Tyres-Tarmac Mix;First UK road to use the scrap tyres mix a great step forward
Breedon Aggregates have successfully completed the relaying of the A90 road in Scotland. The most remarkable thing about this is that they used a mix of tarmac and shredded waste
tyres. The trial of the new tyres based tarmac was ordered from Transport Scotland and the new road with the new Tyres-Tarmac Mix, will be monitored and tested by them over a period of time.
As we all know in the tyre industry,that this is a massive step forward and the new Tyres-Tarmac Mix has a very promising future. The A90 road runs between Perth and Dundee and is a duel-carriageway for most of its length. This particular stretch of road is one of the busiest in the country and is expected to be a great test for the Tyres-Tarmac Mix. The road carries about 35,000 vehicles a day and is exposed to very inclement weather conditions.
The new material will be rigorously tested over the next few years and one of the most important tests is a skid resistance test, but the signs so far are very promising and the surface has so far passed all the test.
New technology for the success of the new mix came from a Danish company,Genan. This enables the rubber particles from the shredded tyres to bind with a binding agent at low temperatures, which also helps the environment because very little heat is required.
Most people know that since 2006, European Rules have banned the disposal of waste tyres to the landfill sites, leaving very large amounts of scrap tyres to find other uses in many various forms of recycling. According to the European Tyre and Rubber Manufacturers Association, nearly 500,000 tons of scrap tyres arose in the UK in 2009. Studies show that for every ton of scrap tyres used for rubber modification of bitumen and asphalt, 1.1 tons of CO2 emissions are saved compared with burning of the tyres for use in Cement kiln heating.
One day they may buy our old tyres again?
This is a great step forward and we must thank Breedon Aggregates for their work in this field to turn a waste product such as old tyres into a wonderful new product that will benefit us all in the long run. Breedon are now going to market the new product and sell it under the brand name of Breedon Polymer R+, and the tarmac will be produced at all its English and Scottish plants, a great step forward and who knows that some day companies may once again buy the old tyres from us again ?.
