Abstract: Road network in India aggregates to about 4.2 million kilometers, which is second largest in the world only after USA. National Highways (NH) constitute about 70,934 kilometers which is only 2 percent of the total road network. State Highways (SH) and Major District Roads (MDR) together constitute the secondary system of road transportation which contributes significantly to the development of the rural economy and industrial growth of the country. Hence, construction of roads has led to increase the pressure on natural resources. For sustainable development, it is therefore desirable to implement the reuse and recycling techniques in road construction. Using Reclaimed Asphalt Pavement (RAP) in bituminous mixes is one such technique. This paper presents the effect of addition of RAP on Dense Bituminous Macadam on the basis of Marshall Stability Test. The mix having RAP percentage of 25% and 30% showed better results when compared to control mix.

Keywords: Dense Bituminous Macadam, RAP, Marshall Stability Test, Flow Value.
