9. Conclusion
With a usage pattern of less than 58% in a year, 6% of which being in the road sector, and with around 67 million tonnes accumulating every year, a focus or strategic approach is required to increase the percentage utilization of fly ash in the road sector. The road sector in itself could be one of the major sectors for fly-ash utilization because of the size of presently ongoing road development projects in the country. The hierarchical structural model developed using the ISM technique spells out the approach or action plan for enhancing fly-ash usage in the sector. Alhough the factors discussed have been acted upon individually by concerned agencies, the model developed suggests that the methodology, if adopted, would accelerate fly-ash utilization in the sector.
Since the factors that are at the heart of the model are the main drivers, location-specific strategic plans bear the major onus of criticality of the whole model from an execution point of view. Such plans being in place, the remaining factors would demand attention, and hence it is suggested that the whole model be implemented in unison in order to achieve the best results in terms of fly-ash utilization in the road sector. Successful adoption and execution of the model is expected to establish an effective ecosystem with a focus on technology utilization towards maximum usage of fly ash in the road sector
