Abstract
In this study, field tests were performed to evaluate the stability of pre-insulated pipe during the compaction operation and to recommend an alternative backfill material. Three types of natural sand (fine-grained and medium-grained, coarse-grained sand), crushed sand and two types of gravel (10 mm, 20 mm) were used as backfill material in the field tests. Field tests were performed to determine the behavior (earth-pressure and deformation, installation damage) of the pre-insulated pipe due to variation of different types of backfill material. Based on the evaluation and comparison of field test results, it was determined that crushed sand is the most suitable back-fill material that can be used as an alternative for medium grained sand for pre-insulated pipes with respect to the engineering behavior and material supply.
