In 2001, Indiana used shredded scrap tires beneath State Road 31; after a year of monitoring, the unusual road fill showed low settlement and minimal internal heating

In Lakeville, Indiana, a fascinating project incorporated shredded car tires into highway embankments, proving beneficial for waste management while ensuring road integrity. Over the course of a year-long study, officials noted negligible subsidence and no major heating issues. However, prevailing regulations and contractor biases remain significant barriers to the broad application of this innovative recycling technique in construction, highlighting the ongoing struggle to adopt eco-friendly practices within infrastructure.
