Abstract
This study investigates the dual benefits of Phase Change Material (PCM) incorporation in concrete for pavement construction, focusing on both performance enhancement and energy efficiency. Through extensive mechanical testing and thermal analysis, the effects of PCM content on concrete strength and temperature stress mitigation were evaluated. Results indicate that while PCM addition led to reductions in compressive and flexural strengths, mixes containing 8% PCM maintained feasible strengths for pavement applications. Furthermore, thermal analysis demonstrated significant reductions in temperature and curling stresses with increasing PCM content, highlighting the potential for enhanced pavement durability and energy efficiency. Multi-criteria decision-making (MCDM) analysis identified the 8% PCM mix as the optimal choice due to its balanced performance across critical parameters. This research underscores the efficacy of PCM-enhanced concrete in improving pavement performance and energy efficiency, emphasizing the importance of careful PCM content selection in achieving sustainable pavement solutions.
