ASCE Emerging Concepts for the Design of Pipeline Renewal Systems
The Emerging Concepts for the Design of Pipeline Renewal Systems developed out of the efforts of the ASCE Task Committee authorized by the ASCE Pipeline Division’s Pipeline Infrastructure Committee (PINS). It includes previously published ASCE papers presenting this topic.
During 1999 the PINS Committee formed the Task Committee for evaluating the current calculation methodologies for determining renewal liner design. It was determined by PINS Committee during the 1990's and culminating in 1997 that the calculation systems were conservative as employed. During January 1998, also an International Trenchless Technology Research Colloquium at Louisiana Tech University determined that a new calculation methodology should be developed.
The commonly used “Fully Deteriorated” calculation system was based on the model used for trench installation of Fiberglass Pipe. The evaluation of this model was of prime concern to the Task Committee. It was quickly determined that the so-called “Fully Deteriorated” concept should be revised and basic fundamentals be researched, reviewed and incorporated into a proposed report. This task was completed and a synopsis is provided in this Committee Report.
Several international and domestic experts directly or indirectly provided input that is shown in this report. An independent “Blue Ribbon Committee” selected by the Pipeline Division has reviewed the contents of this report to ensure an acceptable consensus of industry professionals working in the pipeline rehabilitation (renewal) area, i.e., research, design, and construction, is presented.
