The Carbon Footprint of Asphalt Pavements: A Reference Document for Decarbonization
In this follow-up to the GHG Emissions Inventory, NAPA is taking proactive steps to provide a roadmap for the industry and agencies to leverage unprecedented levels of federal funding in IIJA, IRA, and other federal programs to reduce greenhouse gas (GHG) emissions. It details specific actions individual companies and agencies can take to reduce GHG emissions – making it useful to pavement engineers, asphalt mix producers, paving contractors, policy makers, and other stakeholders with an interest in reducing embodied carbon emissions associated with asphalt pavements.

Production Strategies for Saving Money and Reducing Emissions
QIP-132 aims to help mix plant operators apply learnings from QIP-126 and QIP-127 to conserve energy and reduce costs. Details specific opportunities related to the drying/heating process, maintaining adequate storage temperatures, and electrical energy use. Includes self-audit worksheets to make it easy to evaluate individual facilities.
Benefits of Prioritizing RAP
This document underscores the economic, environmental, and performance advantages of prioritizing Reclaimed Asphalt Pavement (RAP) in asphalt mixture production. Road owners can achieve substantial cost savings, reduce environmental impact, and enhance pavement performance by embracing RAP, according to the comprehensive findings. The asphalt pavement industry is urged to prioritize RAP utilization for sustainable resource management, reduced emissions, and long-term cost efficiencies.
Agencies & Contractors Surveys on Barriers to Higher RAP Usage in Asphalt Mixtures (SR-229, June 2024)
Agencies & Contractors Surveys on Barriers to Reduce the Production Temperatures of Asphalt Mixtures (SR-230, June 2024)
In this pair of reports, we examine what agencies and contractors say are barriers to increasing usage of reclaimed asphalt pavement (RAP) and warm-mix asphalt (WMA) technologies. Based on surveys conducted in 2023
5 Benefits of Asphalt Pavement Milling
Milling is a fundamental practice in the maintenance and rehabilitation of asphalt pavements. This paper explores the multifaceted benefits of milling, highlighting its role in restoring pavement geometry, facilitating material recycling, removing deteriorated materials, aiding in surface preparation, and preserving existing infrastructure. By exploring each benefit, this paper illustrates the significance of milling as an essential component of modern pavement management strategies.
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.
Sustainability and Resilience
Sustainability and resilience are concepts that are increasingly at the forefront of the planning, design, construction, and management of transportation infrastructure in general and pavements in particular. The two terms are often used interchangeably, yet they are distinctly different concepts.
Resilience of Perpetual Pavements
Perpetual pavements are well known for sustainability benefits, but did you know that they also provide substantial benefits with respect to resilience?
Climate Adaptable Materials for Resilient Infrastructure
Climate change is increasingly becoming a primary concern in the design, construction, operation, and maintenance of transportation infrastructure. New approaches, techniques, and tools are needed to address the challenges posed by climate change to increase the resilience of our infrastructure to both gradual changes and extreme events.
With support from The Road Forward, NAPA's Plant Operations Subcommittee developed the Plant Efficiency Series to help asphalt mix producers with specific operational topics.
Driving Sustainability with Key Performance Indicators (KPIs) in the Asphalt Industry
The use of KPIs is increasingly hailed as an effective way to measure and manage environmental performance.
