Research Reports

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.


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.

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.


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.
