A Review on Rigid Pavement by Using Alternative Material

Abstract

A considerable number of concrete pavements already exists on roads across the globe. Additionally, although asphalt pavements are now more prevalent, concrete pavements offer several unique uses. In addition, asphalt is a resource that is being used up at a quick pace, which might indicate that concrete will be the dominant material in the future. Yet, there are a few downsides to using concrete pavements, such as the high cost of construction, limited tensile strength, and substantial contribution to global carbon-di-oxide emissions. This research intends to remedy these shortcomings by surveying the most popular substitutes for cement and aggregates in concrete. We look at the possibility of using substitutes such fly ash, recycled concrete aggregate, coal ash, nano-silica, and silica fume. Plus, we go over what happens when you mix fibers into concrete pavements, whether in the form of fiber-reinforced concrete or engineered cementitious composite. Researchers and pavement engineers may also use this evaluation to determine the best material combination for improved mechanical qualities compared to regular concrete. While there has been a recent push by the government to find new uses for solid waste in an effort to lessen its negative effects on the environment, there has been very little effort along these lines in the Indian setting. Heavy traffic may be safely accommodated on rigid pavements, which are usually constructed of concrete due to their long lifespan and exceptional strength. While further research may be necessary to address the workability problem, this study provides a summary of global studies that have used several alternative materials to partially replace aggregates and cement.
