Secial care 0or exible ave$ent onexansive soils
Expansive soils swell very little when compacted at low densities and high moisturebut swell greatly when compacted at high densities and low moisture. Hence, wherethe probability of moisture variation in the subgrade is high, it is expedient tocompact the soil slightly wet of the field optimum moisture content (+2 per cent)determined on the basis of a field trial.
Experience shows that generally, it is not practicable to compact expansive soils atOMC determined by Laboratory Proctor Test. It is, therefore, necessary to study its field moisture density relationship through compacting the soil at different moisturecontents and under the same number of roller passes.
A minimum density corresponding to 95 per cent of the standard proctor densityshould be attained in the field and recommended moisture content should be. 1-2 percent wet of optimum moisture content.
Blanket Course
•
An impermeable blanket course of at least 225 mm thickness and composed ofcoarse/medium sand or non-plastic moorum having PI less than five should beprovided on the expansive soil subgrade as a sub-base to serve as an effectiveintrusion barrier. It must have very low permeability. The blanket course shouldextend over the entire formation width.
• Alternatively, lime-stabilized black cotton sub-base extending over the entireformation width may be provided together with measures for efficient drainage of
the pavement section.
