摘要

Improvements in the procedures for obtaining continuous pavements for sports courts, characterized by the fact that the contour of the play area being paved, is provided with a concrete foundation in mass, on which a concrete frame is arranged, as a hoop, which is equipped with transverse holes, arranged in its lower part and with a slight slope to the outside, for drainage of the foundation surface, making the compaction of the firm bounded by the same foundation with slopes from the center towards its sides, whose surface is eventually waterproofed to avoid settlement of the land by the action of the water, by means of an asphalt preparation, according to a first layer in the form of irrigation and a second layer by mechanical spreading, passing then to the construction of the pavement infrastructure by application of a bed of clean aggregates and live edges, according to three layers of successive smaller granulometry and compacted separately, leaving the surface completely level, then the pavement is made on the previous infrastructure, by a layer based on aggregates of sharp edges, kneaded with an asphalt binder, and another layer seen of aggregates of boulders, with the same binder, so that this binder will be duly modified to achieve a continuous horizontal pavement, without expansion joints, permeable and of great resistance, these layers being compacted separately by soft tamping to confer a certain softness to the pavement, allowing elapse before each compaction a prudential time for the evaporation of the solvents and the fluxing oils, and for the breakage of the emulsion, finally taking place a painting with plastic material of the surface of the pavement for its coloring, without occluding the porosity of the same, and the signaling of the game zones by means of otr i painted them to the effect.
