CHIPPINGS GROUT WITH RESIN BINDER: A THIN, NON-SKID SURFACING FOR CONCRETE
LE COULIS GRAVILLONNE A LIANT RESINEUX: UN REVETEMENT MINCE ANTIDERAPANT POUR BETON DE CIMENT
This grout is used for the surfacing of concrete structures or pavements where permanent high roughness is required. Details are given of the structure of the surfacing, its ingredients and laying methods. The self-levelling grout or mortar with 30% resin is spread at the rate of 6,5 kg/sq metre on previously scraped concrete; the grout is then covered with 4/6 mm chippings. These aggregates must have a high resistance to polishing and wear; calcined bauxite, natural emery and zirkorit are used. An experiment was carried out in 1975, in which 6 mix-design formulae containing resin binders were used. After 3 years the general behaviour of the surfacings is excellent, the coefficients of lateral friction are high and only a little lower when speed increases. The rolling noise level is markedly less high than on other road surfacings of satisfactory roughness. Calcined bauxite gives lateral friction coefficients higher than the other two aggregates; for the six varieties of resin binders which conformed to specifications, no difference in results was observed from the point of view of adhesion of the grout to the base and fixing of the chippings.
