Use of Discrete fiber in road pavement

Abstract

Concrete roads are very linear, linear route meansa route that progresses from a starting to an ending point. The beginning and end of a linear route do not meet, but may connect to another route or a destination point and can provide a safe and smooth flow of traffic. Due to the use of concrete in roads it has become quite an advantage for a greater life span and low maintenance. But concrete roads may undergo cracking, spalling and concrete is weak in tension and also little ductility. So as to reduce these problems Inclusion of fiber can provide a great benefit to concrete pavement. This Research “The Use of Discrete Fiber in Road Pavements” is done so as to improve the quality of concrete pavement. In this research the fiber used is polypropylene fiber and polyester fiber. The concrete mix used is M25. (Nominal mix ratio of m25 grade of concrete is1:1:2, mixture of cement, sand, aggregate and water in which one part is cement, one part is sand and two part is aggregate and water cement ratio is 0.4 to 0.6.0). In one specimen only plain, concrete mix is tested for compressive strength, flexural strength and split tensile strength. In second specimen 1.8% of polypropylene fiber is added with the concrete mix and again tested for the same three tests. In the third sample 0.5% of polyester fiber is used in the concrete mix and tested for compressive strength, flexural strength and split tensile strength. In fourth specimen both 1.8% of polypropylene fiber and 0.5 % of polyester fiber is mixed with the concrete mix and tested for the three tests It was seen a large increment in the strength which showed the addition of fiber can improve the quality of concrete.
