Buckinghamshire Council is trialling the limited use of recycled plastic in road resurfacing.

Although trialled successfully in Europe, these are the first trials of their kind in the UK. During the trial Buckinghamshire Council will be working with UK based company Roadfill Ltd. The trial involves the use of the recycled plastic product ‘Roadworx’.

Two small trial patches of road, one on the busy A40 Oxford Road in Denham and the second on a quieter road, Orchard Way in Holmer Green have now been laid. The Highways team will be closely monitoring how the material performs alongside more traditional materials.

The recycled plastic from waste is incorporated into the asphalt mix and used in the road surface layer, with the aim of creating a stronger, more durable and reliable road, whilst retaining sufficient elasticity to reduce the formation of cracks and potholes.

Although the plastic makes up just 0.2% of the material used to resurface the road, on just the relatively short trial section at Orchard Way (280m length) the plastic material used equates to 16,000 recycled 500ml plastic bottles, with approximately 0.5 tonnes less bitumen needed than in traditional asphalt.

Steven Broadbent, Cabinet Member for Transport at Buckinghamshire Council, said: ‘We will be monitoring these stretches of road carefully. The two trials will enable us to test the performance and longevity of the road surfaces over an initial 12-month period.

If the results are positive, we may then consider further sites, as well as monitoring the original sites for a further four years to check how they hold up over a longer period of time.
