Polyethylene Pipes for Use as Highway Culverts
The first Colorado Department of Transportation (CDOT) installation of polyethylene pipes for culvert use was in 1988, on SH 50, north of Olathe. Five to ten feet of well compacted in-situ material was used as backfill. No obvious deflections occurred in the pipe during or after construction, or as a result of in-service live loads. After three years of service, the pipes have not cracked, melted, or worn, and are in good overall condition. One culvert, however, burned for about ten feet into one end as a result of the ignition of sawdust that had collected in it from a nearby sawmill. This section of pipe was replaced. A literature search found that with proper backfill, loads of 100 feet of fill could safely be supported. Some pipes, however, were reported to have deformed excessively even with small loads. These were for the most part 12 inch and 15 inch diameter pipes that had a thinner wall, and were not well supported. The main advantanges of polyethylene pipes are: light weight, easier installation, corrosion resistance, and relatively good aesthetic qualities.
