Feasibility of pervious concrete as engineered material arresting system for airport runway safety areas

چکیده
Abstract From the late 1960’s airport engineers developed special paving material for arresting aircraft gears in event of overrun as a partial extension runway end safety area. Such pavement surface material, inverting general concept, should be crushed over first pass gear wheels resulting to sink and being promptly arrested abrupt loss velocity, preferability avoiding lives injuries well with minimum risks airplane structural integrity. Herein is analyzed discussed possible application pervious concrete such task by simulating an actual situation (Congonhas airport) understanding effects on crushable layer, pointing out stresses, deflections required strengths material. Simulations regarded critical A 320-200 fire-fighters cars pavements. Analysis complied Federal Aviation Administration requirements non-standard structures simulation stresses trough finite element method medium-thickened plates. Compressive along flexural excessive besides predictable punching shear allowed conclude feasibility using low strength alternative engineered built system.

We present a mixed integer programming (MIP) model to solve the problems of (i) selecting an airport’s optimal sequence of runway configurations and (ii) determining the optimal balance of arrivals and departures to be served at any moment. These problems, the runway configuration management (RCM) problem and the arrival/departure runway balancing (ADRB) problem, respectively, are of critical i...
