• Description:
  The main objective of this study was to evaluate the effectiveness of Glasgrid as a reflective crack reducing method. Two locations were selected for evaluation. The first location was on I-70, west of the Eisenhower Memorial Tunnel. At this location the section containing the Glasgrid was evaluated and compared to an equivalent section containing the material (Trevira Spunbond) and an untreated section. The second location was on U.S. 40, east of Hayden. On this project the Glasgrid was placed at two locations. At the first location the Glasgrid was placed over a railroad crossing which was no longer in use. The remainder of the Glasgrid was placed over the construction joint where the pavement was wider. Following the four year evaluation the pavement in the Glasgrid section has a significant more amount of cracking in the wheel paths than the Trevira and untreated sections. Most of the longitudinal cracking in the wheel path has deteriorated into alligator cracking. Neither of the other two sections are showing any signs of this type of distress. Cracking in the Glasgrid section is appearing at a much faster rate than cracking in the Trevira and untreated sections. As of the final evaluation the U.S. 40 east of Hayden location shows no evidence of reflective cracking at the construction joint. This includes both the untreated and treated areas. The Glasgrid over the railroad tracks did not prevent reflective cracking. The overlay and Glasgrid was removed and the railroad tracks were restored. Based on findings from this study, it is not recommended to use Glasgrid as a crack-reduction treatment without further data supporting its effectiveness.
