A soil sample was taken from a proposed cut area in a highway construction project and sent to a soils laboratory for a compaction test, using the Standard Proctor compaction procedure. Results of the test are as follows: Maximum dry unit weight = 112.6 Ib/ft3 Optimum moisture content = 15.5% The contractor, during construction of the soil em-bankment, achieved the following: Dry unit weight reached by field compaction = 107.1 Ib/ft3 Actual water content = 16.0% Determine the percent compaction achieved by the contractor.

Soil Compaction Test

Soil compaction is the major area of geotechnical engineering. Soil is composed of multiple pores present on its surface, while the soil is mainly composed of gravel, sand, rocks, etc. The arrangement of these rocks and gravels is such that they build up voids (spaces) between them, which allows spaces for the roots of the plants and crops to spread and absorb the required amount of nutrients. Soil compaction is a major problem primarily caused by human activities, micro-organisms, and other multiple factors.
