The roadways in India is dominated by flexible pavements and the conventional bituminous mixes proves to be obsolete for the quantum loads exerted by the commercial vehicles which ply on the pavement. Superior quality of pavement is achieved by using superior grade of materials and proper quality control during construction. To modily bitumen, there are many commercially available chemicals which are claimed to be the best in the market to modify bitumen, but only few prove the worthiness. One such commercially available elastomeric pellet VIATOP plus FEP Das Pellet is used in this work and it is evaluated based on laboratory investigation. The rheology of the modified bitumen mainly depends on the percentage of dosage, the mixing temperature, the mixing RPM, and also the mixing process (Dry process or Wet process). The present study is aimed at obtaining the optimum dosage of the elastomeric pellets that has to be added to the neat bitumen, in order to get a superior bituminous mix. The study is conducted on VG-10 bitumen and VG-30 bitumen for both BC Grade-II and DBM Grade-II mixes. Performance studies, such as Indirect Tensile Strength, Moisture Susceptibility, and Repeated load test are done at obtained OBC using Marshall Criteria.
