Black cotton soil (Silty loamy - CH) is one of the major soil deposit in India and characterized by high shrinkage and swelling properties. This BC soil occurs mostly in the central and western parts and covers approximately 20 % of the total area of India. Because of high swelling and shrinkage characteristics, the BC soil has been a challenge for the highway engineers. BC soil has very low bearing capacity. Soaked the laboratory CBR values of BC soils are generally found in the range of 2 to 4 %. Due to very low CBR values of black cotton soil excessive pavement thickness is required for flexible pavement. Reclaimed asphalt or recycled asphalt payment (RAP) is reprocessed pavement material containing asphalt and aggregate. There are many reasons to use RAP material including cost, the environment, and sustainability. Large length of asphalt roads in India the opportunity exists to really create environmentally friendly, sustainable projects using reclaimed materials. This research paper mainly focusses on investigate the use of reclaimed Asphalt pavement material in black cotton soil and to check the natural properties and behavior for the same. The present work is focus on MMGSY roads near Bharuch and soil sample was collected for various test to analyses the properties of BC soil and with additional RAP material. The tests results show improved CBR values. The optimum dosage of reclaimed Asphalt pavement materials decided which is represented in the paper.
