Abstract
Flexible pavements with bituminous surfacing are the most common Pavement Structure in India due to its fast and relatively simple construction. Stone aggregates are the most extensively used natural resource in Infrastructure development. The Present Flexible pavement design guidelines in India largely rely on use of stone aggregate for various courses. In view of the extensive and enormous road construction activities taking place in the country, which consume substantial natural resources and also availability of aggregates in high use urban areas is very less because of restrictions on mining, hence there is a strong need to incorporate alternate or waste materials in the construction. In the present study, an attempt is made to utilise Industrial wastes such as Phosphogypsum and GGBS as mineral filler by replacing conventionally used Stone dust in the Bituminous Concrete mix prepared using VG-30 and PMB-40 as Binders by adopting Marshall method of Bituminous mix design. Indirect Tensile Strength Test and Moisture Susceptibility Test are conducted on bituminous concrete mixes and it is observed that Bituminous Concrete mix with PMB-40 as binder and GGBS as mineral filler is superior in terms of Marshall Properties, ITS and TSR when compared to other Bituminous Concrete mixes.
