Abstract

A strong road system is essential for a nation's economy to develop quickly since it connects outlying locations to the rest of the country for use in many types of transportation. Reclaimed asphalt pavement (RAP) is a suitable substitute for virgin material since it lessens the requirement for virgin material. In this investigation, sample of recovered asphalt pavement was gathered and examined to determine whether it would work well as flexible pavement. In this experimental study, bituminous concrete mixtures containing 10%, 20%, 30%, 40%, 50%, and 60% RAP material were the focus. These mixtures were made by scarifying bitumen like VG-30, fresh surface aggregate, and damaged existing asphalt paving without the addition of any additives. In this research, the RAP to new aggregate rates were 10:90, 20:80, 30:70, 40:60, 50:50, and 60:40 . RAP mix was the subject of several laboratory tests, including the Marshall Mix design and many other Physical Properties tests, this paper presents a comprehensive investigation into the behavior of asphalt mixtures with varying proportions of RAP. Ultimately, guidelines derived from reference samples are proposed to facilitate the use of higher RAP proportions and determine the optimum value for modified samples.
