This study presents the results of an investigation of emulsion residue recovered in 2012 from a chip seal placed in Death Valley, California, in 2008. This circular paper reports techniques used successfully to collect, extract, and measure the physicochemical properties of the emulsion residue as well as potential difficulties to be considered in each step. The results of the investigation are compared to the laboratory-recovered emulsion residue on the same chip seal project reported by King and Johnston (2012).
