CONCRETE PAVEMENT STRUCTURE COMPRISING A CONCRETE BASE LAYER AND AN ELASTOMER IMPROVED CONCRETE WEARING LAYER

摘要

The invention discloses a concrete pavement structure (1) comprising a base layer (3) directly coated by a wearing layer (2), wherein the base layer (3) is a concrete base layer and the wearing layer (2) is an elastomer modified pervious concrete layer, having a thickness below to 4 cm, a void content in volume ranging from 5% to 20%, more preferentially from 5% to 10%, and the maximal diameter of the aggregates present in said elastomer modified pervious concrete layer is 10 mm. The invention also discloses its manufacturing process, a road comprising it and the use of an elastomer in an elastomer modified pervious concrete layer to improve skid resistance of the pervious concrete layer.
