Abstract
The ground-penetrating radar (GPR) transmits an electromagnetic wave, and it is a non-destructive test that can be used in geotechnical applications. One of the main benefits of this device is to explore buried underground objects. The study is proposed to find asphalt thickness and compare it with the core test (destructive test) and their error rate. The survey was also intended to detect buried services utilities (pipes, electrical cables, manholes, groundwater level). The current study focuses on finding the device’s error rate using an antenna with medium frequencies of 450 MHz in exploring a network of buried pipes, manholes, and electrical cables and comparing them with the actual execution to find the percentage error of the device. The GPR has relatively high accuracy with an error rate for buried utilities and pavement thickness compared with the actual execution is between 4.3% and 10%.
