Abstract

Superior performing asphalt pavement (SUPERPAVE) is a new system for specifying asphalt materials which includes selecting and specifying asphalt binders, detailed mineral aggregate requirements, in which a new laboratory compaction method is achieved by means of compactor called superpave gyratory compactor (SGC). SGC provides specimen that is much more representative of actual in service pavements which can’t be achieved by Marshall Method of compaction. Due to the variety of heavy vehicles and increase of traffic loads, the development of failures occurred at a faster rate, which created the need for modified binders to get an efficient asphalt mix. In the present work, Asphalt mixtures was prepared with Superpave gradation having nominal maximum aggregate size of 25 mm. the samples were prepared in SGC at three asphalt contents (4%,4.5%,and 5%) by weight of total mix for both VG 30 and PMB 40. Indirect tensile strength ,stability, resistance to moisture susceptibility and resistance to fatigue (repeated loading system) tests were conducted to evaluate the both mixes in which SP samples made with PMB 40 were superior compared to that of VG 30. Rural roads constitute an integral component of the road system in all countries. These encompass all aspects of the social and economic development of rural communities. It is known that on a worldwide basis the number of low traffic roads far exceeds the length of high volume roads. Across India, 90% of the roads are rural roads and they often from the most important link interms of providing access to educational, medical, recreational and commercial activities in local and regional areas. The vast expansion of the road network has brought connectivity to the rural areas of the country. Further, it is noticed that due to increasing axle loads and lack of timely maintenance, is accelerated the process of deterioration of rural roads.
