Ground potholes will not only affect traffic, damage vehicles, but also cause safety problems, and must invest resources to repair. In order to solve these problems, the Dutch researchers have developed a road to self-repair, and even promised to solve the "mileage anxiety" of electric vehicles.
Erik Schlangen from Delft University in the Netherlands stated that they plan to test this kind of self-healing bitumen. Its internal conductive steel fibers and bacteria can not only repair cracks, but can even drive electric cars on the road. Transmission of electricity. When your car is parked at an intersection, the road can be recharged and the cruising range can be extended.
There are many challenges that need to be overcome to achieve this project. An induction motor is needed to generate enough heat to force the asphalt and fiber to start the repair process. Of course, you also need to send electricity through metal and you want to receive power from the road. The car itself also needs wireless charging. Schlangen estimates that even if additional equipment is discounted, the cost of such a road is approximately 25% higher than that of ordinary roads.
However, because this model can bring benefits to urban infrastructure and drivers, the initial investment is indeed worth the money. The later asphalt corrosion needs to be supplemented with costly, time-consuming and laborious maintenance, and some cities have even been reluctant to start the corresponding road construction. If you observe it, you will find that many roads are not properly maintained.
Schlangen believes that this new model can double road life, while significantly reducing maintenance costs, thus improving the quality of the road. If there are enough red lights for electric vehicles at intersections, the demand for dedicated charging posts can also be reduced.
It is not yet clear when the test will begin, but the Netherlands began its self-repairing experiment as early as 2010. The biggest challenge may be to persuade stakeholders to participate. The government may not be willing to renovate roads, and car manufacturers may also be skeptical about installing new charging equipment. Therefore, to really realize this vision, it may take several years to wait.

Stone Plastic Composite vinyl flooring is more and more popular new style eco-friendly vinyl flooring. SPC rigid flooring is set apart from other types of vinyl flooring by its uniquely resilient core layer. This core is made from a combination of natural limestone powder, polyvinyl chloride and some stabilizers.
SPC vinyl is a luxury vinyl flooring option with a structurally rigid, 100% waterproof core. SPC is also known as rigid core vinyl, and we use these terms interchangeably. Rigid core engineered vinyl flooring is designed to look like wood or stone, but requires less upkeep.
This flooring is durable, waterproof, and perfect for DIY installation. It`s ideal for both home and commercial areas.
