Question

what leads to drying up of soil?

Answer 1

Modification/dry up is closely related to Soil Stabilization. Each process involves the uniform application and blending of a material with site soils in order to enhance their engineering properties through chemical and physical alteration. The distinction between the two is that while stabilization drastically increases the shear strength of a material, (reducing soil plasticity and swelling and increasing load bearing capacity such that it can be incorporated into a pavement's structural design) modification/dry up is mainly a means to reduce the moisture content of a soil and increase its workability, expediting construction that would otherwise be delayed by rain or spring thaws.
