The present article aimed to evaluate the bearing strength of basalt fibre reinforced recycle aggregate concrete with bearing area ratio of 10 and 15. Total ten mixes are taken for experimental work, among them 5 mixes with basalt fibres and 5 other mixes without basalt fibres. The natural aggregate was replaced by the recycle aggregate in the volume proportion of 0,25,50,75 and 100% and the basalt fibres are added to the mixes in the proportion of 4kg/m3.In addition to bearing strength, for all mixes compressive and split strengths are evaluated. For obtained bearing strength results, regression models are developed to estimate the bearing strength as function of cube compressive strength and % of basalt fibres. The results showed that, the bearing strength for 50% recycle aggregate concrete mix exhibited more strength when compared with all the mixes (without fibres) and with addition of fibres the strengths are increased for all the mixes.
