Optimized Strategies for Reducing Greenhouse Gas Emissions during Flexible Pavement Life Cycle
Publication: International Conference on Transportation and Development 2024
ABSTRACT
The United States government has committed to improve the nation’s preparedness and resilience to the effects of climate change by targeting net-zero greenhouse gas (GHG) emissions by 2050 and limiting global warming to 1.5°C. The Department of Defense (DOD) is supporting this initiative by developing strategic processes to ensure net-zero emissions from federal procurement. DOD’s climate adaption plan outlines five lines of efforts (LOEs); LOEs 1 and 4 are of particular interest to the pavement’s community. LOE 1 includes consideration of the social cost of GHG emissions; LOE 4 deploys GHG emissions reduction technologies. This paper explores GHG emissions reduction strategies for DOD and includes estimates of baseline GHG emissions from documented sources associated with construction and maintenance and rehabilitation of flexible pavements. Documented GHG emissions data are used to establish expected emissions reductions for each strategy. Optimized GHG reduction strategies are highlighted using an airfield pavement case study.
