![]() One of the unique features of APSDS is that it takes rational account of aircraft wander. Wander is the measure of how successive aircraft deviate from runway or taxiway centre lines. Increased wander reduces pavement damage by different amounts that depend on pavement thickness. Concrete pavement design software update#Ĭomes with a Standard Aircraft Library – that you can update automatically by installing newer versions of APSDS.Pavement and loading databases save re-keying information.you can export results to other application packages such as word processor or spreadsheet.results in tabular form and report quality graphs.Typical runs take a few seconds on Pentium PCs.The user-friendly interface runs under Microsoft Windows.Incorporating wander can lead to significant savings in construction costs. ![]() special loadings such as braking included.no inaccurate short-cuts such as “equivalent” single wheels.analysis explicitly uses specified spectrum.wander statistics specified by the standard deviation.no limit on the number of aircraft types or loading conditions.Sample plot of the lateral distribution of cumulative damage predicted by APSDS You can export results in tabular form and report-quality graphs. Reservoir Method for calculating damage due to complex loadingsĪPSDS 5.0 handles complex loadings by the ‘reservoir’ method, as used in bridge design. The ‘reservoir’ method consistently computes the damage from overlapping strain pulses due to multi-axle landing gears. With our new calibration (details in this paper ), APSDS 5.0 pavement designs are thinner than given by the FAA design software, FAARFIELD.Ĭlick here for more details and sample designs for A380-800, B747-400 and B777-300 aircraft.Ĭalibrated to latest full-scale test results This feature will optimise up to three layers. The Cost Analysis feature lets you fine-tune layer thicknesses to lower construction and maintenance costs.įor example, for this pavement structure, you can easily find the Base and Subbase thicknesses that will minimise total cost: Cost OptimisationĪ Parametric Analysis feature can loop through a range of thicknesses for one or two layers while simultaneously designing the thickness of another layer.
