For rigid pipe such as concrete pipe and AC pipe, the pipe will break if unsupported since the pipe cannot flex in response to loads. Depending on the appliion and pipe strength, various degrees or classes of bedding with a load factor of 2.2 can provide twice as much load carrying ability as Class D bedding with its load factor of 1.1 (i.e. 2.2 = 1.1 X 2).
Bedding - In addition to bringing the trench bottom to required grade, the bedding levels out any irregularities and ensures uniform support along the length of the pipe. Haunching - The backfill under the lower half of the pipe (haunches) distributes
