This study is done to find out the maximum possible direct cost deviations in materials and construction of flexible road crust type among the five flexible road types cited in IRC 37-2012, So as to frame maximum baseline cost variation for optimization of cost and proper planning of construction at various CBRs from 2% to 15 % and different traffic volume conditions from 2msa to 30 msa. This analysis can be utilized for obtaining probable direct construction and material cost escalation or savings in project if in case the road crust type is required to be changed. The material, equipment and direct construction cost and their proportions for various types of flexible pavement are calculated based on the district schedule rates and the specification and standards of the Roads (MORTH Specifications). Minimal costing road pavement crust type is selected among all crust types and the cost deviation in direct cost of material and construction for remaining pavement crust types is found out, which could serve the purpose of selecting lowest construction costing road crust.
