GPR aplicado na investigação de fatores que levaram ao colapso parte de um pavimento asfáltico.


This paper presents the results of a research developed with Ground Penetrating Radar (GPR) referring to the investigation of possible factors that caused the collapse of the central part of the pavement of an avenue due to the emergence of a hole. The geophysical survey with Ground Penetrating Radar (GPR) aimed to identify the interfaces between the different constituent layers of the pavement, determine their thicknesses, verify the technological conditions of the materials constituents of these layers, investigate the presence of voids and groundwater pipelines. The use of Ground Penetrating Radar (GPR) proved to be quite effective, allowing to identify the thicknesses of the layers that structure the pavement, the pipes present in the area and a region of alteration that was associated with the possible cause of the collapse of the avenue pavement.
