In Maine, engineers turn about 1 million scrap tires a year into lightweight highway fill; the shredded rubber stabilizes embankments built on weak marine clay

Innovatively transforming shredded tyres into construction materials for highway embankments, Maine tackled substantial waste tyre pileup while offering an affordable alternative. The tyre-derived aggregate not only lightweighted construction fill but also alleviated pressure on fragile marine clay foundations. The Portland Jetport Interchange project showcased impressive cost reductions compared to conventional methods, underlining successful tyre recycling for both civil engineering and waste management solutions.
