THE USE OF DEFLEXION MEASUREMENTS FOR THE STRUCTURAL DESIGN AND SUPERVISION OF PAVEMENTS
Measurements of deflection have been used for a long time in studying the behavior of pavements; and many instruments and procedures have been developed in different countries. The undeniable popularity of these measurements is due to the fact they are relatively easy to make. But the crude application of correlations obtained empirically may be dangerous, in view of the number of factors which can contribute to the deterioration and destruction of a pavement and the evergrowing variety of structures built. This article gives some of the indications concerning the theoretical and experimental justifications applicable to measurements of deflection and related measurements, and to point out that the interpretation of such measurements, and the limits of their utilization.
