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.

For more information see:

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