Scope of Study: The purpose of this report is to study soil compaction in both the field and the laboratory. The main part of this report is a discussion of soil compaction from the construction point of view, including discussion of field compaction equipment and factors affecting the compaction of soil in earthwork construction.

Compaction is a mechanical process in which an earthen material is made more dense.The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading.Volume changes are incurred as a result of a reduction in the quantity of air voids-water content remaining constant.Since it is impractical to squeeze out all the air, the as-compacted condition is a partly saturated one.

A Harvard miniature compaction device was used to determine the optimum moisture content (OMC) and maximum dry unit weight (MDW) of the ash samples. Samples were prepared at water contents ranging from 10-50% and compacted in three layers (25 tamps per layer). Water content measurements were taken from the middle of each sample after extrusion. To identify error associated with operator variability which has been discussed as a major flaw of using a Harvard miniature compaction device (Araújo Santos et al. 2019), multiple compaction tests were performed on a single sample of biomass fly ash as a proxy. Results indicated that the operator had consistent application of compaction force, as MDW values had a percent error of less than 1% compared to the average value. For wildfire ash samples prepared at water contents nearing the liquid limit, compaction by hand-tamping was necessary to prevent bearing capacity plunging failure.

Compaction refers to the densification of shallow soil layers by rollers. Depending on the soil type and the size of the project, different compactors are used. Laboratory tests are used to establish the characteristics of the soil to be compacted, to establish the target values to be achieved in the field, and to write the specifications for field work. This chapter provides a brief summary of the compaction process and the compaction curve associated with laboratory tests. Field tests are used to verify that the compaction work has been done according to specifications. The field tests are divided into classic tests and new tests. Traditional rollers may have an energy capacity that is too low compared to the need. This might be the case for breaking the interparticle bonds of collapsible sands, for example. Impact compaction rollers were developed to alleviate this type of problem.
