Soil Tests For Road Construction. Specific gravity tests You can either perform soil tests in the laboratory or onsite Following are the top four types of soil tests done prior to starting a road construction project 1 Moisture Content Test In this test the soil’s water is analyzed and represented as a percentage of dry mass.

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 size distribution moisture content determination specific gravity liquid limit and plastic limit tests.
What Soil Tests Are Required For Road Construction Scorpion
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 natural existing state of the soil b Specific Gravity Test The specific gravity of soil may be defined as the ratio of the weight of soil in the air of a given volume at a standard temperature to the weight in air of an equal volume of distilled water at the same stated temperature 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 particlesize ranges ie d Proctor Test Proctor test is a type of compaction test that is carried out to determine the compaction properties of soil In actuality this test is used for determining the mass of dry soil per cubic metre when the soil is compacted over a range of moisture contents providing the maximum dry density at the optimum moisture content.
Soil Tests for Road Construction Types, Purposes & Advantages
The compaction test (sometimes known as the Proctor test) is a laboratory method for determining the optimal moisture content at which a soil will achieve its maximum dry density These tests involve the compaction of soil at a known moisture content in a cylindrical mould of standard dimensions using a compactive effort of specific weight and frequency (specified in the relevant Standard).

for Road Construction Soil Testing Required Civil
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 are used for the calculation of soil properties such as degree of saturation The soil tests can be laboratory tests or insitu tests.
