Mobile Runway Edge Sheave Anchor Criteria in Asphalt Concrete Pavement

Abstract: The Mobile Runway Edge Sheave (MRES) is used in conjunction with the Mobile Aircraft Arresting System (MAAS) for setback aircraft arresting system (AAS) installations in expedient or temporary situations. There are existing criteria and tactics, techniques, and procedures (TTPs) for MRES installations on portland cement concrete (PCC) pavement and soil, but these criteria have not been developed for asphalt concrete (AC) pavements. The US Air Force Civil Engineer Center (AFCEC) tasked the US Army Engineer Research and Development Center (ERDC) to develop anchor criteria for the MRES in AC pavement and to perform full-scale load testing on the MRES to evaluate system response under representative loads. Three anchor stake layouts were evaluated under static and cyclic loading conditions: a 32-stake layout, a 16-stake layout, and an 8-stake layout. Elastic-plastic deflection data from the three test series were comparatively analyzed and show that the performance of the 16-stake layout was similar to that of the 32-stake layout for the given loading condition and pavement structure.
