Title 210 – Engineering Field Handbook (210-650-H, Amend. IL66, August 2013) IL17.D-1 D. Minimum and Maximum Fill Over Pipes The following tables provide acceptable minimum and maximum earthfill heights over the pipe for several different types of pipe
HDPE pipe shall not be used in appliions where the depth of cover exceeds 10 feet. The minimum cover shall be 18 inches. In appliions where 18 inches of cover can not be obtained, cover of 12 inches or more may be allowed with Engineer approval.
Maximum cover of 50 ft, with or without traffic, rail, or surcharge loading; minimum cover of at least one diameter or 18-in., whichever is greater. Earth pressure applied to the pipe is determined using the prism load (geostatic soil stress).
