Road recycling in the spotlight

UK local authorities are increasingly focusing on sustainability, with the Local Agenda 21 specifying a target level of 10% for the use of recycled or secondary materials in suppliers' products. The implications for the aggregates and asphalt industries are examined. Tarmac has completed the biggest road-recycling contract carried out in the UK on the A38 in Devon. During the project to resurface 12 km of road between Plymouth and Exeter, Tarmac produced 100,000 tonnes of road planings, of which 70,000 tonnes were recycled as 'foam-mix' for use in the reconstruction of the carriageway. The contract was carried out for the Highways Agency. Traditional planing equipment was used on site, with mobile equipment for crushing and grading the planings located at the nearby Linhay Quarry. The 10-28 mm planings were used to produce FoamMaster. The recycling mix was performance tested to ensure that it complied with TRL 611 '2004- a guide to the use and specification of cold recycled materials'. Tarmac has invested in the acquisition of the road-planing company National Road Planing Ltd and in new mobile recycling plant and equipment. (A)
