With a firm and level sub-grade established, the next step in the process of the cycleway was the construction of the sub-base. This required importing several tonnes of crushed rock which was laid and compacted using a roller.
Sub-base compaction
This then acted as a capping over the sub-grade soil allowing us to traffic site plant to lay the concrete edging kerbs. These were bedded on a lean-mix concrete base to ensure they were adequately supported both in the construction phase and the final scheme.

Further crushed stone was then imported and laid to the final sub-base formation level and compacted ready for the “fun” part – the roadbase. The only thing more enjoyable in the construction industry than watching concrete being poured is seeing (and smelling) hot Tarmac being laid.

Excellent. Do these blogs relieve you of your duty to write up weekly site progress reports?
