Hybrid fiber reinforced roller compacted concrete has been widely used at home and abroad, the ratio of fiber content is one of the main factors affecting its tensile and compression properties. To study the effect of the mix proportion of basalt fiber and coarse polypropylene fiber on the tensile and compression properties of roller compacted concrete, basalt fiber and coarse polypropylene fiber were single doped or hybrid with different proportions into roller compacted concrete. The compressive and splitting tensile tests of fiber reinforced concrete at different curing ages were carried out, the hybrid reinforcing effect of basalt fiber and coarse polypropylene fiber were analyzed. The curing ages were modified based on the maturity theory, and the splitting tensile strength prediction model of basalt-coarse polypropylene fiber roller compacted concrete was optimized. The incorporation of basalt fiber and coarse polypropylene fiber not only improves the compressive and tensile properties of roller compacted concrete, but also optimizes the brittle failure characteristics and improves the toughness of concrete specimens due to the bridging effect of fibers, especially when the mass mixing proportion of basalt fiber and coarse polypropylene fiber is 1∶2, which shows the optimal positive fiber hybridization effect. The compressive strength calculated by the equivalent curing age-compressive strength equation has a better power function relationship with the splitting tensile strength, and the model is convenient to calculate and predict the compressive and tensile properties of basalt-coarse polypropylene fiber reinforced roller compacted concrete at different curing temperatures.
