Soil stabilization deals with physical, physicochemical and chemical methods to make the stabilized soil serve its purpose as pavement component material.
Soil Compaction
COMPACTION & ROLLER REQUIREMENT FOR EMBANKMENT AND SUBGRADE
Compaction of soils required for different types materials for embankment and subgrade are shown here based on IS:2720 – part-8. Following table shows the relative compaction for different soil types: Sl. No. Type of work / material Relative compaction as percentage of maximum laboratory dry density 1 Subgrade and earthen shoulders Not more than 97(…)
SOIL MOISTURE CONTENT-DRY DENSITY RELATIONSHIP
The relation between moisture content and dry density of a soil at a particular compaction energy or effort is shown in Fig. 1. Fig.1: Water-content and dry density of soil When water is added to dry soil, it helps in bringing the solid particles close by coating them with thin films of water. At(…)
FACTORS AFFECTING COMPACTION OF SOILS
The dry density of the soil is increased by compaction. The increase in the dry density depends upon the following factors: Water Content: At low water content, the soil is stiff and offers more resistance to compaction. As the water content is increased, the soil particles get lubricated. The soil mass becomes more workable and(…)
BACKFILLING, CONSOLIDATION & COMPACTION
Preparation The ground over which the filling has to be done should be cleaned off all grass, loose stones, rubbish of all kinds etc. If there is water in the area, it should be pumped or bailed out. If the plinth depth doesn’t exceed 45cm above ground level and if the exposed ground is B.C.(…)
COMPACTION OF SOILS
Compaction means pressing of soil particles close to each other by mechanical methods. Air during compaction is expelled from the void space in the soil mass and therefore the mass density is increased. Compaction is done to improve the engineering properties of the soil. Compaction of soil is required for the construction of earth dams,(…)
