USE OF PAVEMENT EVALUATION DATA FOR THE STUDY OF ROAD RECONSTRUCTION REQUIREMENTS IN FRANCE

The method of testing used on French roads, before work is done on them, is in four stages: (1) the gathering of information of a continuous character and the plotting of this information on the road diagram. (2) the analysis of this information and division of the road into uniform zones. (3) the selection and investigation of reference sections. (4) analysis of the information gathered on the reference sections. While the procedure is similar for semi-rigid pavements and flexible pavements, the third stage--limited in the case of the latter--is essential in the case of pavements with stabilized bases and subbases, since it is the key to an understanding of the structure and origin of deteriorations. In this article, the deflection measurement is regarded as a criterion of uniformity for the division into zones; since it is still an indicator of poor quality, it must be supplemented by a thorough visual analysis in the case of stabilized structures. For pavements of this type, the author presents two additional tests (the lightweight vibrator and the measurement of product rd), which, thanks to the experience acquired in France, serve to obtain information about fragile zones for the establishment of a diagnosis. The simultaneous examination of these two test results is facilitated by a "reference chart", which is part of a summary document known as the "analysis sheet". (Author/TRRL)
