Maine buried 20,000 old tires beneath a road and they helped against frost damage. Now engineers are exploring them for walls, highways and more

In an innovative engineering experiment, shredded tires were utilized in road construction, effectively tackling both durability and tire waste problems. The incorporation of tire chips offered enhanced insulation and superior drainage underneath the road surface. This groundbreaking method outperformed traditional gravel, particularly noted during the spring thaw, revealing discarded tires as a valuable resource in construction.
