ASTM International’s concrete pipe committee ( C13 ) has approved a new standard that will help in manufacturing circular concrete pipe that is installed using pipe jacking techniques. The type of pipe covered by the new standard is typically used to convey sewage, industrial wastes, stormwater, or utilities. Engineers, precast concrete pipe manufacturers, and jacking contractors will be the…
