ABSTRACT

Design construction and maintenance of roads are given prime importance in the development of the infrastructure of a country. High traffic intensity in terms of overloaded commercial vehicles, significant variations in daily—seasonal temperature and extreme environmental conditions contributes to early development of distress in pavements. The objective of this research study was to evaluate moisture susceptibility of hot mix asphalt modified with nano-organosilane as an anti-stripping additive. The study was also focused to evaluate the influence of different fillers collected from local sources on the performance of asphalt mixtures. The different types of fillers (Quarry dust, Silica fume, and Fly ash) added in different proportions to study the performance of the mix. The Marshall Stability value was increased by 30% of the control mix. Indirect Tensile Strength and Stiffness Modulus values for modified mix were also found increased. Rut depth was decreased for modified mixes up to 47%.
