Abstract
On behalf of a Forschungsgesellschaft für Strassen und Verkehrwesen (FGSV) working group at Cologne, deflection measurements were carried out with nine different devices on sixteen different pavements (40 points on each pavement). The statistically presented results were expressed as deflection values per unit load. Correlation equations were then developed. Using these equations, an evaluation was made of the influence of the different configurations and load frequency on the measured deflections.
