Evaluation of Existing Pavements and Conçrete Overlay Design in the Netherlands

Paper by BEUVING STET from ISCR 6th 1990

Working Committee «Overlay in concrete» is founded to create a manual containing practical methods for designing and building concrete overlays for road and airport pavements for Dutch conditions. Results of the Working Committee activities are presented in this paper. A method to determine the bearing capacity of existing pavements is described. The evaluation procedure is based on Falling Weight Deflection measurements. Depending on the visual and structural condition of the existing pavement several types of overlay (design) are possible. Overlay design procedures as well as design charts are presented for a thick overlay on a PCC or asphalt pavement and a thin bond PCC overlay on a plain PCC pavement.
