Road Maintenance Decreases Greenhouse Gas Emissions


Maintaining roads in a good state in an exemplary shape conserves money and energy and minimizes the greenhouse gas emissions, more than neutralizing pollution engendered during road construction.

The researchers discovered that increasing the viability of pavement through deterrent can minimize greenhouse gases by up to 2 percent; transportation agencies can slash disbursing by 10 percent to 30 percent and drivers can conserve about 2 percent to 5 percent in fuel utilization, tire wear, vehicle overhaul and maintenance costs due to smoother surfaces.

The research will assist transportation firms select suitable conservation procedures that contemplate environmental influence in decision making. Study lead author Hao Wang, an associate professor who focuses on infrastructure engineering in the Department of Civil and Environmental Engineering said that when pavement is its premature failure stages preemptive conservation can reinstate implementation and expand pavement life with diminished costs. Pavement conservation marshals to important environmental advantages due to enhanced surface constrain which develops in smooth pavement conserves energy and diminishes user cost.

The transportation sector is the biggest origin of greenhouse gas emissions, predominantly carbon dioxide from cars, trucks and buses. The researchers utilized the long-term pavement performance (LTPP) database preserved by Federal Highway Administration of U.S. Department of Transportation to evaluate the environmental influence of roadway overhauls especially protecting asphalt pavement, in relation to carbon dioxide emissions connected to global warming.

The study utilized an entire cycle perspective to observe carbon footprint of customary ways to conserve pavement.
