The Milestone 1 testing program included a 24-inch outside diameter (OD), 0.25-inch wall thickness (WT) pipe specimen in sand (24-inch Sand); a 12.75-inch OD, 0.5-inch WT pipe specimen in clay (12-inch Packed Clay); and a 24-inch OD, 0.25-inch WT pipe specimen in clay (24-inch Dumped Clay). Two different depths of cover (DOC) values of 2 and 3 feet were used in the testing and the test specimens were crossed by a variety of construction equipment, namely a dump truck, a bulldozer, a front loader, and a vibratory compactor. The testing was conducted at internal pipe pressures of zero, 550 and 750 psig.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367583346766,"sku":"132432","price":50.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/pr-218-104509-r02-field-validation-of-surface-loading-stress-calculations-for-buried-pipelines-milestone-3","provider":"PRCI Store","version":"1.0","type":"link"}
