In California, in-situ cold recycling with a Wirtgen 3800 CR recycler has proved to be the most economical solution. In the US’s Golden State – California – Wirtgen’s 708kW powerhouse the 3800 CR recycler resurfaced 160km of San José’s main traffic arteries in situ, on-the-spot. The 3800 CR worked with a Vögele VISION 5200-2i tracked paver in a rear-load process. With this method, the 3800 CR travels in reverse, removing the damaged asphalt layers in a down-cut process and transferring the recycled material

Debate continues to swirl around the use increased recycled asphalt for road surfaces. David Smith, development director at FM Conway urges more cross-sector work to prove the case for a higher recycled asphalt content. The use of recycled materials within our road network is well-established, but a persistent debate continues around the extent to which asphalt can be reused. Although increasing the proportion of recycled asphalt offers significant economic and environmental benefits, there remains a resist

The race track used for the Malaysian Grand Prix has benefited from a repaving of its surface. This has helped boost the quality of the surface, making it smoother as well as providing more grip and also allowing it to drain more effectively during periods of heavy rainfall. A key component of the work has been the use of the Shell Cariphalte Racetrack material. This is a special high performance version of bitumen specifically developed for use on racing circuits. The 5.543 km track was resurfaced prior
