Minimising waste using recycled materials
Combined drainage and kerb units are used in the main on highway schemes with carriageway crossfalls and are also useful for flat, contained paved areas such as car parks. Traditionally kerb drain units have been made from polymer resin concrete compounds, however a number of manufacturers now offer alternative kerb drains made from recycled products.
Our A3 project has identified a sustainable alternative, to traditional concrete units and is utilising kerb drains made from recycled products. Components include a light-weight polymeric based recycled material called Vienite, which was developed by ACO Technologies. The ACO KerbDrains have been installed within the A3 tunnel, on the Hammer Lane bridge deck, within the underpasses and the on roundabouts at Hazel Grove. For the tunnel alone, at least 3.6 kilometres of kerb drain has been made from recycled product.
The use of recycled materials, rather than concrete, reduces the demand for primary aggregates as well as the volume of waste taken to landfill.
ACO KerbDrains can also be produced as one-piece units and are much lighter than traditional two-piece concrete units, which offers significant health, safety and programme benefits.
