AGGREGATES FOR HIGHWAY BASE COURSES IN CALIFORNIA

A DISCUSSION OF THE HISTORICAL BACKGROUND OF HIGHWAY DESIGN CONCEPTS AND A REVIEW OF THE PERFORMANCE REQUIREMENTS OF BASE COURSE MATERIALS IS PRESENTED. A DESCRIPTION IS GIVEN OF METHODS OF EVALUATING AGGREGATE PROPERTIES, INCLUDING TESTS DEVELOPED BY THE CALIFORNIA DIVISION OF HIGHWAYS, THE SAND EQUIVALENT AND DURABILITY INDEX, TO EVALUATE POTENTIAL DETRIMENTAL EFFECTS FROM CLAY FINES. THE CONSERVATION AND IMPROVEMENT OF AGGREGATES IS DISCUSSED AND EMPHASIS IS PLACED UPON THE IMPORTANCE OF MAINTAINING A PROPER BALANCE BETWEEN BASE COURSE PERFORMANCE AND COST. /RRL/
