COMPOSITION FOR SURFACING LIGHTLY TRAFFICKED THOROUGHFARES, ALLOWING PLANT GROWTH TO BE LIMITED OR EVEN COMPLETELY SUPPRESSED
Disclosed is a draining composition for a light-traffic road pavement, including: (a) a first granular layer having a percentage of communicating voids ranging 25-50%, including a binder and a granular mixture of which at least 80% by weight, relative to the total weight of the granular mixture, has a granular size distribution range 4-20 mm, the layer having a thickness suitable for the pavement's mechanical strength; (b) a second granular layer having main lower and upper surfaces, the main lower surface resting directly on the first granular matrix and the main upper surface in direct contact with the air, the second granular layer being a granular mixture not bound by a binder and of which at least 80% by weight, relative to the total weight of the granular mixture, has a granular size distribution range 2-14 mm, the second granular layer having a thickness appropriate for water accumulation.
