The three Rs of the circular economy – Reduce, Reuse and Recycle – could be used as the promoting mantra for UK based OCL Regeneration as they pave the way for more sustainable road resurfacing practices.
Over ten years in the making, the Welsh Government’s new surface course specification centres around stone mastic asphalt (SMA) and hopes to significantly increase the service life of the road surface materials.
Using cold recycling technology developed in-house, Aggregate Industries has taken a major step in the direction of more sustainable pavements.
In a recently published white paper, Nynas outlines benefits and carbon footprint calculations for an upcoming range of binders incorporating biogenic material. The new product range will contribute to lowering the carbon footprint of a road.
Nynas is investing SEK 190 million to secure the supply of bitumen for the Nordic infrastructure. At the same time, carbon dioxide emissions can be reduced by 34%.
Eurobitume is carrying out longterm work to help the organisation’s members to prepare for upcoming challenges as the conditions change in the market. One example is the decision to form the Bitumen Sustainability Steering Group (BSSG), chaired by Carl Robertus from Nynas.
The reuse of asphalt is one area where the bitumen and asphalt industries contribute to a more sustainable utilisation of our natural resources.
All of Nynas bitumen product transport operations in Sweden using road tankers now run virtually exclusively on biofuel.
All municipalities have at least one section of road that constantly requires maintenance, surfaces that can never be satisfactorily repaired and are always on the waiting list for new measures. One such example is the junction of Pilsworth Road and Moss Hall Road in the English town of Rochdale.
The choice of paving materials affects not only the useful life of a road, but also the environment. The temperature of the asphalt mix also plays a role in this context.
