Automated road repairs using 3D printing could save money and reduce disruption, reports Kristina Smith
It’s the middle of the night and in the street below a team is busy carrying out repairs to the road surface. But there isn’t a human in sight.
A road-repair drone has landed at the site of a crack and a 3D asphalt printer is now busy filling in that crack. A group of traffic cone drones have positioned themselves around the repair location to protect the repair drone and divert traffic around it.
Established by former quarry planner Edward Hamilton and his wife, Genia, Hamilton Aggregates in the US state of Arkansas has grown from a single 0.202 hectare quarry to a three quarry operation in just seven years. The firm’s Bonds quarry in Clinton had an initial plant consisting of an Extec (now Sandvik) C12+ mobile jaw crusher and an E7 mobile scalper, which were rented from Brian Costello from Crushing Tigers; the local distributor of Sandvik mobile crushers and screeners. Showing sound business sense,
With the rapid development of autonomous and electrified vehicles, Swedish heavy truck and bus manufacturer Scania is developing a new test track in Södertälje, 40 kilometers southwest of Stockholm. To design the track to simulate multiple scenarios, Scania hired AFRY for their design and engineering expertise. The test track includes 19 kilometers of roads with more than 60 intersections and junctions, though complex, hilly ground conditions that will make layout difficult. Since changing any single element would impact numerous others, AFRY needed a flexible, accessible design environment.
Marini is offering a versatile new asphalt plant targeted at emerging markets – Mike Woof writes
A new asphalt plant from Marini has been developed specifically for the needs of customers in developing countries. The company says that this is a high-quality asphalt plant but without the sophisticated technology required in developed markets such as Europe. The versatile BE Tower is designed to be easy to transport, install and then take apart and move to a different site when needed. The company has also
