The A14 improvement scheme will feature 21 miles of new multi-lane carriageway
Construction and infrastructure provider Aggregate Industries has laid its millionth tonne of material on Highways England’s A14 Cambridge to Huntingdon Improvement Scheme.
The company says the landmark - achieved in collaboration with the A14 Integrated Delivery Team - coincides with the UK project’s designated, on-site asphalt plant producing its 350,000th tonne for use on the improvement scheme.
In addition, 150,000 tonnes of asphalt has been provided from Aggregate Industries’ plants at Bardon Hill, Peterborough and Purfleet, and in excess of 500,000 tonnes of cement bound granular mixtures (CBGM) has been manufactured and placed.
When completed the A14 Cambridge to Huntingdon Improvement Scheme will feature 21 miles of new multi-lane carriageway, laid utilising local primary and secondary aggregate supply sources.
The types of asphalt Aggregate Industries utilised on the project include its 10mm SuperThin asphalt which is claimed to reduce the noise level by 7.8db(A) when compared with traditional hot rolled asphalt (HRA). The asphalt is designed to meet stringent noise restrictions where the scheme passes through built-up areas.
Aggregates Industries says the works have presented challenges. In particular, the summer has seen the completion of some very complicated traffic switches, with the 17th and 18th of August alone demanding 5,600 tonnes of asphalt be continually mixed, transported and placed to transform the Bar Hill Junction.
Paddy Murphy, MD of contracting at Aggregate Industries, said: “It is a great achievement to have laid our millionth tonne of material on Highways England’s A14 Cambridge to Huntingdon Improvement scheme, currently the UK’s largest and most prestigious major infrastructure project.
“Reaching this milestone was made possible by working safely and in complete collaboration with the A14 Integrated Delivery Team, and the completed carriageway upgrades will be of great benefit to the local area.”
