potholes! classic symbols the political failure that force drivers to navigate real minefields with their vehicles, and waiting for months (o por qué no años) a definitive solution. Some projects tried to inject technology into the streets (básicamente energía solar) and they finished a spectacular failure in or costs soared . Now, the scientist Erik Schlangen University of Delft in the Netherlands has a different idea: design roads that be repaired alone. the initial cost would be higher, but if that reduces subsequent maintenance…
four lines of public transport in both directions, heavy goods vehicles around the clock, and a shopping center less than a hundred metres… imagine the State of the streets near my home. This situation is repeated in many places of the world, and the same can be said of the general pattern: politicians love to build new streets (más aún cuando se encuentran en campaña) however, are as Carmen Sandiego time to order and pay for its maintenance. Our relationship with the asphalt is complicated. Its properties are excellent, but you need much help. The best work may last five or ten years (dependiendo deel tráfico, el clima, y otras condiciones) and that is obviously not enough. The key is prevention, fix the small problems until they become craters. Then, what such sound a way capable of regenerating these failure on their own ?
thus reach from Delft University in the Netherlands, where scientist and expert in materials Erik Schlangen works in an advanced version of asphalt with fibers integrated metal making it conductive. Applying heat using an induction system, asphalt becomes softer and fissures present close by themselves . The concept of regenerative asphalt was already assessed in a dozen ways, and one of them is open to the public from the year 2010, no signs of deterioration. Schlangen explains that still needed more time to verify the results.
the potential of this asphalt is huge, but we can not escape to the big question: do much? If we consider the special blend and the induction system, the cost can become a 25 per cent plus high compared with traditional asphalt, however, the balance becomes favorable long-term, with annual savings of EUR 90 million if all the paths of the Netherlands were made this way. If that seems little, regenerative streets have one trick in the Pocket, and the possibility of future recharge electric cars . Schlangen suggested that the first tests will be close to the traffic lights.
