This report describes a multifacted investigation into the application of lime slurry pressure injection (LSPI) to stabilize and improve railroad roadbeds. Areas discussed include (1) the current state of lime-injection technology, (2) soil exploration and testing related to the use of LSPI, (3) costs of roadbed stabilization by the LSPI method, (4) Environmental aspects of the track-roadbed structure. In addition, summaries to two types of ancillary reports are included: (1) those resulting from case studies of several specific lime-injection projects and (2) those describing independent research work involving either the lime-soil combination or finite element analysis of the track-roadbed structure.
