Concrete is the most undisputable material being used in infrastructure development throughout the world. Natural sand is a prime material used for the preparation of concrete. The reduction in the sources of natural sand and in the cost of concrete production has resulted in the increased need to find new alternative materials to replace river sand, so that excess river erosion is prevented and high strength concrete is obtained at lower cost. The aim of the study is to minimizes the cost and achieve sustainable development of concrete pavement. Cement, sand and aggregate are basic needs but the new alternative materials that is tiles dust generated from tiles industry, about 15%-30% production goes as waste, these are partially replaced by river sand. The fine aggregate has been replaced by tiles dust accordingly in the range of 10% (TA1), 20% (TA2), 30% (TA3), 40% (TA4) & 50% (TA5) by weight for M-20 grade concrete. Concrete mixtures are produced to make (6 in × 6 in × 6 in) cube for compressive strength test at 7, 14, 28 days curing period and (4 in × 4 in × 20 in) beam for flexural strength test at 28 days curing period, tested and compared in terms of compressive and flexural strength with the conventional concrete. Maximum compressive and flexural strength are found for 10% replacement of tiles dust (TA1) with respect to the conventional concrete (A0). By using alternative materials, the strength of concrete is increased significantly and for showing cost effectiveness a concrete pavement from Talaimari MOR to Kalpona Cinema Hall is designed for 4500 commercial vehicles per day. The pavement thickness required for conventional concrete is 28 cm whereas the pavement thickness required for concrete TA1 is 24 cm. Since the thickness of pavement slab is reduced, the cost of pavement construction is reduced almost 15% for concrete TA1.
