Testing by UTEP<br />
The results from the Spectral Wave Analysis with Portable Seismic Pavement<br />
Analyzer (PSPA) indicated that the change in modulus between depths of 1 in.<br />
(which is the upper resolution of the device) to 4 in. was either small or insignificant.<br />
The rheological tests on the cores run at WRI and MTE indicate that 1 in. is too<br />
deep to capture the strongest aging effects. Furthermore, the fog seal emulsions<br />
rarely infiltrate into the pavement more than 0.5 in. Therefore, use of this device<br />
was abandoned early in the project.<br />
