RECYCLING OF FLEXIBLE PAVEMENT

Abstract

One of the most crucial parts of any project's design is the pavement. The part of the road that stands out most to drivers is the pavement. The degree to which the pavement is smooth or coarse is often used as a measure of the highway's condition and sufficiency. Poor pavement conditions may raise the likelihood of accidents, increase fuel consumption and brake forces, and lengthen travel times and associated expenses for users. The durability and longevity of the pavement are directly proportional to the material's strength and stiffness. Therefore, while designing pavement, it is important to prioritize the most cost-effective and efficient use of existing materials in order to maximize their performance. It is necessary to restore the roadways using environmentally friendly approaches in order to improve them for future generations, since the deteriorated pavements are left unmanaged. It is possible to create rehabilitation methods by researching different kinds of distresses, material circumstances, and environmental factors. Finding damaged pavement and creating a repair method using RAP material to enhance the road's fatigue life economically are the main topics of this research. The development and upgrading of existing asphalt roads, such as Major District Roads (M.D.R.), State Highways (S.H.), and National Highways (N.H.), produces reclaimed asphalt pavement (R.A.P.), the most prevalent industrial waste. The study begins with an overview of the topic and then moves on to a literature review, testing methodologies, bituminous mixture mix design, and finally, the design of flexible pavements. In order to increase strength while decreasing cost, the granular and bituminous layers employ 30% RAP.
