Recycled Asphalt Pavement, more commonly known as RAP, has been a popular alternative for the materials used in the construction of roads. Road construction utilizes millions of ton of natural resources over the years. By reusing the materials from the original pavement money, time and space for material used is saved. When we recycle the materials of the pavement the integrity of the materials may be lost due to construction conditions. This paper intends to study the properties of Pavement recycling (RAP material used again in base layer) and the effect of the larger sized aggregate which are obtained from the different milling rate. As different milling rates produce varying degree of fineness, the material results in varying strength of Base layer pavements obtained from different milling rates. Also, during actual construction process, the milled aggregates are mixed with stabilizing agents and compacted on site; this study aims to determine the capability of Recycled RAP as base layer to meet the strength and performance requirements of base course layer of pavements and to analyse the variations of these properties in the different pavements produced. This would help to encourage the reuse of RAP in pavement construction.
