- Resumen
The Ground Penetrating Radar test applied to road engineering is overall used to determine the geometric characteristics of the pavement structure by analyzing the wave in the time domain. On many cases, it is often used to assess the stiffness modulus of structural layers analysis using the method known as retro-calculation, as it is indicated by the main guide mechanistic-empirical design of asphaltic pavements.However, the geophysic principles on which the GPR test is based, allows obtaining the data associated with the pavement and its structural condition. It is possible thanks to the interpretation of the response of a material against an electromagnetic wave. Physical variables associated with the wave response can be related with structural pathologies, for example, the presence of moisture or low cohesion level between the pavement layers.This thesis discusses the possibilities of the GPR test in order to allow the design of future status indicators, associated with the structural deterioration of a pavement. This can be possible by analyzing the radar wave in its time and frequency dimensions. Status indicators based on the GPR response signal allows a significantly reduction of the number of destructive tests in a pavement, such as coring, or other non-destructive but expensive and high logistical complexity tests, such as deflection tests.
