What is the Coefficient of Subgrade Reaction?
In simple words, bitumen is a liquid that binds together asphalt. Asphalt-It is a mixture prepared by adding aggregates(sand, gravel, slag, crushed rocks) with appropriate binders like bitumen. Then it is laid down on-site to a decided level or thickness by a paving machine. Bitumen- This is the heaRead more

Bitumen- This is the heavy semi-solid hydrocarbon produced by the distillation of crude oil.

The coefficient of subgrade reaction is referred as the ratio between the pressure against the footing or mat and the settlement at a given point expressed as the coefficient of subgrade reaction which is defined as the ratio between the pressure against the footing or mat and the settlement at a given point which is expressed as ;
ks = q/S
where,
ks = coefficient of subgrade reaction
q = pressure on the footing or mat at a given point
S = settlement of the same point of the footing or mat in the corresponding unit of length
i. The value of k is independent of the magnitude of pressure.
See lessii. The value of s has the same value for every point on the surface of the footing.
