Abstract:
Tests were conducted at the U.S. Army Engineer Waterways Experiment Station to determine the effectiveness of vibratory compaction rollers in the compaction of zero-slump portland cement concrrete pavements. It was determined that the rollers were very effective in compacting the dry-mix concrete and that the strrength propertie, compressive strength and flexural strrength, weree somewhat higheer than would have been obtained with a conventional mix of the same cement content having a slump in excess of 1 inch. The surface smoothness, surface texture, and riding quality of the pavement were considered adaquate for weearing surfaces of secondary roads and streets, haul roads, service entrances, tank trails, ect., and as a base for any pavement system. Indications are that considerable cost reductions in the construction of portland cement pavements can be realized by usse of dry (zero-slump) concrete mixtures placed and spread by baase course or asphalt spreaders and compacted with heavy vibratory rollers.
