A summary of studies on compaction of asphalt concrete, and a resume of present work on AC compaction methods is presented. Some of the primary factors influencing compaction of asphalt paving mixtures were found to be temperature of the mixture at various phases of compaction, air temperature, gradation and shape of aggregates, asphalt content of the mixture, and weight of rollers and number of coverages. A discussion of the water permeability test as applied to compaction control of asphaltic pavements is presented. The use of nuclear gages for compaction control of AC, both backscatter and direct transmission types, is discussed. A typical field study of AC rolling is included. Thick lift compaction is covered by a description of a thick lift test section of asphalt concrete, approximately 6,000 feet in length. Conclusions as to temperature effects, types of compaction equipment, effects of additional rolling and compaction control tests are given. (Author)
