Cold mixing on the go

A successful collaboration between Nynas and volumetric concrete mixer manufacturer Armcon has resulted in a mobile patching machine that can produce cold mix asphalt for repairs and maintenance.

After two years of development, Armcon has produced a version of its market leading mixing equipment that is designed specifically for producing cold mix materials made using road plainings and bitumen emulsion from Nynas.

Barnsley Metropolitan Borough Council in South Yorkshire is the first local authority in the UK to use the equipment. Key advantages include the fact that Barnsley MBC are in control of production to meet demand, the material is easier to install and work with on site and can also be stored for extended periods.

This gives the local authority a lot more flexibility compared with using hot mixes enabling them to manage programmes, which in turn generates cost savings to the business. The Armcon machine can produce cold mix materials on a continuous basis, which can then be stockpiled and used by different gangs as and when they need it. As a result, the Barnsley maintenance team is entirely self-sufficient and doesn’t have to rely on deliveries from external suppliers.

Barnsley MBC is currently using the cold mix for footway repairs and plans to use it for carriageway repairs in the future.

Projects

Hessen, Germany

During 2020, slip roads to and from motorways all over the federal state of Hessen in Germany have been paved using microsurfacing to improve road grip. Because of the heavy traffic, especially in the Rhine-Main area, the contractors were forced to perform the work largely at night, which posed major challenges for both employees and machines, but also for construction materials.

Projects

The road network, Sweden

More and more car drivers are complaining about the standard of the roads and demanding better maintenance, primarily on the less trafficked road network. And statistics support them. Costs for car repairs associated with poor road conditions are increasing rapidly.

Safety

Minimising the risk of boil-over

It is extremely important that the driver always makes sure that the tank is free of water or aqueous products before loading bitumen.

Sustainable Development

Nynas invests for reliable production and reduced GHG emissions

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%.
