Wheels, Tires


The old tires, those who switched to cars when they no longer serve, and we usually see them burned in any event, could have a new and better use. In Mexico took the first step and created the "llancreto", a mixture of waste tires and concrete. And used it to pave a street, they say, can last 20 years with minimal maintenance and safety average. The new technique promises to solve the problem of recycling of this highly polluting. The street in question is located in the municipality of San Pedro Garza Garcia, a suburb of the northern city of Monterrey.

For the preparation is used about 200 cubic meters of concrete and a disposable rubber 2800, ie 14 per cubic meter. The project was supported by the cement company Cemex. This is the first street to be paved with this technique, but the Mexican Environment Secretary Alberto Cardenas said that this method is part of a pilot scheme that could spread to other parts of the country. In addition, Cárdenas expected to "llancreto" can be used for rough use, ie for highly trafficked avenues that support heavy truck traffic. The concrete was perfected after several years of research resulting in a durable, safe and promotes sustainable development, according to Secretary Cárdenas.
