Effect of Design Conditions on Life Cycle Cost and Co2 Emission of Concrete Pavement Considering Fatigue Cracking

Key Points

• The research evaluates how design conditions influence the life cycle cost and CO2 emissions of concrete pavement considering fatigue cracking.
• Assessment of economic and environmental impacts during the life cycle of concrete pavement.
• Analysis of design parameters such as slab thickness and joint spacing.
• Comparison of continuous reinforced concrete pavement with standard jointed pavement and recycled asphalt pavement.
• Increased slab thickness and reduced joint spacing improve fatigue resistance.
• Enhancements lead to reduced environmental and economic impacts on concrete pavement.
• Continuous reinforced concrete pavement requires less repair than jointed concrete pavement, resulting in lower overall load.
• Overall life cycle impacts of recycled asphalt pavement are also lower compared to standard options.
