Concrete is a widely used material in construction that can withstand compressive load, Because of its brittle nature it is susceptible to cracks. Theses cracks in the field of pavement construction leads to ingress of fluids or substances into the lower layer of roads. Thus the leads to failure of cracks within the life of concrete. To avoid and overcome these cracks, need of increase in strength and durability of concrete. Especially in development of flexural strength of concrete. Introduction of bacteria into the concrete mixture works by precipitation of calcium carbonate to fill up the cracks in concrete. In this research, extensive laboratory investigations have been carried out to study the effect of introducing Bacillus Subtilis Bacteria on the mechanical properties of concrete. With addition to this beams of standard specimen for fatigue test were casted and test was conducted for normal and bacterial concrete for the stress ratio 0.6, 0.7 and 0.8. Then the results were compared. The experimental results of Bacterial Induced Concrete Pavement and plain concrete are discussed for M40 Grade of concrete for two type of cement. The results shows that bacterial induced concrete for OPC mix is 18% increase in compressive strength, 13.84 % increase in flexural strength and 11.32% increase in Split tensile strength when compared with normal concrete. The fatigue behaviour is studied and compared with IRC recommendations
