The present technical guidance aims at providing a methodology for pavement testing using HWD. It gathers recommendations relative to operational survey and data analysis, based on an advanced dynamic modeling.
The operational recommendations include all information about platform survey and test carrying out. In particular, the requirements to meet before pavement testing and data analysis are respectively described. They consist in requirements relative to the device, in necessary complementary information about the pavement and in the traffic data.
The recommendations relative to the data analysis gathers the description of the mechanical modeling and its parameters, as well as the one of the associated backcalculation process developed.
All parts of the guide have been validated, numerically or using in-situ measurements. Last part of the document is dedicated to illustrations using real case studies.
