Binder Properties<br />

Binder Extraction<br />

• Toluene/95% Ethanol<br />

Binder Rheology<br />

• DSR; G*, phase angle, MSCR<br />

• BBR: S, “m-value”, physical hardening<br />

Binder Chemistry<br />

• Infrared spectroscopy (IR) - carbonyl<br />

• Nuclear magnetic resonance (NMR) - branching<br />

• Differential scanning calorimetry (DSC)– wax<br />

• Elemental analysis – chemical fingerprint<br />

• HPLC - EH&S issues<br />

• Rostler, Corbett, asphaltenes<br />

Test results: characterizations did not relate much to performance<br />

The Western Research Institute ran several chemical analyses on products used for<br />

the initial trials. From the field trial results, physical performance testing of mix<br />

properties appears to give more reliable information regarding rejuvenator<br />

effectiveness than the chemical or physical testing of extracted binders.<br />
