Abstract:This paper reports an investigation into the development of a compaction procedure for base mixes containing aggregates of 1 1/2" (38 mm) maximum size. The specimens were made in a manner similar to that given in ASTM Designation 1561-71, except that a 6" diameter mold was used instead of a 4" mold. The compaction procedure was developed using a mix in the middle of the gradation for a B-3 mix. Once an acceptable procedure was found, it was checked by making specimens using four different mixes. It was found that the procedure which gave generally acceptable results for one mix did not give acceptable results for the other mixes. Therefore, the adoption of a compaction procedure for basic mixes is not recommended at this time.
