Tarmac, the UK’s leading sustainable building materials and construction solutions company, recently geared up to successfully resurface a section of the Lydden Hill race circuit in Wootton, Kent.
The company was tasked with resurfacing the circuit’s cambered ‘Devil’s elbow’ corner and adjacent sections of the facility’s track,which regularly hosts international motoring events and is acknowledged as the birthplace of the sport of rallycross.
Using its experience from completing similar projects on other UK racing circuits including Brands Hatch, Tarmac created a unique and innovative paving solution specially designed to meet the track’s high durability requirements.
Phil Greenin, operations manager at Tarmac, commented: “The high-stress nature of a racing circuit meant that a standard asphalt product would not have been suitable for this project. We therefore proposed the use of a bespoke polymer modified bitumen (PMB) material, known as ‘Race Track 10’, which is much more resistant to the extremes of braking and cornering.”
Forward planning and careful coordination of the team were essential to ensure that the 240 tonnes of surfacing material was laid continuously in a single shift. This avoided there being any cold joints, which have the potential to allow water ingress that can lead to the asphalt breaking up and interrupt the smooth ride for vehicles tackling the demanding circuit.
Phil Greenin adds: “Timing and efficiency in a tight working window on the day was critical – we had to guarantee there would be no delays in the supply of the material. After planing off the old material and sealing any cracks, we laid the new surface in echelons to avoid creating any long joints. This prevented any weak spots and maximised the new surface’s robustness.”
The result of the thorough laying and compaction process was not only an even, high-quality finish, but a surface that will withstand the high demands and stresses of vehicles competing in professional racing series.
Pat Doran, Lydden Hill track owner and former four-time British Rallycross champion, said: “We’re really pleased with the quality of the recent resurfacing work and would like to thank Tarmac for the fantastic work they have carried out during the recent improvements.
“The FIA has since approved the work and commented that it was some of the best surfacing work they had seen to date. We are very grateful that the team was able to propose and lay a hard-wearing and durable material, which has created a smooth surface that will last for many years to come.”
