Abstract—Fly ash is a waste produced mostly from the burning of coal in thermal power stations, which contributes to environmental pollution. Also, a number of studies have been conducted to investigate the influence of randomly oriented fibers on the engineering behavior of coarse grained and finegrained soils. The influence of randomly oriented polypropylene fibers on the engineering behavior of soil fly ashmixtures has not been reported so as much detail as in the case of the soils. The purpose of this investigation was to identify and quantify the influence of fiber variables (content andlength) on performance of fiber reinforced soil- fly ashspecimens. A series of laboratory unconfined compression strength tests and California bearing ratio tests were carried.Polypropylene fibers with different fiber length (6mm, 12mmand 24 mm) were used as reinforcement. Soil -fly ashspecimens were compacted at maximum dry density with low percentage of reinforcement (0 to 1.50 % of weight).Four primary conclusions were obtained from this investigation.First, inclusion of randomly distributed fibers significantly improved the unconfined compressive strength of soil fly ashmixtures. Second, increase in fiber length reduced the contribution to peak compressive strength while increased the contribution to strain energy absorption capacity in all soil flyash mixtures. Third, an optimum dosage rate of fibers was identified as 1.00 % by dry weight of soil- fly ash, for all soil flyash mixtures. Fourth, a maximum performance was achieved with fiber length of 12mm as reinforcement of soil fly ashspecimens
