Abstract:
An environment protective pavement, comprising a porous draining and wearing course (1) and at least a porous lower layer (2) comprising bituminous, epoxy or cement binders, used to absorb sound of medium, high and very high frequencies, and a lower supporting layer (5), and a collection system (12,13) of rain water and dangerous liquids or liquid pollutants, the lower supporting layer (5) and the upper layers (1,2) being separated by a cooperating separation layer (3) including spacers (6) transmitting vertical load and transverse forces which are produced by vehicle traffic, said cooperating separation layer (3) being connected on at least one side of a roadway, to a layer acting as a reservoir (9; 9,10) which retains dangerous liquids or liquid pollutants, and which is connected in turn to said collection system (12,13); said spacers (6) being so arranged that they do not hinder rapid transverse flow of water.
