Compaction around Narrow Trenches and Boxes

Price: £12  

This report investigates the overall performance of reinstatements around boundary boxes, valve chambers and within narrow trenches using various backfill and bedding materials. The project has demonstrated that: - It is possible to achieve satisfactory reinstatement of these features using currently available materials and equipment. Pneumatic pole tampers have been found to be particularly effective in restricted areas around boundary boxes. Foam concrete as the backfill material minimises the chance and magnitude of settlement of the reinstatement. The performance of reinstatements using granular backfill material depends upon the compaction achieved, the bedding material used and the way it is installed. The widely held assumption that pea gravel is self- compacting is incorrect.
