Development and Application to the Test Pavements in the Real Way of Eco-Friendly Hybrid Type Permeable Concrete Pavement

A new type of pavement structure was proposed and applied to the construction of two different trunk roads. The hybrid structure is composed of two basic layers of the porous concrete surface course which has sufficient functions of smoothness, skid resistance, permeability and low noise and of the less permeable concrete base course which has good supporting capacity. This paper describes the pavement structure, mix proportion design, the construction method and evaluation of pavement performance based on the data collected of the paving section in service. Un nouveau type de revetement a ete propose et mis en place pour la construction de deux differentes routes nationales.Le revetement hybride est compose de deux couches de beton poreux qui offre des qualites de surface unie,de resistance au derapage,de permeabilite et de niveau sonore et une couche de beton moins permeable qui offre de bonnes capacites de support. Ce document decrit la structure de revetement, la conception a proportions melangees, la methode de construntion et levaluation de la performance du revetement basee sur les donees collectees sur les sections revetues en service.
