| 摘要： | Over the course of the last 17 years, approximately 12 different studies have shown the potential for the use of geosynthetic materials (geogrids and geotextiles) as a reinforcement inclusion in the base course aggregate layer of flexible pavements. This research was undertaken to provide experimental data that could be used to further establish the mechanisms of geosynthetic-reinforcement that lead to enhanced pavement performance. Subsequent work will involve the use of this data in developing numerical models and design solutions for this application. Pavement test sections have been constructed in a laboratory-based pavement test facility. The facility consists of a large concrete box in which field-scale pavement layers can be constructed. The results have shown that the inclusion of a geosynthetic provides a reinforcement effect. |
