Clearly the pipe needs to function as a conduit, as the whole idea of a pipe is to move liquid in a controlled manner and direction. Structural Fill See Section (A)(2)(g) of the Road and Bridge Specifications for complete requirements for backfill material. A trench at the edge of the pavement provides a cavity with the least resistance for water to flow and accommodate pavement drainage. 7) Install the longitudinal perforated pipe at the bottom of the trench without bedding material. Refer to VDOT Road and Bridge Specifications, Section Procedures (d) Post Installation Inspection for detail requirements and remediation procedures. 11) Backfill depth is at least equal to the diameter of the pipe. In a rigid pipe, this zone has zero effect on the load carrying capacity. The behavior of a material where the material deforms under load and does not go back to its original shape is called plasticity.
