Abstract:

The report describes results of an investigation conducted to evaluate an experimental, commercially fabricated, plastic landing mat designated the T13. It is a sandwich structure made of glass-fabric-reinforced phenolic resin honeycomb core bonded top and bottom to glass-fabric-reinforced epoxy resin facings. The investigation consisted of laboratory tests to determine the structural properties of the mat and engineering traffic tests to obtain information for use in comparing the performance of the T13 plastic mat with that of the 10-gage M8 steel mat and with project requirements. The tests revealed a major deficiency in the strength of the adhesive bond between the extruded aluminum connectors and the facings of the T13 mat. Other structural properties of the mat, such as tensile, compressive, and flexural strengths of the facings and panels, were close to the desired values considered necessary to meet project requirements. The adhesive bond connection between connectors and facings was supplemented by a riveted type of connection. The T13 mat then sustained 350 coverages of a 50,000-lb single-wheel load and 200-psi tire pressure on a 14-CBR subgrade. Author
