SPECIAL SURFACE CONDITIONS

ETATS DE SURFACE PARTICULIERS

THE AIM OF THE RESEARCH IS TO OBSERVE OVER A CERTAIN PERIOD OF TIME THE ADHESION OF A NUMBER OF SPECIAL SURFACINGS WITH A VIEW TO CONTROLLING THEIR NON-SKID PROPERTIES AND THEIR APTITUDE TO BE USED IN WEARING COURSES. THE MAIN POINTS OF THE STUDY WILL BE: BITUMINOUS MIXTURES FOR MAINTENANCE; DRAINAGE BITUMINOUS MIXTURES. OTHER TECHNIQUES COULD ALSO BE TESTED (MIXED BITUMINOUS MIXTURES, VARIOUS SPECIAL MIXTURES, ASPHALTIC CONCRETE SPREAD WITH PRECOATED CHIPPINGS).
