Paving the way: Plas­tic road­ing

Element - - Contents -

A plas­tic-based as­phalt is be­ing tri­alled for paved roads in the Cana­dian city of Van­cou­ver. The ma­te­rial is been made from plas­tics such as used water bot­tles and yo­ghurt pots, which are ground to a mash and mixed with stan­dard as­phalt. When it is heated it flows around the ag­gre­gate and binds it to­gether. The ma­te­rial has so far proved to be as durable as tra­di­tional ma­te­ri­als.
