A67 Boldron Junction

The innovative Plastipave® product range manufactured and supplied by Tynedale Roadstone utilises end-of-life plastic waste streams, preventing them from going to landfill or incineration. Plastipave Thin is produced to the same standards as a Clause 942 material and benefits from all the technological advantages of a Thin Surface Course System whilst incorporating ‘waste’ addition to the mix.

The material is suitable for laying on Local Authority and Trunk Road Network schemes. The texture of the material is obtained from the interlocking nature of the coarse aggregate and there is no requirement for addition of pre-coated chippings to obtain skid resistance. This allows the materials to be specified in locations where the use of a chipping machine is not suitable or would require extensive road closures.

The negative texture also reduces noise produced from traffic tyres which is ideal for urban situations where noise pollution needs to be minimised.

Rainton Construction undertook structural patching and resurfacing to a 1.2 km section of carriageway on the A67 which links the Market Town of Barnard Castle and the A66 Trunk Road at Bowes.

The original specification was a traditional 60mm of HD binder for the structural patching areas and a 50mm hot rolled asphalt surface course with 68 PSV pre-coated chippings. This posed a safety risk as there was no hard verge or footway to allow the chipping machine to travel.

The surface course was modified and the team used Plastipave® Thin, removing the requirement for pre-coated chippings while providing the required skid resistance for traffic. The added benefits of incorporating single use plastic waste meant overall we diverted 1.5 tonnes of rubber and plastic waste from landfill, saving 5.3 tonnes of CO₂.
