The dry and saturated unit weights of the soil are 110 lb/ft 3 and 130 lb/ft 3 , respectively.BULLETINMINIMUM COVER HEIGHT Minimum cover height for 4-inch to 48-inch (100 mm to 1200 mm) diameters shall be at least 1 foot. Minimum cover height for 60-inch (1,500 mm) diam-eter pipe shall be at least 2 feet. Minimum cover height is measured from the crown of the pipe to the bottom of a flexible pavement section or to the top of a rigid pavement section.By how much does the thermal expansion coefficient of HDPE Maybe it helps you that, when a HDPE pipe is buried in the soil, the temperature of the system is more stable than an above ground pipeline, which needs great expansion joints.
