CHEMICAL MODIFICATIONS OF BITUMENS MIXED WITH POLYFUNCTIONAL ORGANIC COMPOUNDS

MODIFICATIONS CHIMIQUES DES BITUMES EN MELANGE AVEC DES COMPOSES ORGANIQUES POLYFONCTIONNELS

AN ATTEMPT WAS MADE TO PREPARE NEW BINDERS BY (1) DIRECT GRAFTING OF MACROMOLECULAR CHAINS AND (2) BRIDGING OF BITUMEN INGREDIENTS BY MEANS OF BIFUNCTIONAL MOLECULES. ONE OF THE DIFFICULTIES WHICH AROSE, WAS TO SHOW THE CHEMICAL COUPLING BECAUSE OF THE COMPLEXITY OF THE REACTIONAL MEDIUM. FURTHERMORE THE NUMBER OF REACTIVE SITES IN BITUMEN IS RELATIVELY LOW. FOR THE COVERING ABSTRACT, SEE IRRD ABSTRACT NO 107043.
