FIFTH SYMPOSIUM: COLD-COATED MATERIALS. EXPERIMENTS ON COLD-COATED MATERIALS CONTAINING ANIOMIC EMULSIONS, IN ARGENTINA
1974
A DESCRIPTION IS GIVEN OF LABORATORY AND IN-SITU EXPERIMENTS ON THE USE OF COLD-COATED MATERIALS CONTAINING ANIONIC EMULSIONS, ON THE PROPERTIES OF AGGREGATES USED, AND METHODS OF CONSTRUCTING WEARING COURSES. IT IS SOMETIMES IMPOSSIBLE TO USE HOT-COATED MATERIALS FOR WEARING COURSES BECAUSE OF ECONOMIC, TECHNICAL AND CLIMATIC CONDITIONS AND BECAUSE THE AGGREGATES MUST BE USED IN THEIR NORMAL MOISTURE STATE. DETAILS ARE GIVEN OF SEVERAL METHODS OF COATING AGGREGATES (COLD AND WET) WITH BITUMINOUS BINDERS. ASPHALTIC EMULSIONS APPEAR TO BE SATISFACTORY FOR THIS PURPOSE; IF JUDICIOUSLY SELECTED, THEY FACILITATE THE PRODUCTION OF HIGH-QUALITY BITUMINOUS MIXTURES FOR ROADBASES, BASES AND WEARING COURSES. FOR THE COVERING ABSTRACT OF THE SYMPOSIUM, SEE IRRD ABSTRACT NO. 104352.
