MEMBRANES FOR PAVEMENT/SHOULDER JOINTS
Shoulder drop-off on overlaid rigid pavements with asphalt concrete shoulders beneath the overlay is believed to be caused by water infiltration through the reflective crack over the old longitudinal shoulder joint. The study reported here was initiated to determine the effectiveness of 1) geotextile membranes placed over this longitudinal pavement/shoulder joint before overlaying, or 2) a saw-and-seal joint in the overlay over that joint, in reducing such water infiltration and thus preventing or minimizing the shoulder drop-off. Drop-offs are considered safe for all drivers when less than 37 mm, and safe for most drivers from 37 to 51 mm. In this study, all drop-off readings were 7 mm or less, with most being 4 mm or less. This shows that to date the test sections, although differing statistically from the control sections, are functionally the same.
