Research & Best Practices

GHG Emissions Inventory for Asphalt Mix Production in the United States

This first-of-its-kind report documents the asphalt pavement's contribution to GHG emissions nationwide, including avoided emissions achieved with current technologies, along with comparisons to related sectors and research needed to continue reducing emissions.


Readily Implementable Asphalt Technologies

With an ambitious goal of achieving net zero carbon emissions by 2050, you may be wondering what you can do now. There are many opportunities to optimize asphalt pavement materials, mix production practices, paving operations, and pavement design. Explore these resources to begin implementing environmentally friendly practices, optimizing your operations, and addressing your bottom line – today.


Efficient Trucking

Trucking represents a significant cost in the production and placement of asphalt mixtures and contributes to greenhouse gas emissions. In the effort to optimize trucking operations and lower emissions, asphalt producers can focus on planning, scheduling, and management/execution. Download this report to find strategies and techniques within each of these areas, along with a Tactical Checklist to complete a self-audit and find opportunities to increase efficiency.


Operational Tips: The Road Forward to Lower Emissions and Higher Profits

This expanding series of case studies explores opportunities to reduce environmental impacts while improving business practices.

Insulating to Prevent Loss of Thermal Energy, Reduce Fuel Use and Reduce Costs

Granite Construction Co. shares its data on the benefits of pipe insulation to minimize thermal energy loss — within one year the project paid for itself by reducing energy consumption by 55 percent. 


Electric Heated Tank Farm

Learn how an electric asphalt tank farm, an existing technology, was leveraged by Orlando Paving Co. to reduce carbon emissions by 99.5% and save 16.5% on energy usage.


Paving Under Stockpiles Pays Off Environmentally & Economically

This case study shows how paving under stockpiles can reduce aggregate moisture and therefore reduce fuel consumption. Read how they did it at Michigan Paving & Materials, A CRH Co.
