India has a road system of more than 4.87kilometers according to MORTH, TechierResearch July 2015 and the
second biggest road system on the planet. Development of Road and Highways are the foundation of infrastructure
improvement upgrading the vital main thrust to accomplish quick and supported economic growth in the changing
technological innovation. It is undoubtedly the lifeline of the nation which is a never ending process activity in India.
Because of rising oil costs and a more tightly monetary environment, cement is turning into a more alluring choice for base
venture comprehensively contrasted with conventional bituminous asphalts. The Ministry of Road Transport and Highways
in India noticed that advanced society can't work adequately without concrete roads. Cement has a few deficiencies as low
tensile strength, limited fatigue life and is characterized by brittle failure resulting in nearly complete loss of loading
capacity, once failure is initiated. This paper manages exploratory examination on mechanical properties of M30grade
concrete by adding polypropylene fibers in the blend at measurements of 0.5%, 1%, 1.5%, 2%, 2.5% by weight of cement
added to the mix. A comparative analysis has been carried out for conventional concrete to that of the fiber reinforced in
relation to compressive, tensile and flexural strengths.
