Purpose of test To determine the specific gravity of soil fraction passing 4.75 mm sieve by pycnometer. Use of specific gravity value The knowledge of specific gravity is needed in calculation of soil properties like void ratio, degree of saturation etc. Definition Specific gravity G is defined as the ratio of the weight of an …
Soil Testing Required for Road Construction Generally, when it come to construction on soils, tests should be performed to understand the nature of soil that the building is going to be constructed on. In this article, the basic tests required for the construction of roads and highways are briefly mentioned. Common test are: Soil classification, particle …
In this article named “Standard Proctor Compaction Test”, the details and procedures of proctor test are described. Introduction For construction of highways, airports, and other structures, it is often necessary to compact soil to improve its strength. Proctor (1933) developed a laboratory compaction test procedure to determine the maximum dry unit weight of compaction of …
