Work involved large-scale earth and rock moving and high quality track surfacing, as well as quarrying and aggregate crushing/processing.
In total, 350,000 cubic metres of soil and rock were stripped and re-deposited on site in order to create the new profile for the 3.6km long, 12m-wide circuit. All materials excavated during construction remained on site. The establishment of an on-site quarry or ‘borrow pit’ reduced the cost of the project – and minimised disruption to the local area – by keeping an estimated 3,500 return truck journeys off the roads.
The construction of the track consisted of a:
The lower road base was produced on-site using a specialist foaming plant which cold- mixed raw aggregate, pulverised fuel ash, cement and foamed bitumen.
