Jointed plain concrete pavement (JPCP) is the widely preferred conventional concrete pavement for highways; however, the higher initial construction cost and extended time for traffic opening limit its applicability. Recent advancements like roller-compacted concrete pavement (RCCP) could address the above concerns of JPCP. Yet, there is a lack of knowledge and comparative studies on the performance assessment, sustainability, and economic analysis of RCCP and JPCP. Therefore, this study aims to evaluate the engineering properties (density, compressive and flexural strength, and fluid flow properties), cost analysis (materials and initial construction cost), and sustainability (carbon dioxide emissions and energy consumption) of both pavements. The fresh density and mechanical properties of RCCP were 8%–9% and 13%–35% higher than JPCP; thus, 44%–89% and 24%–57% reductions in water absorption and porosity were observed in the considered RCCP mixes against JPCP. The higher strength properties of RCCP significantly reduced the pavement thickness by 10%–25%, thereby lowering the materials and initial construction costs by 52%–78%. Further, sustainability assessment through the cradle-to-gate (from raw material extraction to transportation phase) and gate-to-gate (only concrete production in a ready-mix plant) approaches revealed that employment of RCCP could significantly reduce carbon dioxide emissions (9%–30%) and energy consumption (10%–32%) compared with JPCP mixes. The findings show that RCCP can be considered sustainable, economical, and higher-performance pavement than JPCP.
