Contract 2 consisted of highway improvements to support The East Midlands Gateway development. The majority of the earthworks were located along the east side of the M1 between J24 and J24a, where a new embankment has been formed. The A50 eastbound will now have a direct slip road onto the M1 southbound, as opposed to using J24 as it is now.  Other works include build-outs around J24 and road realignments beneath the new rail embankment. The new A50 embankment required the diversion of the Derwent Valley Aqueduct. This high-pressure water main takes water from Ladybower reservoir in the Peak District down to Leicester. Following the new pipe installation, the backfill and overlying fill were undertaken with the absence of vibration. A significant area of the embankment footprint was founded upon an old tip facility. In consideration of costs and time, the option to use Dynamic Compaction was chosen over removing the made ground and re-engineering. Collins was involved in providing a 6C stone mat for Hydrock to undertake their High Energy Impact Compaction system on. Once the settlement had sufficiently diminished, the upfilling of the embankment commenced. All earthworks were placed in accordance with Hydrock’s specification. We were also involved with reinforced earth embankments around two culverts. The carriageways were treated with lime and cement to reduce the subbase depth.
