FACTORS INFLUENCING THE DURABILITY OF AGGREGATES

CALIFORNIA'S DURABILITY TEST WAS EXAMINED FOR POSSIBLE IMPROVEMENTS THROUGH MODIFICATION OR PROCEDURAL CHANGE. PAST PERFORMANCE OF THE TEST PROCEDURE HAS BEEN EVALUATED BY MEANS OF A FIELD SAMPLING PROGRAM, ACCELERATED DEGRADATION TESTS IN THE LABORATORY, AND CORRESPONDENCE TO DETERMINE EXPERIENCE THROUGHOUT CALIFORNIA'S ELEVEN HIGHWAY DISTRICTS. A DISCUSSION ON EXTENDED USE OF THE DURABILITY TEST IS INCLUDED, AND A REVIEW HAS BEEN MADE OF POSSIBLE ALTERNATE DURABILITY TESTS. THE GENERAL CONCLUSION WAS REACHED THAT CALIFORNIA'S DURABILITY TEST HAS BEEN VERY EFFECTIVE AND NO MAJOR MODIFICATIONS WERE RECOMMENDED. /AUTHOR/
