The North Field 87 Rapid Runway Repair Test, conducted at North Field SC, was a concurrent Developmental Test and Evaluation (DT & E) and Initial Operational Test and Evaluation (IOT & E) of four Rapid Runway Repair system. The DT & E portion of the test consisted of a Folded Fiberglass Mat Test and an Upheaval Measurement Test. The Folded Fiberglass Mat Test evaluated the performance of a folded fiberglass mat under aircraft trafficking. Two explosively formed craters were repaired with polyester folded fiberglass mats and trafficked with a maximum of 110 combined F-15 and F-16 aircraft passes. One mat was instrumented to record mat and anchor bolt loads during aircraft trafficking. Instrumentation results are reported in Volume II. Mat anchoring, hinge orientation, and mat reaction to jet blast were also examined. The upheaval measurement test evaluated three methods of determining upheaval. The standard stringline, modified stringline, and Dipstick pavement profiler were evaluated for speed and accuracy. The IOT & E tests, including the Hand-Mixed Polymer Spall Repair Test and the Minimum Operating Strip Marking Test, were conducted by the United States Air Force Tactical Air Warfare Center. (sdw).
As part of the USAF's program for developing systems and procedures to rapidly repair bomb-damaged runways, the Air force Engineering and Services Center conducted the North Field '87 Rapid Runway Test. This volume of the North Field '87 Test Report documents the design and installation of an instrumentation system to monitor mat response to F-15 and F-16 aircraft ground operations; data acquisition, processing, and reduction, finite-element modelling of the mat system; a comparison of predicted and actual mat response; and anchoring system reliability study. Keywords: Anchor bolts, Bolt loads, Bow waves, Rapid runway repair, Instrumentation, Mat strain, Shear stress, Strain gages, Fiberglass mats. (KR).
This technical report is divided into two volumes. Volume I contains the technical analysis and weather effects on RRR process, while Appendix A, Weather Data, is published as Volume II because of its size. This report presents the results of a study to identify the effects of weather on Rapid Runway Repair(RRR). There are two major components of the study. The first characterizes the aspects of weather that affect RRR, by area for Korea, Europe, and England. Graphs present data on temperature, precipitation, visibility, wind, and humidity. The second component studies the effects of weather on the RRR process. The process is divided into activities, with associated efficiencies under various weather conditions. Values for the efficiencies are developed from military and industrial data. The two components are combined with a critical path analysis of several RRR procedures. The report identifies potential solutions to some weather-related problems, and make recommendations for further study.
