Abstract

Abstract

In order to study the subgrade deformation beneath the sandwich panel which was subjected to repeated aircraft load, four aluminum honeycomb sandwich panels with different thickness and strength were trafficked and the soil plastic deformation was surveyed. The performance data were analyzed and presented graphically to build a simple predictive model including traffic times and base strength. The simplify model was revised and compared with conventional models. The results show that the soil deformation is in proportion to the logarithm of times, and inversely proportional to base strength. Fatigue cracking is the main failure reason of pavement structures. The maximum traffic times calculated by three different design equations are 4.071013, 288, and 487 990 respectively when pavement D is installed over the soil with 70MPa strength.
