Abstract: Bituminous mixes are most commonly used all over the world in flexible pavement construction. Traditionally aggregates, sand, bitumen etc. are used for pavement construction. Commonly quarry dust is used as filler material in pavement work. Quantity of these conventional materials is reducing gradually. Also, cost of extracting good quality of traditional material is increasing. Concerned about this, we are looking for alternative materials for pavement construction, and Industrial waste materials such as Foundry Sand are one such category. If these materials can be suitably utilized in pavement construction, the disposal and pollution problems may be reduced. These industrial wastes occupies large amount of space around plants throughout the country. Keeping in mind the need for bulk use of industrial wastes in India, it was thought an expedient to test these materials and develop specifications to enhance the use of these industrial wastes in pavement construction, from which higher economic returns may be possible. Various percentages (0, 25, 30, 35, 40, 50, and 75%) of Foundry sand were used, and the proposed mix designs for bituminous concrete mix were conducted in accordance with Marshall Mix design. The experiment results revealed that the addition of Foundry Sand has a significant improvement on the properties of bituminous concrete mix.
