A67 Boldron Junction

Project Overview

Rainton Construction undertook structural patching and resurfacing works on a 1.2 km section of the A67 carriageway connecting Barnard Castle and the A66 Trunk Road. The project aimed to improve the road’s condition while prioritising safety and sustainability.

Challenges

The original specification called for a traditional 60mm HD binder for structural patching and a 50mm hot rolled asphalt surface course with 68 PSV pre-coated chippings. However, the lack of a hard verge or footway posed a safety risk for the chipping machine. To mitigate this challenge, we modified the surface course and utilised Plastipave Thin®, eliminating the need for pre-coated chippings while maintaining the necessary skid resistance. This innovative approach enhanced operational safety by reducing the required road width and minimising the number of on-site personnel.

Sustainability

Plastipave offers a long-term, cost-effective, and sustainable approach to road construction by incorporating recycled plastics and tyre crumb. This not only diverts waste from landfill but also reduces carbon emissions.

Through recycling, warm mix technology, and the use of waste materials, this project achieved a carbon saving of 14.45 tonnes. Additionally, 318.90 tonnes of planings were recycled.

To enhance skid resistance in junctions and high-risk areas, we successfully tested a locally produced high PSV aggregate. Targeting a minimum scrim level of 5.5, testing consistently yielded results above 6.0.

Summary

The project achieved improved operational safety and reduced environmental impact. This case study highlights the company’s ability to deliver innovative and sustainable road infrastructure solutions.
