The Foam Stabilized Base and Emulsion Asphalt Mixture Pavement Project (herein “project”) supports pavement designers across the United States in replacing hot mix asphalt (HMA) with foam stabilized base (FSB) and/or emulsion asphalt in pavement projects. Prior to implementing project methods, pavement designers often default to using energy-intensive mining, hauling, and high temperature material manufacturing practices associated with HMA. These industry standard activities unnecessarily destroy habitats, release carbon dioxide (CO2), and release volatile organic compounds (VOC). This project reduces greenhouse gas (GHG) emitting activities throughout the pavement application lifecycle. The project reduces dependence on the mining of virgin aggregate, reduces transportation of raw materials to mix plants, eliminates high-temperature asphalt manufacturing and, in the case of in-place pavement recycling, eliminates mix-plant to job-site transportation. The project replaces virgin aggregate with reclaimed asphalt pavement. The project is conducted under VCS methodology VM0039, “Methodology for Use of Foam Stabilized Base and Emulsion Asphalt Mixtures in Pavement Application” and uses Pave Next, a web-based computer-aided-design (CAD) application, to help pavement designers compare carbon emissions between traditional and sustainable designs with similar structural properties. The project could reduce CO2 emissions by roughly 87 lb CO2 per ton of HMA replaced by FSB (or 39.46 kg CO2 per ton of material; Liu et al 2017). For example, if a project uses 180,000 metric tonnes of FSB in place of HMA it reduces emissions for a CO2e savings of roughly 7,000 metric tonnes, or 7,000 Verified Carbon Unit (VCU) credits generated. Project instances will be added under a single Project Description as allowed by Verra. Other similar Project Descriptions may also be developed with other project proponents.
Under Validation - A VVB is validating the project; the public comment period is now closed.

In implementing carbon-reducing measures, Global Emissionairy avoids negatively impacting natural environments, local communities, and the health and safety of project stakeholders, project proponents, and project workers. We invite all project stakeholders, community members, and workers to contact Global Emissionairy with any project feedback that they may have.
