(Rationale: To update the specification to comply with performance specification requirements. The PE drainage tubing was deleted based on a national study of edge drainpipe, including some in Missouri, which questions the effectiveness of the product. Revisions include format changes to comply with new policy.)
08/14/03 - On Sec 1013, our teams rebuttal to comments regarding the exclusion of tubing was too harsh and should have been backed up by findings from the FHWA document FHWA SA-98 - 044 Video Inspection of Highway Edgedrain System. Don Hillis voted to approve this section.
