Three asphalt EPDs published in the US
Three EPDs have been published (by one Californian company) for hot mix asphalt with 0%, 15% and 25% RAP respectively. What is special about these EPDs is that they are published under an industry administered program: Emerald Eco-Label.
The National Asphalt Pavement Association (NAPA) has developed an easy-to-use tool to help companies report the potential environmental impacts of an asphalt mixture.
The web-based tool makes it easy for a company to input data about all cradle-to-gate activities involved in creating an asphalt mixture, such as fuel and water used at the plant and during transportation; aggregate, binder, additives; warm mix technologies; and recycled materials.
To ensure data entered is confidential, the tool is hosted by a third party. NAPA doesn’t have access to a company’ sensitive information. The tool generates EPD reports stating the potential environmental impacts of the mix.
The Emerald Eco-Label program was developed in conformance with ISO 14025:2006 and EN 15804:2012, and thus has the same foundation as the Australasian EPD Programme. The EPDs look a bit different (more compact) from those in the Australasian EPD Programme, but contain the key elements you'd expect.

The recently published Australian regional appendix to the PCR for asphalt mixtures applies some of the elements from the NAPA program.
