AN ALTERNATIVE APPROACH TO BEARING CAPACITY: IMPULSE DYNAMIC INVESTIGATION

On flexible pavements, the bearing capacity, measured via the deflection under a known load, static or rolling, is a very useful parameter for evaluating structural condition. But this approach is not so well suited to modern pavements, those built in the last 25 years in industrialized countries. On these pavements, which may be semi-rigid, thick bituminous, or hybrid, the traffic-induced damage processes are not always comparable to those observed on flexible pavements. In addition to more or less fruitful efforts to adapt the deflection measurement to modern pavements, the Laboratoires des Ponts et Chaussees, in France, have developed original techniques such as ovalization and dynamic investigation. There have, as a result, been important developments in "impulse" dynamic investigation; these continue, and this article is an interim report on them.
