Abstract (en)

[origin: FR2779424A1] The invention concerns a composition and a method for producing a road surface course for roadways with little or moderate traffic corresponding to not more than about 5000 vehicles per day. The composition is based on black japanned aggregates, the aggregates being 2/4 to 2/6 chippings and the lacquering being obtained by a bitumen emulsion. When the surface course is being produced, sand and a bitumen emulsion with controlled fracture and viscosity are spread over the black japanned aggregate composition surface, the whole being then compacted. The invention also concerns a corresponding surface course.
