1. SECTION A SOIL MECHANICS
a) The aim of the Proctor test is to determine the optimum water content at which a given soil type can achieve its maximum dry density when compacted with a specific effort. This information is essential for controlling compaction in the field to achieve desired engineering properties.
b) Optimum water content is the specific moisture content at which a soil achieves its maximum dry density under a given compaction effort. At this water content, the soil particles are sufficiently lubricated to allow for dense packing, leading to the highest possible density for that compaction energy.
c) Soil compaction is the process of increasing the density of soil by reducing the air voids within it, typically
