Emulsion residue properties<br />
Cores were taken at various intervals from some of the projects and sent to Dr.<br />
Mike Harnsberger of the Western Research Institute (WRI) for extraction for<br />
chemical and rheological testing. Before testing, the cores were cut into horizontal<br />
slices to determine the properties at varying depths in the pavement. Core samples<br />
were also sent to Gerald Reinke at Mathy Technology & Engineering Services, Inc.<br />
(MTE) for rheological testing on the mix slices, to Dr. Becky McDaniel and Ayesha<br />
Shah of the North Central Superpave Center for permeability testing, and to Dr.<br />
Mihai Marasteanu of the University of Minnesota for a newly developed Static<br />
Bending Test on rectangular specimens cut from field cores using the Bending<br />
Beam Rheometer (BBR). 2006 project emulsion samples were sent by the<br />
suppliers to Dr. Alan James of Akzo-Nobel <strong>Surface</strong> Chemistry LLC for surface<br />
tension and particle size testing.<br />
