Presently, India holds second largest roadway transportation mode network globally, in which about two third belongs to low to medium traffic class. Still, due to ageing effect, fatigue & dynamic loading and fund allocation problems affects the serviceability of this type of road networks. Numerous studies indicated that calcium predominant aggregates typically have better stability with stripping proof but lack in skid resistance due to polishing effect under traffic leading. Likewise, silica predominant aggregates have better proofing in skid but lack in stability and stripping. This study was fully focused on examine performance of asphaltic blend containing calcium and silica-based aggregates as fine and coarse aggregate in flexible pavement under low to medium traffic loads condition by conducting various laboratory tests. For aforesaid goal, three type of asphaltic mix was prepared, in which first mix contain calcium-based aggregate; second calcium and silica based aggregate and; thirdly silica-based aggregate as a fine and coarse aggregate respectively. Keywords:- Calcium based aggregates, silica based aggregates, asphaltic mixes INTRODUCTION Road Infrastructure is backbone for economic development and rapid industrialization of a nation. A fair road infrastructure is economic and long lasting in terms of strength and performance point of view. Roads in India are primarily bitumen-based flexible macadamized roads. Flexible road is composed of various layers comprising subgrade course, subbase course, base course and surface course. Surface course and base course consist of hot mix asphalt while subgrade, subbase conventionally consists of non- bituminous materials like sand and aggregates (IS 2720, Kent County Council, 2000). Load transfer pattern in flexible pavement is grain to grain, various layers in flexible pavement are capable enough to bear load transferred by subsequent layers. Any undulation and failure in subgrade and subbase reflect as failure in pavement during its service life, hence it is recommended good quality control and selection of best quality of aggregates or combination of different aggregates available locally. Due to limited availability of natural dimension stone aggregates different are attempt to use various stone waste in construction of pavement layers. Nowadays lots of laboratory study available to use of construction and demolition waste (C&D) as partial replacement of conventional aggregates for granular subbase (GSB). C&D waste obtained from crushed clay bricks and blocks are investigated by De Melo et al., 2013 and found satisfactory
