The conventional pavement underdrain system consists of a perforated pipe collector, a gravel layer around the pipe to prevent its clogging, and a sand filter layer around the gravel to prevent migration of the natural soil from entering the gravel.... A major use of fabrics has been to vastly alter this type of underdrain system. Shown in Figure 5.2 (b) are the schematic diagrams of a replacement of the conventional method using a fabric-wrapped stone aggregate (with or without the perforated pipe) placed directly in an excavated trench. 1, record 1, English, - pavement%20underdrain%20system
