DEVELOPMENT OF EMULSIFIED ASPHALT-AGGREGATE COLD MIX DESIGN PROCEDURE

The development of an emulsified asphalt-aggregate cold mixture (EAM) design procedure is described. The procedure is based on extensive laboratory and field testing, and uses the Marshall stability equipment and a capillary soak test. The procedure consists of conducting aggregate and emulsion quality tests, determining the compatibility of emulsion and aggregate (coating), optimum moisture content at mixing and at compaction, optimum residual asphalt content, and adequacy of structural and durability properties of the mixture. The mix design procedure is intended to be practical and easily implementable by governmental agencies and others. Several mix designs for actual projects were conducted to aid in verification. Results show the procedure to be practical and reasonable. The study has shown that emulsified asphalt-aggregate cold mixtures are complex, and good engineering design is essential to achieve consistently satisfactory results.
