ABSORPTION OF WATER BY ASPHALT EMULSIONS /IN SPANISH/

THE VISCOSITY OF AN EMULSION DEPENDS MAINLY ON THE ABSORPTION OF WATER BY THE BITUMEN, AN OSMOTIC PROCESS WHICH IS A FUNCTION OF THE SALTS CONTAINED IN THE BITUMEN. THE ARTICLE DESCRIBES TESTS MADE WITH TWO EMULSIONS, IN ONE OF WHICH SODIUM CHLORIDE WAS INTRODUCED IN THE HYDROCARBON PHASE AND IN THE OTHER IN THE AQUEOUS PHASE. FOR THE FIRST TEST INVERTED EMULSION OF BRINE IN OIL WAS PREPARED. THE VISCOSITY OF THIS WAS THREE TIMES THAT OF THE SECOND. BY PROGRESSIVE DILUTION, THE RELATION OF VISCOSITY TO THE BINDER CONTENT WAS VARIED, AND A GRAPH WAS PREPARED FROM WHICH THE PERCENTAGE OF WATER ABSORBED BY THE BITUMEN CAN BE READ. /LCPC/RRL/
