In 2026, Texas engineers mixed 4.5 tons of waste plastic into nearly a mile of road; the recycled material replaced 8% to 10% of petroleum-based bitumen

Innovative researchers are pioneering the use of recycled plastic to improve the durability of asphalt roads. By substituting a portion of traditional bitumen with plastic materials, they have observed encouraging results in early field tests, indicating enhanced resistance to heat and cracking. Additionally, laboratory studies demonstrate increased pavement stiffness and strength. This groundbreaking approach not only strengthens roads but also provides a sustainable solution for managing plastic waste.
