The study here presents few laboratory test conducted on two closely spaced square footings on unreinforced and geogrid reinforced crusher dust. Model test was conducted on crusher dust with relative density at loose state condition taking different combinations of reinforcement layers of continuous and discontinuous pattern to find their interference effect. The study was carried out to evaluate the effect of spacing of footings, optimum number of reinforcement layer and also the effective reinforcement configuration. The interference effect on bearing capacity was studied on reinforced crusher dust and was compared with the unreinforced condition. It is observed that the inclusion of reinforcement below footings increased the ultimate bearing capacity. The bearing capacity ratio (BCR) is increasing with an increase in spacing between footings. Three layers of geogrid with bottom layer continuous and top two layers discontinuous are found out to be the most effective compared to two layers of reinforcement (bottom continuous and top discontinuous) showing a percentage variation of 23 and 16.7% at 2B and 2.5B spacing whereas compared to another three-layer combination of geogrid (bottom two layers continuous and top one discontinuous), it is varying with 11.6 and 7.6% for the same range of spacing between footings.
