Existing structural design guidelines for cured-in-place pipe are both vague and conservative, resulting in a significant under-utilisation of this important sewer rehabilitation technique. This proposal is a collaborative research programme which aims to address this issue. An extensive series of geotechnical centrifuge tests will be undertaken at Cambridge University on simulated soil-pipe systems subject to ground and traffic loading in both the deteriorated and renovated conditions. The effects of variable water table, progressive host pipe deterioration, voids in the backfill and high intensity traffic loading will be evaluated. This will provide new information on the mechanics of soil load transfer onto inner lining pipes. At Bradford University earlier work on the performance of linings subject to external groundwater pressure will be extended to include an improved design model and supporting laboratory test data for the creep buckling of circular systems. A fracture based material model will be developed and incorporated in a fully consistent numerical analysis of non-circular pipe systems; the results will be compared with laboratory test data.The results from both programmes of research will be of direct use to practitioners, by providing improved design guidance for flexible pipe linings used for rehabilitation of deteriorated sewers.EngProg\
