Product Category Rules
Information used in an EPD is based on an LCA methodology following certain product-specific requirements and boundaries, referred to as Product Category Rules (PCRs). These are the rules a product must follow to develop and publish and EPD in order to create a fair, credible report.
NAPA and a group of industry experts developed a North American PCR for asphalt mixtures. Members of the public submitted comments on the PCR during the public review period.
The NAPA asphalt-mix PCR will be updated every five years. This page will be updated in the future with updates and information on future PCR revisions.
