Description

An exhaustive review of data on compaction equipment and compaction operations that were available in 1960 are presented. A brief review of the early history of soil compaction and some of the fundamentals of soil mechanics that are applicable to compaction processes are mentioned. Also included are tabulated data on the state highway department specifications for governing compaction requirements and compaction equipment.

The most significant aspect is the extensive amount of available data on full- scale field compaction that has been summarized. These data include results from full-scale field tests using 3-wheel power rollers, sheepsfoot-type rollers, pneumatic-tired rollers, vibratory compaction and tamping compactors. For each type of compacting equipment, various factors such as effects on number of passes, effect of weight of roller, depth of compaction, density produced, etc. Have been presented. In most cases comparisons between various types of equipment are presented.
