Abstract

In our country one of the major distresses is due to the rain induced damages. It is a well established fact in developed countries that the water induced damages are expected to be less in a gap graded mix like stone matrix asphalt than traditional mixes. But application of SMA in India is very limited due to lack of proper specifications. Now a days, synthetic fibers, polymers are used as stabilizing additives in SMA. Here Sewage Sludge Ash (SSA) is used in Replacement of expensive imported synthetic fibers and polymer additives with renewable/waste material in SMA is an environmental necessity. Here, a study on the impact of waste material as addictives in Stone Matrix asphalt and their role in the volumetric and drain down characteristics of the mixture is proposed. Emphasis is also given to assess the effect of water immersion on the performance of SMA mixture with different additives. In the present study 60/70 penetration grade bitumen is used as binder and polymers are used as stabilizing additive. In this research sewage sludge ash as filler in SMA and their role to study the drain down characteristics of SMA at OBC and Marshall stability test to evaluate the stability and flow values when SSA is added as filler to OBC and OAC.
