Abstract:- The transportation network is a significant aspect in determining a country's success. Pavement is a fundamental component of transportation. Pavements are in poor condition in most nations, particularly in India. This is mostly due to inadequate road maintenance, the use of low-quality materials, and other factors. Potholes form on a pavement when it loses its capacity to convey traffic weight to the subgrade. The transportation industry is constantly expanding. This results in a significant rise in the number of cars, which increases traffic congestion. Existing pavements are incapable of bearing this increased strain. The traditional materials utilised in pavement construction are unable to withstand the heavy traffic load. It signifies that there is a need to increase the strength, quality, and other characteristics of the pavement mix. The inclusion of fibres is one of the simplest and most efficient ways to accomplish this. The fibres enhance the mechanical, rheological, and volumetric qualities of the mixtures. Some obvious benefits are increased fracture resistance, durability, adhesion, and flexibility. This research examines how the characteristics of pavement mixes change when they are amended with synthetic fibres, natural fibres, and mineral fibres. Changes in pavement mix parameters such as Marshall stability, flow value, indirect tensile strength, Marshall quotient, VMA (voids in mineral aggregate), VFA (voids filled with asphalt), drain down values, and so on have been investigated. Mixtures containing fibres provide improved impact resistance, a reduction in traffic abrasiveness, and a delay in the initiation and propagation of fractures.
