PROJECT OVERVIEW
PROJECT CHALLENGES
The project was very challenging due to the proximity of the site access road and surrounding new builds.
Working on an embankment with large machinery required high levels of planning and safety measures in place such as Overbuild of the embankment to allow the equipment to stay min 1.0m from the edge of the embankment.
The soil had to be mixed with the Lime and allowed to Mellow (Flocculation) for min 4 hrs and then re-mixed prior to trimming and compaction.
Material is to be laid in accordance MCHW1 Clause 608 (Table 6/1) and Clause 616 and compacted in accordance clause 612 and Table 6/4. The method of compaction for Class 7A material is an “End Product” requirement. This requires 100% of maximum dry density of BS 1377 : Part 4 (2.5kg rammer method) or a dry density corresponding to 5% air voids at field mc, whichever is lower.
