By 2019, the surface of the Silverstone track was badly in need of replacement. However, this project was significantly more complex than 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 extreme stresses of modern motorsports, had to be put in place ahead of the British Grand Prix.
Resurfacing Silverstone required a new, bespoke asphalt mix, designed to deliver excellent levels of grip and withstand the stresses of professional racing. State-of-the-art technology, including 3D scanning machines to identify bumps in the existing track, was used to control the production, delivery and installation of the new world-class surface.
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.
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.
