Abstract (en)
Context: Pavement condition data are a fundamental component of pavement management systems (PMS) and play a critical role in structural evaluation. The quality of these data directly influences decision-making processes at the network, project, or research level particularly regarding the pavement project life cycle.
Method: This study aimed to assess 18 techniques for evaluating the structure of flexible pavements, utilizing both non-destructive (NDT) and destructive (DT) testing. Following a comprehensive review of the consulted techniques, proprietary models were developed and implemented across multiple projects to structurally evaluate in-service pavements. Statistical analysis was employed to determine the relationships between parameters, distinguishing between those based on empirical and mechanistic approaches.
Results: The application of evaluation techniques revealed that parameters such as radial strain (εrca), vertical strain (εzsr), and the structural number exhibit a strong correlation when categorized within the same approach. Conversely, their correlation is moderately strong when differing approaches are used. Additionally, models relying solely on deflection basin data demonstrated high correlation with rigorous methods that incorporate thickness data.
Conclusions: These findings underscore the practical value of the developed models in pavement management at the network level, offering cost-effective solutions that enhance the detection of structural deficiencies and inform maintenance and rehabilitation strategies.

Contexto: Los datos sobre el estado del pavimento son un componente fundamental de los sistemas de gestión (SGP) y desempeñan un papel importante en la evaluación estructural. Dependiendo de la calidad de la información, estos datos son valiosos para la toma de decisiones a nivel de red, de proyecto o de investigación en relación con la gestión del ciclo de vida del pavimento.
Método: El objetivo de este estudio fue evaluar 18 técnicas de evaluación estructural de pavimentos flexibles basadas en ensayos no destructivos (END) y destructivos (DT). Después de una revisión integral de las técnicas consultadas, se desarrollaron modelos propios que fueron implementados en múltiples proyectos para la evaluación estructural de pavimentos en servicio. Se empleó el análisis estadístico para determinar las relaciones entre parámetros, distinguiendo entre aquellos que se basan en enfoques empíricos y mecanísticos.
Resultados: La aplicación de las técnicas de evaluación reveló que parámetros como la deformación radial (εrca), la deformación vertical (εzsr) y el número estructural presentan una fuerte correlación cuando pertenecen al mismo enfoque. Por otro lado, su correlación es moderadamente fuerte si el enfoque difiere. Además, los modelos que se basan únicamente en datos de cuencas de deflexión se correlacionan muy bien con métodos rigurosos que también requieren datos de espesores.
Conclusiones: Los resultados resaltan el valor práctico de los modelos desarrollados para la gestión de pavimentos a nivel de red, proporcionando una solución eficiente en costos que facilita la detección de deficiencias estructurales y mejora las estrategias de mantenimiento y rehabilitación.
