Groundwater may occur close to the surface or it may lie many hundreds of feet below. WebSub-surface drainage is used exclusively to control the moisture of all types of road s sub-grades. If the moisture that accumulates in the sub-soil is excessive, the road structure weakens therefore it is more necessary to control the moisture of the road sub-grade. Functions of sub-surface drainage: To control the moisture of road sub-grades.
