Environmental Benefits
Pavement preservation plays a crucial role in promoting sustainability and resilience in the face of climate change. By maintaining and extending the life of existing roadways, we reduce the use of virgin materials, conserve energy, and minimize greenhouse gas emissions. This proactive approach not only supports environmental sustainability but also enhances the resilience of infrastructure, making it better equipped to withstand extreme weather events. Adapting our infrastructure to these challenges ensures that our transportation networks remain reliable and safe, even as climate conditions continue to evolve. Changing sustainability standards and resiliency measures are challenging cities, counties, and D.O.T.'s to revamp and enhance their road maintenance goals.
1
Reuse of Materials
Single Machine Repaving uses 50% less aggregate and 50% less asphalt cement than conventional equivalent methods. Since 1965, Cutler’s single machine HIR process has reused more than 12 million tons of asphalt that might have otherwise gone into landfills.
​
Reduced trucking and milling, and recycling of nonrenewable materials saves energy and money.
2
Reduction of Energy Consumption
The Single Machine Repaving method provides a smaller energy consumption and emissions profile, cumulatively, than nearly every other surface reconstruction method.
​
A landmark study conducted by the Federal Highway Administration demonstrated that HIR consumes 35% less energy than conventional paving methods, saving money and conserving resources.
3
Reduction of Carbon Footprint
Single Machine Repaving emits fewer greenhouse gases than conventional methods. Energy consumption and emissions also figure into the LEED-ND evaluation of the HIR process.
