DESIGN OF NEW AND TESTING OF EXISTING PAVEMENT STRUCTURES

ONTWERP VAN NIEUWE EN ONDERZOEK VAN BESTAANDE WEGCONSTRUCTIES

This paper is based on a lecture given at Delft University of Technology. The design of new pavement structures with the aid of the Shell design procedure is outlined. The input data have reference to traffic load, climate and properties of the subsoil, roadbase and flexible pavement materials. In the design model the several layers are characterized by the modulus of elasticity and Poisson's ratio. The layers are assumed to be linear elastic, homogeneous, isotropic and infinite in the horizontal plane. The main design criteria are the maximum vertical strain at the formation surface and the horizontal strain at the bottom of the surfacing. The effects of the average temperature and the mixture quality upon the designed thickness of the various layers are discussed. Evaluation methods for testing existing pavements are deflection and wave velocity measurements. Various measuring instruments are described. The calculation of layer thicknesses with the aid of shell design charts is discussed. An improved design procedure is being prepared. /TRRL/
