PR-218-174512-R01 Full-Scale Surface Loading Testing of Buried Pipes

In 2015, Kiefner and Associates, Inc. (Kiefner) completed the ENV-6-1 project "Field Validation of Surface Loading Stress Calculations for Buried Pipelines" in which Kiefner monitored three buried pipe test segments at the Berne Station in Ohio to measure circumferential and longitudinal stresses due to heavy equipment crossing over the segments. This ENV-6-2 study "Full-Scale Surface Loading Testing of Buried Pipes Vibratory Compactor and Temporary Crossing" ionducted in the same location and on the same three pipeline specimens. The objective of this project is to develop surface loading criteria for pipelines with shallow burial depth under temporary crossings (e.g. mat, bridge, or steel plate) and pipeline subjected to dynamic loading from a vibrator compactor.
