For the purpose of calculation, buried installations of PE pipe can be separated into four egories depending on the depth of cover, surface loading, ground water level, and pipe diameter.
Main Road Loading This is the heaviest loading which the pipe can expect if laid beneath any major highway in the UK. This loading egory tends to stick to the old BS 5400 2 loadings as most published tables where compiled
Properly installed HDPE corrugated pipe can withstand AASHTO HS 25 loads with a minimum 1 ft (0.3 m) of cover for pipe up to 48 in diameter (1200 mm), or 2 ft (0.6 m) of cover for larger pipe diameters.
