This study aims to evaluate the cracking risk of continuous reinforced concrete pavement (CRCP) under various mix conditions including supplementary cementitious materials (SCMs) and expansive additives (EA). A multiscale chemo-hygral computational analysis was utilized and the model was validated using strain data from lab-scale concrete and full-scale CRCP specimens. The analysis model accurately reproduced the strain behaviors in CRCP with SCMs and EA, and the analysis results showed that the amount of EA significantly reduces the risk of cracking.
