Types of soil tests for a road construction project require the site investigation to be carried out to understand the soil profile. For road construction works, the properties of soil at subgrade level are required. The common soil test for road construction includes classification of soil, particle size distribution, moisture content ...

- a. Moisture Content Test. The moisture content of the soil is the amount of water it contains and is expressed as the percentage of dry mass. The test for determining the moisture content of the soil is vital for assessing the existing natural state of the soil.
- b. Specific Gravity Test By Pycnometer Method. The specific gravity of soil may be defined as the ratio of the mass of solids to the mass of an equivalent volume of water at 4ºC.
- c. Particle Size Distribution Test. The particle size distribution of soil may be defined as the proportion of the dry mass of soil distributed over specified particle-size ranges, i.e., gradation of soil.
- d. Proctor Test. The Proctor test is a type of compaction test carried out to determine the compaction properties of soil. In actuality, this test is used for determining the mass of dry soil per cubic meter when the soil is compacted over a range of moisture contents providing the maximum dry density at the optimum moisture content.
Nov 15, 2023 · During construction, soil tests serve as a critical tool for quality control. Regular testing ensures that the actual conditions on-site align with the expected behavior predicted during the design phase. Adjustments can be made in real-time, guaranteeing that the constructed road meets the specified standards.

Liquid limit and plastic limit tests (Atterberg test) Moisture content test. Compaction test (Proctor’s test) Classification of soil. California Bearing Ratio (CBR) Test. California Bearing Ratio test can be conducted in ...
Here, the particle size distribution test helps determine the extent of soil particles and predicts soil water movement once the road is completed. 4. Compaction Test. The compaction test is also known as the proctor test, where the mass of dry soil per cubic meter is determined when the soil is compacted on a small surface.
For road construction works, the properties of soil at subgrade level are required. The common soil test for road construction includes classification of soil, particle size distribution, moisture content determination, specific gravity, liquid limit and plastic limit tests. Moisture content, particle size and specific gravity tests on soils ...
