invention relates to a pavement pavement material, in particular to a special flame-retardant pavement thin-layer pavement material for tunnels. At the same time, the invention also relates to a method for using the material. Background technique [0002] Based on fire safety considerations, tunnel pavement is often cement concrete pavement. Under the action of huge traffic flow, long-term repeated loads and natural environmental factors, the cement pavement is prone to wear and tear, which leads to a decline in the anti-skid performance of the pavement and affects driving safety. Due to the closed environment and changes in lighting conditions in tunnels, anti-slip road surface is particularly important for safe driving. In order to improve the safety and comfort of pavement traffic and meet the needs of fire protection, it is a simple and easy solution to modify traditional asphalt to prepare flame-retardant asphalt pavement.
