Researchers from Drexel University Philadelphia, Pennsylvania, Purdue University West Lafayette, Indiana, and Oregon State University Corvallis, Oregon, USA, have made a discovery that could create roads that melt off ice and snow during winter storms. Their secret? — Adding a little paraffin wax to the road’s concrete mix. To test its snow and ice-melting ability, the team created a set of concrete slabs:
- Slab One: with paraffin-filled pipes inside
- Slab Two: containing porous lightweight aggregate that had been infused with paraffin
- Slab Three: reference slab without paraffin
Each was sealed in an insulated container and then covered with about five inches of lab-made “snow”. Both of the paraffin-treated slabs were able to completely melt the snow within the first 25 hours of testing, while the snow on the reference sample remained frozen.
