Verification of the effects of rolling dynamic compaction using a continuous surface wave system

Abdelmalek Bouazza and Derek Luigi Avalle

Abstract

Impact rolling or rolling dynamic compaction (RDC) has been used to redevelop the site of an old waste tip. The fundamental principle of RDC is a non-circular drum rotating about one corner and falling to impact the ground, while being towed at 10-12 km/h. Surface wave measurements show that the RDC has been effective in improving the strength of the material below ground surface. The successful application of the RDC resulted in a cost-effective and environmentally sustainable solution.
