STRUCTURAL MODEL FOR CONCRETE BLOCK PAVEMENT

A structural model for the calculation of stress, strain, and deflection in a concrete block pavement is described. This model is based on the ICES STRUDL computer program that was recently extended by the introduction of a so-called RIGID BODY element. It is shown that by means of this model excellent agreement between measured and calculated deflection profiles is obtained. Furthermore, time functions were derived from the observation of 20 concrete block pavements in service. These functions show the increase of the subgrade modulus, the stiffness of the joints and the bedding layer, and the decrease in the deflection with respect to the number of equivalent 100-kN single axles. By means of ICES STRUDL and the developed time functions tentative design charts are developed in which the number of years until a given rut depth is reached is related to the initial subgrade modulus and the average daily equivalent 100-kN single axle loads. Although concrete block pavements are common in western Europe (about one-third of the paved area in the Netherlands consists of such pavements), this pavement type is not well known in the United States. Therefore a general description of the most characteristic features of concrete block pavements is given.
