Effect of an innovative vertical vibro-tracked vehicle on soil compaction

The aim of this paper is to compare a new vertical vibro-compaction machine, carried by a tracked vehicle of total weight 10.9 kN, with compactors using centrifugal, vertical and horizontal oscillators at the exciting force of 9.8 kN and at a frequency of 16 Hz. These were tested experimentally on a thick lift of decomposed weathered granite sandy soil. It was observed that the final amount of sinkage of the terrain surface using the vertical vibro-tracked vehicle was the greatest. The final distribution of dry density was almost uniform in depth and the values were the largest of all other maximum dry densities for centrifugal and horizontal vibro-tracked vehicles. As a result, the vertical vibro-tracked vehicle was verified theoretically from the analysis of the stress and the acceleration propagation to be an excellent and impressive new compaction machine for compacting thick lifts of soil stratum.
