Non destructive evaluation and inverse methods
ByBernardo Caicedo
Pages 29

Several non destructive road structure evaluation methods have been developed over the last fifty years. The fundamental idea of these methods is to either apply a load to the road structure, or send an electromagnetic wave through the road structure, in order to measure the structure’s response. Usually, a static or a dynamic load similar to the load produced by a truck are applied and then used to measure the deflection basin. As a complement, the use of electromagnetic waves is useful for distinguishing the properties of each layer of a road’s structure.
