Performance Evaluation of Super-Pave and Marshall Mix Design to Suite Indian Climatic and Traffic Conditions

In India, presently the bituminous mixes are designed based on empirical laboratory procedures i.e. Marshall method of mix design without simulating the actual field conditions. This has led the highway engineers to think of a performance based mix design method, which can predict the fundamental properties of bituminous mixes such as rutting and fatigue. The primary objective of the performance based mix design method to establish the appropriate amount of binder content in the mix that will simultaneously satisfy the rut resistance and fatigue cracking requirements for given traffic and environmental conditions. This lead to development of Superior performance pavements (Super-pave) mix design by Strategic Highway Research Program (SHRP), USA. The main objective of the study is to develop performance based mix design for Indian conditions using Super-Pave Gyratory compactor (SGC) and compare the Super-pave asphalt mixture design procedures with the Marshall Asphalt mixture design method. The comparison was based on several issues including evaluation of materials prior to mixture design, the design asphalt content, and the relationship between mixture design and pavement performance. After comparison between mix design methods resilient modulus of different bituminous mixes prepared with conventional as well as modified binder, are evaluated at different temperature. For performance deformation of mixes, flow number test is performed through Asphalt Mixture Pavement Tester (AMPT) at varying air voids and at different deviator stress level. It is found that the performance parameters such as ITS, TSR, Resilient modulus and Flow number values are higher in case, sample prepared by Super-pave mix design method as compare to those sample prepared by Marshall method of mix design.
