Abstract:This report documents a review of nationwide practices with regard to recommendations for fill heights over high density polyethylene (HDPE) pipes. Another item of interest to the investigation was typical use of HDPE pipes by various agencies. The bulk of the report’s information, which is related to HDPE pipe diameter, minimum and maximum fill heights, backfill materials, and other pertinent items, was gathered via telephone interviews with the concerned staff from various state highway agencies. Limited information was also obtained by contacting the industry representatives, pipe manufacturers, and reviewing documents from American Association of State Highway and Transportation Officials (AASHTO) and American Society for Testing and Materials (ASTM). All 50 state agencies were contacted for information, of which 47 responded. In addition, a survey questionnaire was developed and sent to selected personnel in five state agencies to gather more in-depth information. Based on this information, recommendations for maximum fill heights and recommended use of HDPE pipes in roadways were developed for consideration by the Arizona Department of Transportation.
