Load carrying capacity of reinforced pond ash beds

Abstract

experimental study is taken up to improve the strength of compacted pond ash. This has been achieved in two series of tests. In the first series of test the compacted pond ash beds are reinforced with either PVC net or GI nets. The size of the reinforcement as well as the position of the reinforcement was varied. The CBR value of these specimens we are found out and these are compared with that of and unreinforced pond ash bed compacted to MDD at OMC. In the second series of the tests the CBR value of river sand compacted to different relative densities and different moisture contents are evaluated. In general the CBR value of compacted sand at different moisture content are found to be higher than compacted pond ash. To find out the CBR values of compacted pond ash beds overlain by a layer of sand with different relative densities and moisture contents. The optimum thickness of sand beds has been found out such that effect of underlain pond ash beds is minimal on the CBR value based on these experimental results it is concluded that in filed the bearing capacity of ash beds can be improve either by reinforcing it with suitable gird reinforcing materials are by overlaying it with suitable thickness of stiffer material such that the effect of under laid Pond ash material is not felt.
