This paper contains an extensive study on the “Super Pave Mix Design” method which is used in the “Advanced Pavement Design” Technique. It helps in study and characterization of asphalt mixtures which are used as road pavement materials. By using the state of art laboratory test equipment and the technical literature obtained from the different information sources the several aspects of asphalt concrete mixtures has been expressed. This paper is divided into various parts. In Part one the detailed analysis of performance characteristics of asphalt concrete mixtures and design procedure is present with analytical method of aggregate blending which is used to design the aggregate structures. In part two the comparison between the Superpave and Marshall Stability hot asphalt mix designs have done. Various materials like: Coarse aggregates, fine aggregates, Bitumen etc. are considered for the Selection of materials on the basis of their properties. Such that the aggregates are selected on the basis of their various properties like strengths, soundness and shapes etc. On the basis of gradation aggregates sizes of 12.5mm and 20mm were designed for high traffic level whereas, 10mm were designed for low traffic level. There are different type of binders have been selected according to the traffic mixtures, PG 76-22M was selected for heavy traffic volume mixtures and PG 70-22M has been selected for low traffic volume mixtures. As it was given as PG-T1-T2 where T1 is considered as the maximum temperature value in degree Celsius and T2 is considered as the minimum temperature value in degree Celsius. After the selection of the suitable materials the design mixes have been prepared (Superpave Mix and Marshall Mix Designs) and further analysis has been done on the basis of following tests: Indirect Tensile Modulus Test, Uniaxial Loading Strain Test (Creep Test), Dynamic Modulus Test. The result of this paper suggests that dense aggregate structures provides good resistance to rutting behavior and maintained the adequate levels of durability. Such that this kind of mixes have to be developed to increase the resistance towards permanent deformation and to increase the durability.
