Abstract:Electronic resistance tomography (ERT) was used to follow the infiltration of water into a pavement section at the UC Berkeley Richmond Field Station. A volume of pavement 1 m square and 1.29 m in depth was sampled by an ERT array consisting of electrodes in 9 drilled holes plus 8 surface electrodes. The data were collected using a computer-controlled data aquisition system capable of collecting a full data set in under 1 hour, allowing for nearly real-time sampling of the infiltration.
