State-of-the-Art Rapid Non-Destructive Pavement Assessment: Ground Penetrating Radar (GPR) in Monostatic Survey Mode

摘要

A feasibility study on investigating state-of-the-art non destructive pavement assessment using ground penetrating radar (GPR) has been conducted. We have found substantial advance in GPR antenna design over the last several years. The ultimate goal of all new designs is achieving higher transmission efficiency. The interpretation software mainly use the artificial neural network. In terms of survey method, in addition to the commonly used monostatic transmitter-receiver pairs, multiple transmitter-receiver pairs start to merge in the pavement assessment practice.
