SETTING AND DURABILITY OF ASPHALT EMULSIONS

THE RESEARCH HAS BEEN DIRECTED TOWARDS OBTAINING INFORMATION ON SETTING, TENACITY, AND DURABILITY OF ASPHALT EMULSIONS AND THEIR RESIDUES. NINE EMULSIONS AND FOUR OF THEIR BASE ASPHALTS WERE INCLUDED. THE BREAKDOWN OF EMULSION TYPE IS AS FOLLOWS: (1) 5-CATIONICS USED PRIMARILY FOR CHIP SEALS, (2) 3-RS-2'S USED PRIMARILY FOR TACKING ON FLUSH COATING, AND (3) 1-SS-1H USED FOR SLURRY SEALS. SETTING OR DRYING TIME OF THE EMULSIONS WAS DETERMINED USING A SCRATCH TYPE OF TEST. TENACITY TESTS GAVE A MEASURE OF TENSILE FORCE REQUIRED TO PULL-OUT THE COVER STONES ON A LABORATORY CONSTRUCTED CHIP SEAL. AGING OF THE RESIDUES AND BASE ASPHALTS WERE EFFECTED BY THE SHELL AND ALSO ROLLING THIN FILM OVEN TEST. THE RESULTS SHOWED THAT THE GREATEST DIFFERENCES AMONG THE EMULSIONS WERE IN VISCOSITY OF THE EMULSION AND DURABILITY OF THE RESIDUAL ASPHALTS. /AUTHOR/
