| 摘要： | Under the Strategic Highway Research Program Project H-106, a field experiment is being conducted to evaluate the performance of various materials and procedures used in treating cracks in pavements surfaced with asphalt concrete. Four transverse crack seal sites and one longitudinal crack fill site were installed in the United States and Canada. At each site, several experimental 'treatments' were applied by participating state maintenance departments. Each treatment consists of a material, a placement configuration, and a crack preparation procedure. Evaluation results show 100% failure of a proprietary emulsion sealant placed at one site, and 40% average failure of a fiberized asphalt sealant installed at all 4 sites. The remaining experimental sealant materials have shown less than 10% overall failure, and all experimental crack-filler materials have shown less 2% overall failure. Also, the simple band-aid sealant configuration has experienced between 4 and 20 times more failure than the reservoir-and-flush and the recessed band-aid sealant configurations. |
