Key Heathrow Airport link road undergoes repair

Hounslow Highways, working together with other Eurovia UK divisions including Surfacing, Contracting, Specialist Treatments and Euromark, has completed road reconstruction works on Stanwell Road West - one of the London Borough of Hounslow’s main link roads to Heathrow Airport. A large number of heavy goods vehicles and buses using the 80km/h dual carriageway results in significant loading on the road. Initial plans were to give Stanwell Road West complete reconstruction from the foundation level upwards

Effective planning ensured a major road link to Heathrow Airport was repaired quickly and efficiently
Hounslow Highways, working together with other 3281 Eurovia UK divisions including Surfacing, Contracting, Specialist Treatments and Euromark, has completed road reconstruction works on Stanwell Road West - one of the London Borough of Hounslow’s main link roads to Heathrow Airport.

A large number of heavy goods vehicles and buses using the 80km/h dual carriageway results in significant loading on the road. Initial plans were to give Stanwell Road West complete reconstruction from the foundation level upwards due to rutting and reflective cracking. However extensive tests carried out in collaboration with Test Consult and 2374 Jean Lefebvre UK revealed that there were no issues with the concrete carriageway base.

A new solution was designed by Jean Lefebvre UK to treat cracks and joints in the concrete and allow for Flexiplast to be applied on top of a regulating course prior to the installation of new asphalt layers.

The works were not without challenges. With a high pressure fuel line for the airport crossing the road, advanced line searches and meetings with BPA (British Pipeline Authority) technicians were required to allow the work to be carried out safely. And as Flexiplast has to be laid in dry weather, it was necessary to ensure the timings for each stage of the works were exactly right.

Crew flexibility was also tested when a collapsed sewer in nearby Hatton Road created a diversion route along Stanwell Road West. A different diversion had to be arranged and was managed by taking out a traffic island and a streetlight on Hatton Road.

    A novel dual-layer concrete paving technique has been used on jobsites in Germany on the country’s high-speed Autobahn network This technique allows the construction of a strong and durable roadway structure able to cope with heavy traffic loads and offer a long working life. In four German states, Wirtgen SP-1500 slipformers have been employed by four different contractors to carry out dual-layer paving. The method allows a noise-reducing, non-skid exposed aggregate surface to be placed over a bottom
