AGGREGATE INDUSTRIES DEMONSRATES TEAM WORKING AT ITS BEST ON A30 CORNWALL BY-PASS

Bardon Aggregates, Bardon Contracting and Needham & Cullen - all Aggregate Industries businesses - are currently involved in the largest construction project of its kind in the South West, to build a new by-pass on the A30 at Goss Moor near Indian Queens in Cornwall.

The new seven mile stretch of dual carriageway will replace the single carriageway A30 trunk road between the Bodmin Bypass and the Indian Queens Bypass.

Working in association with main contractor, Alfred McAlpine, in excess of 350,000 tonnes of aggregates from Bardon Aggregates will be used for the scheme, including a high proportion of secondary aggregates. Over 200,000 tonnes of this total is coated macadam and to maintain supplies through this high demand period, a new Benninghoven mobile coating plant has been installed at Bardon Aggregates’ Melbur Quarry near Newquay, dedicated to supplying this project.

Jim Appleby, national commercial director, says: “The project is using an innovative road technique. A paver machine is laying the sub-base in one full-width pass to produce a high quality foundation layer. Needham & Cullen, part of Bardon Contracting and a specialist in this area, is utilising datum wires to control the paving machine and to ensure a greater level accuracy on the lower layer. This will ultimately produce a better platform upon which to build the road.

“The Bardon Contracting team is working behind the Needham & Cullen team to lay the road surface. All asphalt layers are being laid using an averaging beam to ensure better level control and to produce an excellent ride quality for users once the road is open to traffic. All in all it is a real team effort, and a great high profile project for us to be involved in.”
