| Today, the new pavement management tools encourage preventive action, whereas more traditional approaches focus on acting on observed damage. An adequate initial evaluation is essential to properly manage pavement maintenance. In this regard, nondestructive tests such as deflection tests make it possible to obtain first-hand information without altering the condition of the pavement, and their use is becoming increasingly more common. This paper presents a study of the structural evaluation of rigid pavements based on measured deflections. Several aspects are identified which will make it possible to improve these procedures. A 62-kilometre stretch a motorway in Mexico has been used as a case study. A campaign of on-site measurements was carried out using a Falling Weight Deflectometer (FWD). The deflection values were used in several iterative methods with calculation programs and manual analytical methods, comparing the results obtained. The elastic moduli of the pavement layers were determined. These are the main parameters for calculating the remaining life of the structure, which facilitate decision-making around pavement management. The results obtained in this study emonstrate the usefulness of back-calculation methods for analysing the structural condition of rigid pavements as an initial stage in the development of pavement management systems. The conclusions validate the use of back-calculation programs in the structural analysis of rigid pavements, by comparing the results obtained with manual analytical methods. | |
