Abstract
The safety and structural integrity of buried pipes are usually at risk from constructing loading and compaction of backfill materials. The backfill material should be strong enough to help resistance and redistribute loads so that the buried pipe remains unaffected. Due to the many problems associated with buried pipes, there have been multiple studies on the development of a sustainable backfill material. In this study, a Controlled Low Strength Material made of coal ash was considered as a buried pipe backfill material. To determine the feasibility and performance of this backfill material, a numerical simulation was conducted with the results confirmed by a field test. Results showed maximum settlement to be 2 mm with the elastic strain of the buried pipe to be about 0.006.
