In India, power generation is one of the biggest sectors. Also, most of the power generated in thermal power. The thermal power generation is mostly based on coal. Also, this process involves the combustion of coal which generates fly ash as a by-product. This fly ash requires serious disposal. There are various methods adopted for this in India. One method which is not very well popular is using this fly ash along with a little number of additives in the construction of mine haul roads. The material which is used currently for mine haul road construction is locally available mine refuse. The current practice poses some serious problems, the solution of which can be found from the fly ash composites. Thus compressive strength of fly ash composites was tested. For this, the additive selected for strength gain was lime. Thus composites having different compositions were tested for their compaction characteristics and at their Optimum Moisture Content, the samples were cured for different periods and their compressive strength was tested. The results are analyzed. All of the samples developed were suitable for use in mine haul road.
