PAVEMENT DEFLECTION FILE FOR THE ROAD NETWORK IN FRANCE

LE FICHIER DES DEFLEXIONS DES CHAUSSEES DU RESEAU ROUTIER FRANCAIS

THE DEFLECTION FILE, BASED ON MEASUREMENTS MADE WITH THE LACROIX DEFLECTOGRAPH, CONTAINS ALL THE RESULTS OBTAINED IN THE REGIONAL LABORATORIES SINCE 1969, THAT IS TO SAY THE EQUIVALENT OF 80000 KILOMETRES. THERE EXIST TWO TYPES OF FILE: THE HISTORY-MUSEUM FILE AND THE OPERATIONAL FILE. THE FORMER CONTAINS ON MAGNETIC TAPE ALL MEASUREMENT FIGURES PER YEAR AND IS USED ONLY IN VERY SPECIAL CASES. THE LATTER, ARRANGED SEQUENTIALLY AND INDEXED ON MAGNETIC FILES, IS USED FOR DIRECT SEARCHES AND THE PERIODICAL EDITION OF THE RESULTS. TO ORGANIZE AND CONTROL SUCH A FILE, THE PROCESSING PROCEDURES HAD TO BE AUTOMATED, A STRICT METHOD OF DETECTING AND CORRECTING ERRORS HAD TO BE DEFINED, AND THE PROBLEMS OF CLASSIFYING DATA, UPDATING AND RELATING TO OTHER FILES HAD TO BE OVERCOME. THE FILE CAN ALREADY BE USED FOR: MAKING STATISTICAL STUDIES FOR CENTRAL AND REGIONAL SERVICES, GIVING INFORMATION ON CHANGES IN THE NETWORK AND CERTAIN TYPES OF STRUCTURE, (PROGRAMMING STRENGTHENING OR MAINTENANCE OPERATIONS), CREATING GENERAL LAWS FOR SETTING UP RESEARCH OR STUDIES.
