Settlement and Void Mapping – Ashkelon Railway Crossing (Israel Railways)

For the project involving the installation of a 40-inch pipeline using the microtunneling method beneath the Ashkelon railway, a Ground Penetrating Radar (GPR) survey was conducted to document the subsurface conditions prior to the commencement of construction. The purpose of the survey was to establish a baseline for identifying settlements, voids, and changes in subsurface conditions resulting from the microtunneling operation. The data were processed and interpreted in accordance with ASTM D6432.
