COMPACTION BY BLASTING

The technique of using explosives to achieve compaction of a soil mass has been tested in connection to a road construction project in the central part of Sweden. The natural soil, 2 to 3 meters (6.5 to 9.8 ft) of organic soil (peat), was excavated and replaced with a fine grained till. The test site was instrumented with pore pressure gauges, inclinometers and a device for settlement measuring. The fill was subjected to compaction by blasting on three occasions, each blasting separated by, at least, 2 to 3 weeks. To obtain the fill stiffness determination of Raleigh wave traveling velocities were carried through using the SASW (Spectral Analysis of Surface Waves) technique. These measurements were carried through on three occasions with the aim of detecting changes in stiffness due to the "compaction by blasting" activities.
