Abstract: This paper presents economic evaluation of Plastic Cell filled Concrete Block Pavement (PCCBP) over conventional flexible and Concrete pavements for low volume rural roads. The cost comparison has been carried out considering both construction and maintenance cost for a period of 5 years, based on design analysis and performance studies of 100 mm thick PCCBP laid over 100 mm thick WBM sub-base course. It has been observed that the initial construction costs for both flexible and rigid pavement were higher than that of PCCBP by ~9% and~150% respectively and the total cost (including maintenance cost for 5 years) of flexible and rigid pavement are found to be higher by ~43% and~141% respectively as compared to that of PCCBP. Cent percent replacement of river sand in concrete by waste stone dust proved to be cost cutting without significant change in strength of the concrete.
