IN-SERVICE DEGRADATION OF BASE COURSE AGGREGATES

THE RESULTS OF SAMPLING BASE COURSE AGGREGATES FROM CONSTRUCTED FLEXIBLE PAVEMENTS INDICATE THAT DEGRADATION OCCURRED DURING CONSTRUCTION, PRIMARILY DUE TO THE COMPACTION OPERATION. SUBSEQUENT SERVICE UNDER TRAFFIC FOR TWO YEARS HAS NOT PRODUCED SIGNIFICANT CHANGES OF GRADATION. THERE HAVE BEEN NO SIGNIFICANT INCREASES IN CLAY SIZE PARTICLES WITHIN ANY OF THE BASE COURSES SAMPLED, AND NONE OF THE BASE COURSES HAVE PRODUCED PLASTIC FINES. /AUTHOR/
