Improving the Performance of Cement Concrete Pavement by using Polypropylene Fibers

Abstract

India is a leading country in terms of infrastructure development in the world. In future use of high-performance concrete which are durable is required for construction of roadways. Polypropylene Reinforced Concrete is concrete containing polypropylene fibers which increases the structural integrity. The characteristics of Polypropylene Reinforced Concrete changes with varying fiber geometrics, distribution, orientation and densities. Polypropylene fiber is a light weight synthetic fiber. It is expected that if the addition of polypropylene in concrete mix in a right proportion can help enhancing the concrete properties like strength, water resistance etc. Roadways being backbone of the transportation system it is very important that they are designed to last long should be able to resist wear and tear for longer period. If the Polypropylene Reinforced Concrete mix is used in the construction of Rigid pavement it will allow us to design high performance Rigid pavements which can last longer than regular concrete mix pavements at a same or less construction cost and the maintenance cost is also expected to be reduced.
