Pavement Rehabilitation Policy for Reduced Life-Cycle Cost and Environmental Impact Based on Multiple Pavement Performance Measures

Pavement structures are fundamental elements of the automobile transportation system. Deterioration of pavement condition will increase both vehicle operating costs (e.g., fuel consumption, vehicle wear and tear) and greenhouse gas emissions. Pavement condition may be maintained at an acceptable level through rehabilitation activities over the service life span of a pavement. Traditional pavement rehabilitation policy is primarily based on minimization of the life-cycle cost incurred by both agencies and users. The environmental impacts associated with the cost-effective rehabilitation policy are typically ignored. This proposed project intends to develop a methodology for selecting pavement rehabilitation policy by considering both cost factor and environmental impact (energy consumption and pollutant emission). The project will be conducted in phases. Phase I work is close to completion, which is to develop a life-cycle assessment (LCA) framework for pavement maintenance and rehabilitation (M&R). In Year 2, Phase II research will focus on developing pavement performance models with consideration of both environmental factors (temperature, rainfall) and rehabilitation activities (e.g., milling and overlay). To be specific, to account for correlation effects among pavement roughness, cracking, and rutting, multiple pavement performance indicators (International Roughness Index [IRI], rut depth [RD], crack rating [CR]) would be evaluated simultaneously by means of system-equation approaches. Long-term pavement performance (LTPP) data will be collected and used to develop a multivariate pavement performance model. Then, a case study will be conducted to select pavement rehabilitation policy for single facility with dynamic programming (DP) algorithm.
