Bill Summary · AB 978

Legislative bill overview

AB 978 requires the California Department of Transportation (Caltrans) and local agencies to increase their use of recycled materials in street and highway construction and maintenance projects. The bill establishes standards and guidelines for incorporating recycled asphalt, concrete, and other reclaimed materials into road infrastructure improvements.

Why is this important

This legislation addresses waste reduction and environmental sustainability by diverting construction debris from landfills while potentially reducing costs for road maintenance. It also supports California's climate and circular economy goals by promoting material reuse in a high-volume infrastructure sector.

Potential points of contention

  • Performance and durability concerns: Questions about whether recycled materials meet the same structural standards and longevity as virgin materials, potentially affecting road safety or requiring more frequent repairs
  • Implementation costs and timeline: Transitioning supply chains and construction practices to accommodate recycled materials may increase short-term expenses and create logistical challenges for agencies
  • Material availability and consistency: Recycled material supply may be limited or variable in quality across regions, making consistent statewide implementation difficult
