CORRELATION BETWEEN THE DYNAMIC (FWD) AND TRADITIONAL DEFLECTION MEASUREMENT METHODS

Deflection measurements in Hungary are carried out regularly using Benkelman beams for 40 years and Lacroix deflectographs for 20 years. The strengthening and the design of pavement structures are based on the deflection values, and the bearing capacity is one of the characteristic properties of the behaviour of road structures. Since 1991, measurements are carried out by KUAB falling weight deflectometer. The connection between the dynamic deflection and quasi static deflection, as the evaluation of the bearing capacity of the road network was based on the deflection measurements and the data are stored in the databank, had to be determined. Every databank stored deflection value refers the deflection determined by hand operated Benkelman beams at 20 degrees celsius asphalt temperature. In this report the first results of this work are presented.
