A trench had been cut, excavated to install services then backfilled before our arrival on site. We compacted the sub-base and added 150mm of roadbase which was compacted and waterbound forming a strong basecourse which can withstand heavy duty traffic. The trench was then sealed with asphalt (also called bitumen or hotmix) which ties in flush to the surrounding existing bitumen carpark. One of the benefits of bitumen / asphalt over concrete is that it can be easily repaired and driven on immediately so work sites do not need to be shut down for long (no waiting for cure times). Yellow sand has been sprinkled on this completed job to protect it from unsightly tyre scuff marks.
