Abstract

The invention discloses a cement pavement fine friction course and a construction method. The fine friction course is paved by fine aggregates, an epoxy binder, cement, additives and a stabilizer. Theconstruction method comprises the following steps: closing a construction section, polishing old cement pavement, repairing local diseases and cleaning the pavement; then, blending the epoxy binder,cement and additives on the spot by adopting a special synchronous chip sealer to obtain epoxy cement, synchronously spraying the epoxy cement and fine aggregates onto the cement pavement to form an epoxy friction thin course, and rolling for 1-2 times by adopting a tire roller; spraying the stabilizer to the epoxy friction thin course by adopting an asphalt distributor after the epoxy friction course is cured, and handing over after the course is maintained and molded, and is qualified in inspection. The cement pavement fine friction course has the advantages of strong affinity with cement pavement, good binding force, water resistance, skid resistance, abrasion tolerance and the like, can be used for quickly repairing the surface structure of an old cement concrete pavement so as to improve the pavement skidding resistance and the pavement appearance.

Description

technical field [0001] The invention relates to the related field of maintenance and repair of cement concrete pavement, in particular to a fine anti-skid wear layer of cement pavement and a construction method. Background technique [0002] Cement concrete pavement is widely used in bridge and tunnel pavement because of its advantages of high strength, good stability and excellent construction environment. However, the macroscopic structure and microscopic texture of cement concrete pavement are gradually worn away shortly after it is opened to traffic, and the problem of anti-skid pavement is becoming more and more prominent. Especially, traffic accidents on bridges and tunnels occur frequently, and the driving safety of cement concrete pavement on bridges and tunnels has attracted much attention. [0003] Aiming at the anti-skid problem of cement concrete pavement of bridges and tunnels, the more commonly used maintenance method is the horizontal groove method, but the co...
