Abstract: The tremendous usage of virgin asphalt and aggregates is leading to their exploitation as a resource. There is a great importance to use the ruined pavement materials which causes various environment hazards and creates disposal problems. The main purpose of this study is to use the higher proportion of recycled asphalt pavement mixtures for road construction in a national highway project. The percentage of Recycled Asphalt Pavement (RAP) is taken at a range of 10% to 50% and then doing various tests related to strength and check the best one percentage of Recycled Asphalt to be used in road construction. The main scope of this study is to reduction in material cost, energy cost and also total job cost. This is done as RAP involves reuse of materials so the above all cost reduces. Through this the amount of bitumen content present in the RAP is calculated. Today the reduction on the dumping of reusable materials is increasing. So, in future there is very high possibility of ban on their disposal into landfills. So that is the reusing of bituminous material show to sustainable development. An effort is done to achieve the stabilization of asphalt by performing different tests on bitumen and aggregates as per MORTH specification. Furthermore, an attempt was carried out through Marshall Stability Test to examine the all Marshall values mainly the load and flow rate of asphalt specimen by using manual compaction and conditioned in a water bath at a specified temperature. This paper presents research to study the behavior of mixture of asphalt with RAP. Finally, a guideline that is selected from the reference sample to be in service of access the higher proportion of RAP and the optimum value of modified sample.
