SOIL-EMULSIFIED ASPHALT AND SAND EMULSIFIED ASPHALT PAVEMENT

IN A PAPER ENTITLED, "RECENT DEVELOPMENTS IN THE DESIGN AND CONSTRUCTION OF SOIL-EMULSION ROAD MIXTURES" PRESENTED AT THE 1940 MEETING OF THE HIGHWAY RESEARCH BOARD, FOUR ESSENTIAL STEPS IN THE STABILIZATION OF COHESIVE SOIL WITH EMULSIFIED ASPHALT WERE DISCUSSED. SINCE THEN MUCH ADDITIONAL RESEARCH WORK HAS BEEN CARRIED ON, BOTH IN THE FIELD AND THE LABORATORY. IN THIS WORK THE SUITABILITY OF SANDS FOR BITUMINOUS TREATMENT WAS DETERMINED BY THE FLORIDA BEARING VALUE METHOD AND THE EFFICIENCY OF TREATMENT WAS DETERMINED BY A MODIFICATION OF THE FLORIDA BEARING VALUE METHOD, IN WHICH THE BEARING VALUE OF EMULSIFIED ASPHALT- SAND MIXTURES WAS DETERMINED USING THE SAND FROM THE PROJECT OR BLENDS OF THE SAND AND FILLER WITH VARYING QUANTITIES OF EMULSIFIED ASPHALT TESTED AT VARIOUS TEMPERATURES. THE RESULTS OF THESE TESTS SEEM TO JUSTIFY THE CONCLUSION THAT SANDS ARE SATISFACTORY FOR USE IF THE FLORIDA BEARING VALUE IS GREATER THAN 25 LB, WHEN THE SANDS ARE TESTED PRIOR TO MIXING WITH EMULSIFIED ASPHALT, AND ALSO IF THE MIXTURE SHOWS A BEARING VALUE BY THE MODIFIED FLORIDA TEST METHOD OF MORE THAN 100 LB. AT 140 F ON TESTS AFTER EMULSIFIED ASPHALT IS MIXED WITH THE SAND. THE DATA ARE BELIEVED TO JUSTIFY THE CONCLUSION THAT UNTREATED SANDS WHICH ARE BELOW THE MINIMUM ALLOWABLE STABILITY CAN USUALLY BE MADE SUITABLE FOR USE BY THE ADDITION OF FINE NON-COHESIVE FILLER. /AUTHOR/
