Abstract:
Soil compaction is one of the most important aspects of any earthwork construction. Compaction improves the engineering
properties of the fills. Nearly all compaction specifications are based on achieving a certain value of dry unit weight (γd). During
construction, the geotechnical engineers measure the unit weight of compacted soil in the field to verify the contractor’s
compliance with the requirement. This paper is a project study of road construction project “Road Zia Colony to Mirpur
Cantonment”. Soil samples were collected from five different locations. In situ dry density was obtained by Sand Cone Test from
each location. The laboratory tests (Standard Proctor Test) were carried out to find out the dry density for each sample. The
maximum dry density in relation to moisture content was obtained. Relative compaction (CR) of soil at each location was then
calculated to the soil compaction of the said road project.
