CHARACTERIZATION AND PROPERTIES OF MODIFIED OR STRAIGHT BITUMENS FOR WATERPROOF PAVEMENTS

IDENTIFICATION ET PROPRIETES DE BITUMES MODIFIES OU NON POUR CHAPES D'ETANCHEITE

This study is a contribution to the problem of remedying the intrinsic causes of deterioration observed in certain waterproofing courses in mastic asphalt, particularly those which are intended as substrates for relatively horizontal layers (bridge decks and footways). To this end the characteristics have been examined of about fifty representative products used in the construction of this type of course (modified or unmodified hydrocarbon binders, polymers used in modified binders and bituminous mortars). Of twenty hydrocarbon binders, only three met the only specification currently imposed, namely that the temperature of the ring and ball softening point should be between 70 and 80 degree C. It has been demonstrated that the polymers employed play only a limited or non-existent role in the adhesion between binder and filler in waterproofing courses. This is linked to the dilution of the polymer in the maltene phase of the bitumen.
