USE AND IMPORTANCE OF DEFLECTION MEASUREMENTS MADE ON ROADS IN FRENCH SPEAKING AFRICA AND IN MADAGASCAR

UTILISATION ET INTERET DES MESURES DE DEFLEXION SUR CHAUSSEES EN AFRIQUE FRANCOPHONE ET A MADAGASCAR

The author recalls the extensive use of deflection measurements as a non-destructive means of testing pavements for the design of new pavements and control of application during construction. The measurements give highly representative results of the mechanical behaviour of the pavements. The technique is widely utilized in french speaking Africa and in madagascar. Details are given of the evolution of the technique and of some results obtained on flexible pavements. Precautions to take while carrying out measurements are mentioned. /TRRL/
