Abstract

Designing rigid pavements involves two major critical decision-making processes to balance performance with cost-effectiveness and sustainability. This paper discusses an integrated approach of MCDA and LCCA for the optimal design of rigid pavements. While MCDA considers a wide array of criteria, including structural integrity, material selection, environmental impact, and user comfort, among other concerns, LCCA reflects the long-term economic implications comprising construction costs, maintenance costs, and end-of-life costs.


The key decision-making parameters have been identified, and weights are assigned to them with the contribution of the stakeholders in order to make it practically relevant. The application of the proposed framework in case studies has demonstrated that the developed study framework can easily rank different design alternatives and select the most economically viable solution with a minimum sacrifice of sustainability and performance.


The results indicate that integrating MCDA with LCCA offers transparency for stakeholder involvement in rigid pavement design. This economic approach is oriented toward resource optimization and long-term infrastructure sustainability. With the capability to be adapted to project conditions ranging in their parameters, the proposed methodology can become a strong tool for policymakers, engineers, and planners. This paper tends to move toward sustainable and economically viable pavement solutions for the complexities of decision-making in infrastructure projects.
