Evaluating the economic and environmental impacts of road pavement using an integrated local sensitivity model

Assessing the life cycle economic and environmental impacts of road pavements is critical for achieving long-term sustainability in transport systems. Life cost analysis (LCCA) assessment (LCA) methods have been widely applied to pavements, however, there still a need identify which approaches boost both benefits, simultaneously. This study develops an integrated LCCA-LCA method, identifies merges common inputs from LCCA LCA models. A local sensitivity conducted most influential model, more effective measures reduce costs pavements. The results show that only 10 inputs, 568 studied, affect significantly. Important leading reduced pollution with less include: traffic volume, surface area, heavy-duty vehicle ratio, speed, other design parameters (standard normal deviates, combined standard error, asphalt layer thickness, base structural coefficients, drainage coefficients).
