- Funded by EPSRC (EP/N010523/1), as part of the Self-Repairing Cities network, this reports a novel route to the generation of asphalt surfaces. For the first time, asphalt was successfully 3D printed by developing and optimising a fused deposition methodology to overcome difficulties with temperature control and flow rate. The printed asphalt was shown to possess enhanced ductility and toughness. Our tuneable and flexible asphalt printing system offers a targeted and precise solution for addressing potholes economically, leading to significant cost benefits to highway surfacing maintenance. The work has attracted considerable interest from highway agencies and media coverage ( https://www.newcivilengineer.com/archive/future-of-highways-maintenance-3d-printing-11-03-2019/).
