The transportation of materials (largely asphalt) continues to contribute greatly to the overall emissions generated in our operations. Methods to reduce the need for renewal of road surfacing and foundation includes ‘retexturing’ and ‘crack and seat’ techniques. These techniques are regularly employed to increase the longevity of the road structure without reconstruction or replacement of in-situ materials as far as practicable. Asphalt Recycling The majority of asphalt waste is recovered for reuse or recycling through our supply chain. This isn’t currently possible when waste is contaminated with coal tar. To improve the recovery of coal tar contaminated planings we are preparing to undertake a trial that will enable its use at the same site following processing. This puts previously contaminated material to purposeful use within the structure of renewed road surfacing. Significant benefits are afforded both by reducing material imported and waste disposed off-site.
