As roads break down, small micro particles of plastic are released into the surrounding environment and can have detrimental impacts on wildlife and human health. But life in plastic, isn’t always fantastic. Cumbria in the UK adopted this for all new roadways. This process makes the road considerably stronger and last much longer than traditional material. You need 3-10kg of recycled plastic per tonne of paved asphalt. UK engineer Toby McCartney has even developed a way to turn recycled plastic into pellets that can be added to asphalt to decrease the use of binders. But what if we replace these finite resources with one of humanity’s infamous biproducts, such as plastic? India has been filling potholes using plastic as a binder on a small scale for years. It is made from quarried aggregates – such as limestone, granite or sand – bound with cement, bitumen (asphalt) or other agents. Volvo Construction Equipment takes a trip down the roads of the future to look at some incredible innovations and find out just how design, materials and use will adapt in the years to come Recycled plastic is added to asphalt mix Plastic RoadsĬoncrete production contributes to 8% of global CO² emissions according to the WWF. And by 2050 our global network of highways is projected to increase by 60%. As cars get smarter so too should the infrastructure that supports them.
In the past 50 years there have been huge advancements in the automobile industry but the roads we drive on remain nearly unchanged.
