LaCroix deflectograph

The deflectograph is a two-axle truck carrying a beam assembly and an associated recording system between its axles. Deflection measurements are based on the same principle as in Benkelman beam measurements. The deflectograph provides a more rapid method of measuring pavement deflection than the Benkelman beam since setting arrangements are much faster. [Pg.767]

The processing of the data measurements with the necessary (temperature) corrections is performed by the PC software and the result is expressed as average deflection per point of measurement. [Pg.768]

Further information regarding the measurement collection process with the TRL UK Deflectograph is provided in Norman et al. (1973), Highways Agency (2008b) and WDM Limited. [Pg.768]

The back-calculation module used to compute layers elastic modulus requires data obtained from a Benkelman beam, a Lacroix deflectograph, or a FWD. [Pg.575]
