The invention discloses a material on a tunnel drainage layer, which is characterized by comprising the raw materials with the following parts by weight: 100 parts of rubber particles, 20-50 parts of mineral wool fibres and 50-80 parts of VAE emulsion. The material adopts water conductivity of inorganic fibers, elasticity of waste vulcanized rubbers and cohesiveness of the VAE emulsion, and on the basis of better drainage property, has the leveling function to fill and level up upper concave pits and has the elastic function to be adaptive to deformation of the upper structure, changes the construction technology, can carry out direct injection, improves the construction efficiency and reduces the labor intensity of workers.
