OPTIMUM PROPORTIONS FOR SAND SHELL MIXTURES

THE LABORATORY STUDIES INDICATED THAT OPTIMUM MIXTURES ARE: /1/ 75 PERCENT SHELL WHEN THE MAXIMUM DENSITY IS THE CRITERION, AND /2/ AT LEAST 65 PERCENT SHELL WHEN THE TEXAS TRIAXIAL CLASSIFICATION IS THE CRITERION. THE FIELD STUDIES SHOW THAT A RELATIVELY HIGH INPLACE DENSITY WAS ACHIEVED DURING CONSTRUCTION, BUT A LOWER DENSITY WAS MEASURED AFTER THE ROADS WERE IN SERVICE FOR SEVERAL YEARS. /BPR/
