The challenge

By 2019, the surface of the Silverstone track was badly in need of replacement. However, this project was significantly more complex than a standard road resurfacing. Before work could commence, the existing Silverstone surface had to be removed. Then, a new surface, optimised for water run off while being resistant to the lateral loads and extreme braking and cornering in modern motorsports, had to be put in place ahead of the British Grand Prix on July 14.

The solution

Resurfacing Silverstone required a new, bespoke asphalt mix, designed to deliver excellent levels of grip and withstand the stresses of professional racing.

Work on the new surface commenced on June 10 following months of meticulous planning and materials trials. Tarmac used state-of-the-art technology to complete this project, including 3D scanning machines to identify bumps in the existing track. This helped to improve circuit gradients, enhance drainage and eliminate bumps in the surface.

Tarmac’s expert team used automated paving technology to enhance and improve quality during the laying and compaction of the asphalt. The new surface was laid by three paving machines in close formation to deliver a seamless, joint-free surface across the width of the track.

To address the logistical challenges of delivering material to the jobsite, thermometers, sensors and GPS tracking systems fitted to the construction plant provided real-time data, allowing the team to control, with precision, the installation of the new circuit.

The 87,000m2 surface was milled in just three days and two nights. The new surface, which included 18,000 tonnes of recycled materials, was completed on 30 June 2019, ready for the British Grand Prix F1 race at this internationally famous circuit.
