Bituminous mixes are used in flexible pavement construction. It consists of asphalt or bitumen (used as a binder) and mineral aggregate which are mixed together, laid down in layers and then compacted. Fly-ash is disposed very casually, which may cause serious health and pollution problems. Which may lead to adverse effects on the environment. To deal with this problem, here to investigating an effect of use fly-ash as an alternative to conventional material in dense bituminous macadam layer of flexible pavement. In Literatures, there are various tests which have been carried out by replacing fine aggregate fly-ash. The results obtained by laboratory investigation indicate major gain in strength with substantial saving in cost. Marshall Stability Test is a very important test for the bituminous mixes in flexible pavement.
