DOPES IN BITUMENS. DETECTION AND INTERACTIONS

LES DOPES DANS LES BITUMES - DETECTION ET INTERACTIONS

THE AUTHORS SHOW THE DIFFICULTY OF DIFFERENTIATING BETWEEN THE BASIC INGREDIENTS OF BITUMEN AND THE AMINES CONTRIBUTED BY THE DOPE. THEY ALSO SHOW THAT THE BITUMEN'S CARBOXYLIC ACIDS CAN REACT WITH THE WETTING AGENTS IN A WAY WHICH DOES NOT ALWAYS RESULT IN AN IMPROVEMENT IN THE SURFACE PROPERTIES OF DOPED BINDERS. A SIMPLE TEST IS PROPOSED FOR DETECTING DOPES BY EVALUATING THEIR EFFICIENCY IN THE WETTING OF AGGREGATES WITH DILUTED DOPED BINDERS. FOR THE COVERING ABSTRACT OF THE WHOLE NUMBER, SEE IRRD ABSTRACT NO 107043.
