RE: Less holes, graphene asphalt works And now we are thinking of extending it in the city24 Jun 2020 15:06
Graphene Asphalt experiment. Thanks Itsyou.
Published May 21, 2020 The graphene asphalt experiment carried out on a section of the Milan-Meda is one of the systems put in place to improve the conditions of the roads in the Milanese belt. It was discussed yesterday during the joint Urban Planning and Mobility Commission of Palazzo Marino. The test carried out in recent months has combined Metropolitan City and Iterchimica who worked on the refurbishment of a stretch of the high-flow artery with Ecopave, an additive to asphalt based on high-performance and environmentally friendly graphene. Result: an increase in the duration of the coat by 250%. The project was funded by a call from the Lombardy Region. "We want to make an experience available, experimenting with certified forms of innovation that bring an advantage of environmental sustainability to the benefit of the community", stressed Arianna Censi, Deputy Mayor of the Metropolitan City. But there is also more, such as the imminent realization of a "mapping of road surface anomalies". Not a simple undertaking on 711 kilometers, the network of metropolitan cities, including 150 kilometers of urban streets. Also counted the 3m high bridges, which are 518 and will be monitored with satellite images, and the roundabouts, 300.
The results of the 4-month experimentation are already available, during which sensors were positioned on the cars of two roadmen: 1,493 anomalies were detected, 4 with high gravity. A software scans the road conditions in real time as the car passes. Now, 11 devices have been mounted on as many service machines and detection will start in days. In addition, video surveillance systems will be placed at the staging areas, against the garbage of waste. Returning to the experimentation with graphene, "why not use it in Milan? - asks Fabrizio De Pasquale (Forza Italia) -. The maintenance is not satisfactory, the roads are full of holes. And then more control could be carried out remotely and through the satellite". It is not to be excluded. The technicians specified that " it must be assessed according to the individual roads and the context ", considering for example the average speed of the cars and the frequency of interventions on the underground services. The Councilor for Mobility Marco Granelli highlights that" we must work more and more on the quality of materials and innovation, to achieve greater environmental sustainability. We are building, in agreement with the Polytechnic of Milan, a cadastre of the streets and we have allocated 49 million for maintenance. Not only that: we favor companies that do not bring the scarified asphalt to landfill (demolished at the passage of the milling machine, editor's note) but that reuse it, with a view that respects the environment ". Marianna Vazzana The Councilor for Mobility Marco Granelli points out that "we must work more and more on quality of materials and innovation, to achieve greater environmental sustainability.
