Cold mix road repair material containing 100% recycled asphalt has been laid on rural routes in north Wales, UK, by the contractor Hogan Construction (part of 3943 Hogan Group).Work was carried out to demonstrate that structural integrity can be restored to a failing carriageway without making use of primary aggregates or hot bitumen.

Over 500tonnes of recycled material featuring a Nymuls CP50 emulsion – supplied by 294 Nynas – was laid as a binder course on three sites this summer on behalf of local authorities in Gwynedd and Anglesey.

The cold mix material was laid and compacted at an ambient temperature before being overlaid with a surface dressing. Hogan’s Director of Business Development David Morris said: “We wanted to lay an asphalt made up of 100% recycled material because we saw the potential to reduce the use of primary aggregates in the highway maintenance process. The clients are perfectly happy with how the material has performed so far.”

Heavy traffic on a road stretch in northern Algeria has resulted in the need for rebuilding of the link, making it better able to cope with demand. In Algeria’s Msila region, the RN 45 road carries over 700 heavy load trucks/day, 365 days/year and required a major re-construction. In 2017, La

    The use of reclaimed asphalt pavement (RAP) is common practice in many countries. The aged bitumen from RAP has a lower penetration and is more viscous than it was when first mixed. The reclaimed bitumen is generally balanced by the addition of fresh binder softer than the traditional one used to produce hot mixes. However, balancing penetration and softening point or viscosity does not produce an identical bitumen to the original one. One fundamental option is the regeneration of the aged binder in order t
