Temperature–water–load coupling study on stress characteristics of BFRP–CRCP pavement

The stress characteristics of continuously reinforced concrete pavements with basalt fibre-reinforced bars (BFRP–CRCP) were investigated using the temperature–water–load coupling theory, based on the characteristics of frozen soil in Northeast China, combined with existing research experience, and taking the foundation thaw settlement effect in Northeast China as a starting point. The COMSOL finite element software was used to create a finite element model of the BFRP–CRCP subgrade and pavement China. Several common affecting elements, such as pavement thickness, reinforcement ratio, and concrete modulus, were examined, and appropriate recommendations for BFRP–CRCP pavement material selection were made. Further, the stress characteristics of the BFRP–CRCP pavement structure combination were investigated utilising three common structural forms of pavement in the region and focusing on distinct contributing elements. It serves as a model for BFRP–CRCP pavement construction that considers settlement deformation.
