Fundamentos y ejemplos de aplicación del ensayo no destructivo de reflexión electromagnética mediante georradar en pavimentos asfálticos

Abstract

La prospección mediante Ground-Penetrating Radar (GPR) aplicada al estudio del pavimento de una carretera es un método no destructivo de análisis que, poco a poco, se ha ido implantando para la auscultación de carreteras. Este método, basado en la detección de discontinuidades electromagnéticas en el interior de un medio, permite registrar el tiempo de propagación de una señal electromagnética desde que se emite hasta que se recibe tras su reflexión en la discontinuidad. El registro de tiempos permite determinar espesores de las capas de un pavimento cuando se conoce la velocidad de propagación.También permite conocer algunas de sus condiciones físicas, generalmente contenido en huecos y grado de saturación. Además, los cambios de amplitud de la señal también permiten analizar características como el despegue entre capas. El conocimiento de estos factoreses fundamental para diseñar refuerzos de un pavimento asfáltico mediante métodos analíticos. En este estudio se muestran algunos ejemplos de aplicación con resultados obtenidos en vías de acceso a la ciudad de Barcelona.
