Abstract


Background/Objectives: In all over India, the bituminous mixes are designed based on the fulfillness of laboratory standards. The existing method is not focusing on field condition, they simulate only time based requirements. Methods: To improvise the quality and performance of bituminous mix, the product of SHRP asphalt research program has developed a new system called Superpave (Superior Performance Pavements). Superpave design mix will optimize the asphalt mixtures resistance in deformation, fatigue, cracking and rutting. The Superpave system was created to make the best technology to suit the environmental condition with the better performance compared to Marshall Methods. Findings: In Superpave design only 10% of flat and elongated aggregates are acceptable. The main objectives of this study to develop, the performance based design mix for Indian condition using Superpave graded bituminous mix. This study is mainly focusing on the Superpave graded bituminous mixes. The various factors such as, Stability, Flow, Voids in Mineral Aggregates (VMA), Voids in Filled Bitumen (VFB) and Air Voids (Va) are compared with Marshall hammer and Hugo Compactor. Applications/ Improvements: In this Study it suggest that, the using of Hugo Hammer gives improving in strength and Increasing effects in Volumetric Analysis.
