DEGRADATION OF GRANULAR EMBANKMENTS AND FOUNDATION MATERIALS
THERE ARE MANY AREAS IN THE STATE OF ALASKA WHICH CONTAIN MATERIAL OF QUESTIONABLE AND INFERIOR QUALITY FOR USE AS SUBBASE AND BASE COURSE MATERIAL DUE TO THEIR DEGRADING CHARACTERISTICS. THE GREAT MAJORITY OF THESE AGGREGATES WILL PASS PRESENT SPECIFICATION REQUIREMENTS FOR QUALITY AND, THEREFORE, A QUALITY TEST WHICH WILL SATISFACTORILY PREDICT DEGRADING CHARACTERISTICS IS BADLY NEEDED. THIS REPORT PRESENTS AN EVALUATION OF DEGRADATION TEST METHODS PRESENTLY BEING USED IN THE STATES OF OREGON, WASHINGTON, CALIFORNIA, IDAHO, AND ALASKA. THIS EVALUATION WAS BASED UPON' /1/ CORRELATION BETWEEN TEST RESULTS AND ACTUAL FIELD PERFORMANCE OF THE AGGREGATE, /2/ SIMPLICITY OF PROCEDURE AND REPRODUCIBILITY OF RESULTS, /3/ ABILITY TO BE ADAPTED TO FIELD USE, AND /4/ COST OF NECESSARY EQUIPMENT. A TOTAL OF 19 CONSTRUCTION PROJECTS WERE SELECTED, 4 OF WHICH WERE FIELD TEST SITES, EACH USING A DIFFERENT TYPE OF AGGREGATE. SAMPLES WERE SECURED AT THE SOURCE, AFTER PLACEMENT, AFTER 1-12 MONTHS SERVICE, AND THE FIELD PERFORMANCE COMPARED WITH THE DEGRADATION TEST RESULTS. IT IS RECOMMENDED THAT THE WASHINGTON DEGRADATION TEST BE ADOPTED FOR USE BY THE ALASKA DEPARTMENT OF HIGHWAYS. /AUTHOR/
