MACHINE FOR THE TRANSVERSE ROUGHENING TREATMENT AND PULVERIZING A CURING COMPOUND ON FRESH CONCRETE /IN FRENCH/

DETAILS ARE GIVEN OF A PROTOTYPE MACHINE, DEVELOPED BY THE CENTRE DE RECHERCHES ROUTIERES, FOR TRANSVERSE ROUGHENING OF CONCRETE ROADS AND FOR PULVERIZING CURING COMPOUND ON FRESH CONCRETE. THE MACHINE IS FULLY AUTOMATIC, AND THE ROUGHENING DEVICE CAN HAVE METAL BLADES OR TUFFS OF METAL, COCONUT FIBRE OR P.V.C. SPECIAL DEVICES CONTROL THE QUANTITY OF CURING COMPOUND APPLIED, PREVENT THE CLOGGING OF THE JETS, ENSURE A CONSTANT HOMOGENEIZATION OF THE CURING COMPOUND AND PREVENT IT FROM BEING BLOWN AWAY BY THE WIND. THIS ROUGHENING FACILITATES THE RAPID DRAINAGE OF SURFACE WATER, AND GIVES A HIGH DEGREE OF ROUGHNESS IN WET WEATHER ENABLING VEHICLES TO TRAVEL AT HIGH SPEED. IT DOES NOT IMPAIR THE RIDING QUALITY OF THE PAVEMENT AND HAS THE ADVANTAGE OF REDUCING GLARE. /CRIC/FESR/LCPC/A/RRL/
