DPWH approves use of plastic waste to extend asphalt lifespan

Published Aug 12, 2024 08:40 am

The Department of Public Works and Highways (DPWH) has allowed the use of plastic waste to extend the lifespan of asphalt pavements and mitigate plastic pollution, which contributes to flooding in urban areas.

DPWH Secretary Manuel Bonoan has issued a directive mandating all DPWH regional offices, district engineering offices, and Unified Project Management Office clusters to incorporate shredded plastic in road construction projects.

The directive, outlined in Department Order 139, series of 2024, sets a new standard for the use of recycled materials, specifically low-density polyethylene (LDPE) plastic bags, in bituminous concrete surface courses.

Bonoan said the latest policy not only promotes recycling efforts but also improves asphalt’s resistance to deformation.

“This development is in line with the continuing efforts of the Department to support sustainable engineering and upgrade construction technology through the adoption of successful research studies,” he said.

The order, which requires the use of recycled materials, has undergone rigorous testing and meets the standards established by the Bureau of Research and Standards, the DPWH said.
