THIS IS THE SECOND REPORT ISSUED UNDER A RESEARCH STUDY DEALING SPECIFICALLY WITH NONBLOATED SYNTHETIC AGGREGATES PRODUCED FROM NATURALLY OCCURRING CLAYS. THE FIRST REPORT DESCRIBED THE RESULTS OF A LABORATORY INVESTIGATION THAT INDICATED THAT MOST (IF NOT ALL) HIGHLY PLASTIC SOILS COULD BE USED TO PRODUCE HIGH-QUALITY SYNTHETIC AGGREGATES. THE PRESENT REPORT DESCRIBES A LATER INVESTIGATION DIRECTED TOWARD THE DEVELOPMENT OF ACCEPTANCE CRITERIA THAT CAN BE USED TO EVALUATE AGGREGATES OF THIS TYPE. THE INVESTIGATION INCLUDED THE PRODUCTION OF AGGREGATES IN THE ROTARY KILN, THE EVALUATION OF THESE AGGREGATES, AND A STUDY OF SEVERAL SYNTHETIC AGGREGATE FLEXIBLE BASES THAT HAVE BEEN IN SERVICE IN THE VICINITY OF HOUSTON, TEXAS, FOR SEVERAL YEARS. /AUTHOR/
