Abstract (en)
[origin: US4537796A] In a method of roughening the surface of a concrete slab for roads to provide anti-skid properties, an agent for retarding the setting of the concrete is distributed over the slab which has been recently laid and a water-impermeable sheet of plastics material is spread over the upper surface simultaneously with the spraying operation. After the underlying or subjacent layer of concrete has set, the plastic sheet is lifted away and the still soft upper layer of concrete is removed by brushing and spraying with pressurized water.
