Subsurface drainage design construction and maintenance

This document briefly deals with how moisture can enter a road structure and what damage may be caused to the structure by the entry of water. It then deals in considerable detail with the basic mathematical techniques that may be used to design a subsurface drainage system to either prevent or control moisture movement within the road structure. Guidelines for the selection of granular filter material and filter fabrics are given. A summary of techniques used in rural New South Wales and guidelines to assist construction personnel are also given. The basic maintenance operations are described and a maintenance management system is introduced (a).
