Abstract

The authors have modelled some of the effects caused by the introduction of a camouflet in the subgrade beneath a cement concrete runway and a polystyrene subsurface layer. The results show that the polystyrene increases runway deflection, with the increase being less over the camouflet than over the undisturbed subgrade. Where there were stress concentrations in the polystyrene, they occurred directly over the interface between the disturbed and undisturbed subgrade. The load cases with the stress concentrations in the polystyrene were the same load cases that had the greatest deflections. A means of identifying the location of a camouflet by obtaining deflection and settlement measurements as heavy loads traverse the length the undamaged and the damaged runway is described.
