Transportation contributes to the economy, industrial, social and cultural development in country. Transport demand in most Indian cites has increased substantially due to increases in population as a result of both natural increased and migration from rural and small town. In the Ahmedabad BRTS traffic at intersection and bus-stand is most serious problem for BRTS buses. Non-destructive structural evaluation of pavements is an important part of the pavement management.In this research,emphasis has been laid on the non-destructive Structural Capacity Evaluation and pavement distress identification. Visual survey on the station like Maninagar, Swaminarayan Mandir, Danilimda, Chandranagar, Nehrunagar and Memnagar. I had found pavement failures like rutting and fatigue failure at BRTS routes. I measured rut depth of pavement. For the solution of this problem I am planning to use Jute fibres in wearing course of pavement. Stone Matrix Asphalt (SMA) is a gap graded mix, characterized by high coarse aggregates, high asphalt contents and polymer or fibre additives as stabilizers. High concentration of coarse aggregate maximizes stone-to-contact and interlocking in the mix which provides strength, and the rich mortar binder provides durability. The stabilizing additives composed of cellulose fibres, mineral fibres or polymers are added to SMA mixtures to prevent drain down from the mix. In comparison to dense graded mixtures SMA has higher proportion of coarse aggregate, lower proportion of middle size aggregate and higher proportion of mineral filler. It resists permanent deformation and has the potential for long term performance and durability.
