Abstract

Full-scale test sections were constructed and trafficked at the U.S. Army Engineer Research and Development Center (ERDC) to provide performance data comparing the effectiveness of multi-axial geogrid stabilized flexible pavement sections to an unstabilized flexible pavement section.  Two test sections containing differing multi-axial geogrids were constructed and trafficked under shelter in ERDC's Hanger 2 Pavement Test Facility.  The test sections were subjected to accelerated traffic loading using a dual-tandem axle configuration simulating typical highway loadings.  Permanent surface deformation, rutting, pavement stiffness, and instrumentation response data were collected at designated traffic intervals.  The results of the study indicate that the geogrid stabilized sections improved the performance of the pavement section when compared to the unstabilized section.
多轴土工格栅稳定柔性路面性能研究
在美国陆军工程研究与发展中心(ERDC)进行了全尺寸测试,以提供性能数据,比较多轴土工格栅稳定柔性路面路段与非稳定柔性路面路段的有效性。在ERDC的Hanger 2路面测试设施中,建造了两个包含不同多轴土工格栅的测试段,并在掩体下进行了测试。试验路段采用双串联式车轴结构,模拟典型公路荷载,承受加速交通荷载。永久地表变形、车辙、路面刚度和仪器响应数据在指定的交通间隔收集。研究结果表明,土工格栅稳定段与非稳定段相比,改善了路面段的性能。
