Green drive- plastic to be used for laying roads

Posted by keerthi sureshbabu on August 6, 2011 at 4:55am
According to this, the molten plastic would be mixed with heated blue metal pieces and then mixed with bitumen. The molten plastic would form a thin layer over the metal binding the road strongly. This reduces the use of bitumen.
Global anti-incinerator alliance says, when roads degrade, the plastic which is non biodegradable will permeate the soil and pollute the ground water.
But this method is not been adopted anywhere. Will this be a good idea of disposing plastics?
Molten plastics and metal pieces melting will not degrade, because of this will the road be in good condition for a long time. These days with improper mixing, the road laying is in such a situation that after rainy season there are plenty of pot whole on roads. In such a condition will plastic on roads be green drive/ride?

    Dreading the toxic fumes, and how the laborers would be affected by this practice.

    Plastics and plasticizers are not easily degraded and would finally reach air as SPM of road origin and as soluble and suspended matter in road run off which will finally reach receiving water bodies. Miscibility of plastics with tar is not properly evaluated by proponents of tarcrete application. Safety of road surfaces for high speed vehicle run is also not available. Some half baked research has reported use of assorted plastics in tarcreting. A serious scientific evaluation is needed.

    Pot holes cannot be stopped by mixing plastics, meanwhile they can be disposed in this process. The temperature of the process needs to be controlled to check the dioxin formation. Plastic to oil is another patented process.

    Good proposal
