Popis:	This paper presents the experimental results of using a non-invasive time domain reflectometry (TDR) sensor to image and parameterize the moisture content of basecourse materials used in road construction. Imaging, resulting from the amplitude losses of a pulsed signal travelling down TDR transmission lines, is found to produce excellent information on the relative changes in basecourse moisture content to a spatial resolution $\sim 0.25$ % in volumetric moisture content is achieved when model coefficients are separately fitted for each of the two basecourse aggregate types tested.
