摘要：	Pavement markings can contribute to the deterioration of surface courses and in some cases it was found that the markings are the main source of distress. The reasons for such damage are outside the scope of this work but it was speculated that water vapor trapped under the pavement marking can lead to moisture damage and raveling in this high voids mixtures. A change in gradation which was implemented in 2008 should help with this condition by increasing the binder content and reducing the voids. Furthermore, as of 2008, UDOT has discontinued the use of OGSC. Other surface treatments (slurry seals, SMAs, etc.) might prove to be more durable and less susceptible to the type of distresses observed as part of this work. However, careful selection of the right treatment for the right condition along with proper controls during production, placement, and compaction of surface mixtures is still needed to obtain longer lasting pavement surfaces. / Title Note: Final rept. / Supplementary Notes: Sponsored by Utah Dept. of Transportation, Salt Lake City. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
