Manufacturing method of concrete pavement slab and concrete pavement slab

摘要

To provide a concrete slab capable of exerting various functions of longitudinal grooves, for example, slip inhibition, drainage, sound insulation.SOLUTION: The concrete pavement slab has a flat plate shape. On the surface of the concrete pavement slab, multiple grooves 6 continuing in a longitudinal direction are formed in parallel. A shoulder portion of the longitudinal groove 6 is chamfered (8). In a flat portion 7 including the chamfered portion (8) and the longitudinal groove 6, aggregates 9 are exposed (rough finishing). The chamfer is formed by placing a resin sheet having shapes corresponding to the longitudinal grooves on the bottom of the form in a manufacturing process of the concrete pavement slab.SELECTED DRAWING: Figure 4
