PREDICTION OF ROLLER COMPACTION EFFICIENCY

The usual procedure for specification of roller equipment, lift thickness, and number of passes to compact a soil fill material of prescribed water content to an optimum density is one that heretofore has traditionally depended on empirical relations and similitude modeling--the use of laboratory-derived test data on soil compaction. In this study, soil compaction under a towed roller is predicted by using the finite-element method (FEM) of analysis. The format of the analysis encompasses the transient loading nature of the tire or roller. By expressing the compaction effort exercised by the rigid roller in terms of the amount of compaction energy required to produce a resultant unit deformation of a particular soil lift thickness, FEM analysis allows one to obtain an evaluation of the influence of soil type, lift thickness, water content, and number of passes on compaction efficiency. In addition, the format for analysis is structured to incorporate compaction of additional soil layers through a layered soil-analysis procedure. The analysis of soil compaction efficiency is supported with corresponding laboratory experiments that involve wheel tow-bin tests. (Author)
