CORNISH CHALLENGE

The tip of the Cornish peninsular is becoming more accessible due to a number of road schemes designed to remove bottlenecks. Environmental relief will be provided for a number of towns and villages which are very congested by tourist traffic during the summer. This article describes one such scheme, the A30 Trunk road Plusha to Bolventor improvement, upgrading the existing single carriageway to a dual carriageway with grade separation being used at nearly all the junctions. Design has been carried out using the MOSS computer aided design system. Ground conditions vary from granite at the western end to shales in the east and the contract has been designed to make the maximum use of material. Unsuitable material will be used for landscaping. Blasting and breaking has been used to excavate considerable amounts of granite to form a 10m deep cutting at the western end of the scheme. A short length of the site is being used for a trial to develop a multi-purpose composite road pavement for Europe (Ecopave). A high strength concrete road base is being laid which it is hoped will avoid the formation of reflective cracking of the wearing course. (TRRL)
