Abstract:
A SMALL AMOUNT OF ASPHALT IN THE FORM OF A PROPERLY MANUFACTURED EMULSION, WHEN MIXED WITH CLAY BEARING SOILS OR AGGREGATES, AND ALLOWED TO DRY, ENTIRELY CHANGES THE CHARACTERISTICS OF THE MATERIALS. THE AMOUNT OF ASPHALT USED IS CRITICAL SINCE THE SOILS MUST RETAIN AS MUCH WATER- PROOFNESS AND STABILITY AS POSSIBLE. THE AMOUNT OF EMULSION REQUIRED TO PROPERLY TREAT A MATERIAL USUALLY VARIES IN ABOUT DIRECT PROPORTION TO THE AMOUNT OF FINES PRESENT IN THE SOIL. A STABILIZED FOUNDATION COURSE NEEDS A THIN ASPHALTIC WEARING SURFACE TO PROTECT IT FROM THE TRAFFIC. IN USING EMULSIFIED ASPHALT STABILIZATION IT IS IMPORTANT TO CONSIDER PROPER MIXING, ADEQUATE COMPACTION, THOROUGH DRYING, AND PROPER SURFACE PROTECTION.
