• Abstract:
  This report is the final report of this research project. It describes a compiling of materials utilized by various agencies for use in formation of inductive loop detectors. It further lists methods by which different agencies install materials in order to obtain a resilient detection system. Tested were loop sealants, loop wire, preformed loops and loop sawslot cleanout methods. Included is a "Results of Survey" chart depicting materials and methods used by eight states. It was found that though many different materials and methods are used to form inductive detector loops, there exist some major problems. These are, most commonly, loop sealant failure (loss of adhesion) and poor installation technique (inadequately cleaned sawslots).
