When natural disasters strike, state and local agencies need resilient pavements that offer both a quick fix and a long-term solution. Resilience is the ability to anticipate, prepare for, and adapt to changing conditions. Withstanding, responding to, and recovering rapidly from disruptions are critical to reopening affected communities. In the wake of natural disasters, emergency vehicles need to deliver services, construction equipment must arrive to make repairs, and other vehicles need to haul off debris. Roads are essential lifelines for construction crews, local businesses, and residents who are eager to return home quickly and resume their normal activities.
Fixing a disaster-ravaged road is a challenge that requires anticipation, preparation, and a rapid response. Louisiana inadvertently discovered a process that saved its roads from needing repairs after flooding events from major storms. In the late 1990s, two parishes worked with Prairie Contractors LLC to develop a low-cost solution to reduce serious and fatal accidents on rural roads.
The Earth is a precious resource, and as stewards of our planet, the asphalt pavement industry recognizes its responsibility to take care of the planet for future generations. With a long track record of working alongside agencies, regulators, and academia, the asphalt pavement industry is committed to reducing its greenhouse gas emissions by detailing historical efforts, setting realistic industry-wide reduction goals, and implanting a roadmap to reduce our environmental impacts.
The United States has established long-term temperature reduction goals by signing the Paris Agreement. The asphalt pavement industry is committed to supporting the government’s articulated goals and detailing the two existing technologies, warm-mix asphalt (WMA) and reclaimed asphalt pavements (RAP), which reduce energy consumption and minimize greenhouse gas (GHG) emissions.
Use of Warm-Mix Asphalt and Reclaimed Asphalt Pavement to Reduce Energy and Greenhouse Gas Emissions
As the industry continues to look for new ways to reduce its impact on climate, furthering the use of two proven technologies like RAP and WMA should be prioritized. The impacts of both are well documented, and research has proven that the production and construction of high-quality, sustainable asphalt pavements provide benefits to the environment, communities, and businesses.
