There is an enormous amount of investment involved in highway construction, and about 60 percent of highway construction costs are associated with pavement construction. Bituminous materials are commonly used for pavement construction, mainly due to their excellent binding properties, water proofing properties and relatively low cost. For bitumen concrete mixing, however, the strength of bitumen concrete depends on all the materials used in the mix model, i.e. bitumen, coarse aggregate, fine aggregate and filler. Mastic asphalt is potentially advantageous paving material and has gained wide acceptance in road construction technique. Therefore, there is a need to explore the use of various types of waste materials like Stone Dust, Marble Dust, Slag, Fly-ash, Brick Dust, Cement by Pass Dust and Rise Husk Ash, steel slag etc. The present study examines the effect of lime replacement in mastic asphalt preparation with fillers such as Fly-ash and Marble Dust and Fly-ash + Marble dust. Furthermore, the present study may reduce the cost of mastic asphalt, which is the main reason for its limited use, and may also enhance the properties of mastic asphalt as well as cater for industrial waste disposal such as; fly-ash and marble dust.
