New parameters to correct relative moisture effect on central measured deflection when comparing several data auscultation.

When we are trying to evaluate the evolution of the bearing capability of the recycled pavement layers by means of the measured central deflection we have to take into account the moisture effect. The measured deflection depends on the granular layers moisture, so if we want to compare deflections with several moisture conditions it‘s a must to correct them as they were measured with the highest moisture conditions.

With the aim of estimating the granular moisture conditions while measuring, a new parameter had been developed taking into account the farthest deflection from the load plate. Correcting the moisture effect with this parameter a more accurate structural analysis can be done.
