Title:            Cost analysis of low volume rural roads using rap materials as G. S. B.
Authors:       N. Sreedhar, K. M. Mallesha
Abstract:     Reclaimed Asphalt Pavement (R.A.P.) is the most and abundant Industrial waste available due to expansion and upgradation of the existing asphalt roads like Major District roads(M.D.R),State highway(S.H) and National Highways(N.H).Since the quantities available is more which makes Highway and Tranportation Engineers to find solution to reuse the RAP materials and thereby consuming the Industrial waste and conserving the natural resources. Reusing of RAP materials in the G.S.B. will also saves the construction cost by 25-30%. Various techniques have been devised for finding the characterization of the RAP materials by conducting lab tests for Aggregates as well as for the Bitumen. The thickness of the Pavement is designed on the traffic volume to maximum of 450 CV per day. The Pavement is designed by C.B.R. chart with least CBR value of 8% and overall thickness is calculated as 350mm with 150 mm Subgrade, 175mm GSB layer and 25mm SDBC layer. Cost analysis is done for a stretch of 5 KM and saving of 35% is achieved. Characterization of RAP materials helps in finding the deficiency which can be blended with new natural aggregates which satisfy the Morth specification. The pavement is made with following standard specification for Subgrade to maintain 95-98% dry density using Compaction roller .Similarly the GSB layer is compacted according to IRC specification and other IS codes. This paper presents the outcome of a laboratory study of SH- 3,on a 60 KM stretch between Maagadi and Koratagere. Experimental investigation encompasses tests on Atterberg Limits, Free Swell Index, Compaction Characteristics, CBR tests for Subgrade. The tests were carried out on RAP material, like Bitumen demand, Gradation, CBR test for GSB material as per relevant IS Codes.

Keywords:      RAP, G.S.B layer, SDBC, CBR, compaction.
