ASPHALTIC CONCRETE CONTAINING EMULSIFIED ASPHALT. DESIGN AND CONSTRUCTION TECHNIQUES

THE PROPERTIES OF ASPHALTIC MIXTURES, MANUFACTURED WITH SLOW SETTING EMULSIFIED ASPHALT, ARE DIRECTLY INFLUENCED BY THE AGGREGATE GRADING, MOISTURE CONTENT OF THE MIXTURE, PERCENTAGE OF EMULSION, AND COMPACTION CONDITIONS. THESE VARIABLES ARE STUDIED, AND SPECIFICATIONS ARE PROPOSED FOR THE CORRECT PROPORTIONING, COMPACTION AND QUALITY CONTROL OF THE MIXTURES. A TABLE PRESENTS COEFFICIENTS, BASED ON AGGREGATE GRADING, FOR DETERMINING THE OPTIMUM WATER CONTENT OF MIXTURES MANUFACTURED FROM LOCAL MATERIALS (GRANITE, QUARTZITE AND SILICEOUS AGGREGATES). THE PERCENTAGE OF RESIDUAL MOISTURE NECESSARY FOR GOOD COMPACTION IS ESTABLISHED. ATTENTION IS DRAWN TO THE ECONOMIC AND CONSTRUCTIONAL ADVANTAGES ON THE ABOVE MIXTURES, PARTICULARLY AS REGARDS (A) THEIR PLASTICITY DURING TRANSPORT AND HANDLING, (B) THEIR EASY USE, (C) THEIR WORKABILITY, AND (D) THEIR EASY MIXING WITH COLD AND WET AGGREGATES. DISADVANTAGES OF THESE MIXTURES ARE ALSO DISCUSSED. /TRRL/
