Associated Asphalt has completed resurfacing works along a 47-mile section of the M40 between Warwick and Oxford.
The contractor supplied and laid more than 35,000 tonnes of asphalt for UK Highways’ design, build, finance and operate contract, in conjunction with National Highways. The programme ran from 2 March until the end of August.
Overnight delivery
The works included targeted pavement repairs, with deteriorated surfacing removed and replaced with compliant pavement finished in 10mm Stone Mastic Asphalt. The material was manufactured using Clause 942 polymer-modified bitumen and HAPAS-accredited materials.
Associated Asphalt said the finished surface would provide durability, reduced road noise and lower surface spray. Overnight shifts were used to limit disruption to motorway users.
The company invested in an asphalt plant at Yarnton, Oxford, with annual production capacity of 100,000 tonnes. It said the plant supported security of supply and reduced vehicle movements by allowing material to be delivered close to the worksite.
Associated Asphalt has worked on M40 projects for UK Highways since 2015. Previous schemes include the strategic refurbishment of the 500-metre Loudwater Viaduct, deep construction maintenance between Junction 1 and Junction 1A, and maintenance around Junction 1A.
The contractor has also carried out emergency call-out repairs during the life of the contract. UK Highways’ current 30-year contract is due to end in 2027.
