World Highways May 2021 issue features an article on graphene-enhanced asphalt pavements and the trials’ results.
The detailed article, entitled “Building green with nanotechnology”, fully describes how asphalt pavements constructed with Gipave® can be more sustainable and help reduce the environmental impact. In fact, the graphene-enhanced supermodifier Gipave® allows to build road pavements that can be two or three times more durable than those paved with conventional asphalt, thus reducing potholes formation and consequently the need for maintenance interventions. Moreover, the extended service life will lead to benefits in terms of emissions reduction and saving of resources. Gipave® contains also a specific type of selected waste plastics that would usually end up in waste-to-energy plants. The use of Gipave®, instead, allows the recycling of these specially selected plastics. It has been calculated that, for a 15 m-wide, 250 cm-thick and 1 km-long road, it is possible to recycle 18 tonnes of technically-selected waste plastics, avoiding their incineration (saving 1400 kg of CO2eq). In addition, the asphalt pavements built with Gipave® can be 100% recyclable in future production cycles.
