NHAI trials reclaimed bitumen on stretch of Chennai-Tirupathi National Highway
India’s National Highways Authority is testing reclaimed bitumen—a recycled asphalt material—on a section of the Chennai‑Tirupathi National Highway. The pilot involves laying the reclaimed mix over a defined stretch, with engineers monitoring its strength, durability and cost‑effectiveness. Officials say the trial aims to evaluate whether the recycled product can meet standards and reduce construction expenses before wider rollout.
