| Objectives: | This project will result in extended pavement surface life and thus reduced roadway rehabilitation and maintenance costs. Guidelines for sealant selection are being proposed because the durability of crack sealants used on the North American roadways is often shorter than expected, even though crack sealing is the most common method of preventative maintenance. |
| Comments: | A technical panel has considered sealant homogeneity/segregation and deemed it a construction (not materials) issue and therefore beyond the scope of the current study. A proposed accelerated sealant aging method is being considered for further development and will likely be validated through a comparison of sealants aged in the laboratory against six sealants weathered in the field for up to 9 years. Finally, bending beam rheometry, direct tensile testing, and creep-recovery are being evaluated (for low temperature testing) to determine if any of these methods are sufficiently developed for inclusion in the performance-based specification.
