Abstract: A survey of ongoing research on bottom ash appears to demonstrate it has the ability to improve asphalt pavement performance when used to supplant a segment of the aggregate in asphalt mixes. Bottom ash can be utilized as an aggregate substitution, giving a considerable reserve funds to both highway organizations and service organizations. Bottom ash has been utilized as fine aggregates in flexible pavements since the mid 1970’s. The American Coal Ash Association detailed that, more than 17,200 metric huge amounts of bottom ash was utilized in flexible pavements clearing during 2006. The research is centered around examination of properties of bottom ash, which is the byproduct of Budgam coal power plant and attainability investigation of utilization of bottom ash in flexible pavements of indian roads. As indicated by the outcomes got, the best blends are delivered by mixing bottom ash with well-graded, angular, rough textured aggregate and restricting the level of bottom ash to 25% for wearing and 16% for binder course. Marshall Stability and flow values have been found to diminish as the level of Wet bottom ash is increased in the blend. Further, high level of bottom ash substitution increases ideal bitumen content, which primarily influences to high production cost. In spite of the fact that the expense per 1 Mt of bottom ash mixed blend is higher than the conventional mix for both surface courses, its low density increases overlay zone. In light of that the expense per 1 m2 is lower than the conventional mix. The fruitful utilization of bottom ash in black topped pavements in Jammu and kashmir would give huge monetary investment funds as well as an ecological inviting solution for a waste material.
