Installation of pipes in urban areas requires a pipe product possessing high strength and pressure ratings which can be used with laying techniques causing minimum surface disruption. This thesis reviews trenchless pipe laying techniques and presents the findings from a detailed study concerning the mechanics of the pipe bursting process. The development of a new ductile iron joint for pipe bursting applications was undertaken and testing of the joint in the laboratory and in the field is described in detail. [Continues.]
