Paving method of durable tunnel pavement
The invention discloses a paving method of a durable tunnel pavement. The paving method comprises the following steps: (1) carrying out sand blasting treatment on a cement concrete plate, spreading rubber asphalt and gravel on the surface of the cement concrete plate, and grinding to form a rubber asphalt and gravel seal coating; (2) grinding to form an asphalt mixture substrate on the rubber asphalt and gravel seal coating, pouring cement-based mortar, and naturally curing to form a poured semi-flexible paving lower layer; (3) spreading modified emulsified asphalt so as to form a modified emulsified asphalt layer; and (4) paving a fine-grain type asphalt mixture or a medium-grain type asphalt mixture to form a high-modulus warm mixing inflaming-retarding asphalt mixture paving upper layer. According to the invention, the paving method is strong in universality and simple in construction process, adopts a relatively conventional material, is strong in operability, and has good construction peaceability; with the whole paving structure, design service life can be obviously prolonged and can achieve 20-30 years, and good fireproofing, skid resistance, safety, as well as energy conservation and environment protection effects are achieved.
