Bituminous Concrete mix design emphasizes to determine the proportion of bitumen, filler, fine aggregates, and coarse aggregates to produce a mix which is workable, strong, durable and economical. Bituminous concrete mix is the most common material used for flexible pavement road construction. It primarily consists of bitumen binder and aggregates. Bitumen binder acts as an adhesive agent that binds aggregate particles into a cohesive mass. One thing is of major considerations in this regard –pavement design. Our project emphasizes on the mix design consideration to find out the optimum binder content. In this design we have studied Marshall Stability test method. Keywords – Bitumen, Aggregate, Bituminous Concrete, Optimum Binder Content, Marshall Stability I-INTRODUCTION - Most of the roadways in India constructed with flexible pavement having surfacing course with bituminous concrete. Bituminous concrete should be constructed to satisfy the recommendation and requirements of Ministry of road transport and highways Section 509. This clause specifies the construction of Bituminous Concrete, for use in surfacing and profile corrective courses. During 1900’s, the bituminous paving technique was first used on rural roads – so as to handle rapid removal of fine particles in the form of dust, from Water Bound Macadam, which was caused due to rapid growth of automobiles [Roberts et al. 2002]. At initial stage, heavy oils were used as dust palliative. An eye estimation process, called pat test, was used to estimate the requisite quantity of the heavy oil in the mix. By this process, the mixture was patted like a pancake shape, and pressed against a brown paper. The first formal mix design method was Hubbard field method, which was originally developed on sand bitumen mixture. Mixes with large aggregates could not be handled in Hubbard field method. India being the second largest growing economy in the world, in par with other developmental activities, road infrastructure is developing at a very fast rate. Large scale road infrastructure developmental projects like National Highway Development Project (NHDP) and Pradhan Manthri Gram Sadak Yojna (PMGSY) are in progress. The spurt in the growth of traffic and overloading of vehicles decreases the life span
of roads laid with conventional bituminous mixes. This also leads to the
reduction in the riding quality resulting in exorbitant vehicle operating costs and frequent maintenance interventions due to premature failure of pavements. Providing durable roads has always been a problem for a country like India with varied climate, terrain condition, rainfall intensities and soil characteristics. A good amount of research is going on all over the country in this field to solve the problems associated with pavements. It is observed that Stone Matrix Asphalt mixture is an ideal mixture for long lasting Indian Highways. The literature pertaining to the bituminous mixtures is reviewed in this chapter with a detailed discussion of SMA mixtures. Several research studies investigated the role that aggregate gradation plays in the performance of asphalt mixtures-
