Evaluating technology management factors for fly-ash utilization in the road sector using an ISM approach

Abstract

The generation of fly ash is supported by much effort to utilize it to the greatest extent possible. Present usage of around 58% of fly ash generated every year demands more effort. Around 6% of fly ash utilized is being used in road applications. More fly ash can be utilized in road sector because of its having huge potential mainly in embankments. Fifteen factors have been identified, studied, analysed, classified and presented as a model that suggests their significance towards accomplishing the objective of more fly-ash utilization in the road sector. Interpretive structural modelling (ISM) is applied to these factors to obtain their relative relationships. The key factor is local specific strategic planning, which is identified and recommended for implementation in the present scenario along with maintaining focus on all factors for successful implementation towards the desired objective.
