Field Dry Density (Sand Replacement Method)

This document summarizes the results of a field dry density test conducted according to IS:2720 standard P-16 from 2015. It provides the details of 10 separate tests measuring the weight and density of compacted soil samples taken from various locations and depths within a layer. The degree of compaction is calculated for each test and ranges from 97.23% to 98.71% compaction, meeting or exceeding the required compaction standards for the material. The reviewer has marked the testing as passing.
