Abstract
The excess pressures anticipated underneath the asphalt facing of a number of sea dykes were determined with the aid of plate-shaped electrical conductors and alternating current. As these excess pressures are influenced by factors varying from place to place in the prototype, a series of tests were carried out in which one or more of these factors were varied. With the help of some examples the following subjects will be dealt with: - the influence of permeability and its inhomogenity; - the influence of various forms of drainage in the toes of the dykes; - the consequences of air being imprisoned between the facing and the surface of the ground water.
