crushed stone compositions is photogrammetric surveying. To create the surface of the crushed stone barrier, the barrier was photographed from all sides using a hand-held 3D laser scanner, AlphaGEO SLAM R100. SLAM R100 is a portable real-time 3D reconstruction device developed by AlphaGEO, which integrates a LiDAR module, a
Crushed stone has higher resistivity than surface soil, and so the potentially dangerous ground current remains confined to surface soil and isolated from a worker's or passerby's feet. There will be very little current in the crushed rock; hence, surface voltage (step and touch potentials) will be negligible.
