PAVEMENT RESPONSE TO AIRCRAFT DYNAMIC LOADS. VOLUME III: COMPENDIUM

Instrumented aircraft were used to apply static and dynamic loads to instrumented pavement structures (both flexible and rigid) at the National Aviation Facilities Experimental Center (NAFEX), Atlantic City, N. J. Volume I of this report describes the resting program and instrumentation systems. Volume II with Appendixes A and B presents the reduction and analysis of data and the test results. This volume contains a compendium of the entire study. Measurements of displacement, velocity, pressure, and temperature were made in the two pavement structures. Two phases of material behavior, elastic inelastic, in both flexible and rigid pavement structures were identified. Each phase had to be treated independently for a full analysis of the static and dynamic load test results. The tests at NAFEC showed that no basic aircraft ground operating mode induced pavement responses (elastic plus inelastic) greater than those occurring for static load conditions. However, extrapolations of the test results indicate that for stiff pavement structures (such as the rigid pavement, and the flexible pavement during cold weather) unusual conditions (pavement conditions rougher than those during testing at NAFEC) of dynamic loading could cause responses larger than what would occur under static loading. This behavior is possible because of the inelastic behavior being of low magnitude for stiff pavements. The test results also indicate that a reduction in the thickness of pavement structures could be allowed in the interior of runways except at exits where aircraft side thrust is high.
