Evaluating Roadway Subsurface Drainage Practices
| 项目名称： | Evaluating Roadway Subsurface Drainage Practices |
| 摘要： | The purpose of this project is to develop a means for assessing the drainability of subgrade soils in Tennessee and conduct a comprehensive performance review of them under different weather conditions (e.g., high-intensity storms, sequences of storm events, winter weather requiring salt application). The scope of this work includes a combination of geospatial mapping, analytical methods, and controlled lab experiments. We will identify critical areas in the three regions Tennessee (east, central, and west) that are prone to poor drainage using satellite-based, remote sensing and GIS information. The performance of current and alternative drainage designs will be assessed using a simple drainage calculator. The performance of the proposed alternative designs will also be determined using complementary laboratory analyses that consider, for the first time, all three mechanisms of water entering the sublayers, namely, penetration through pavement joints and cracks, lateral seepage from ditches, and intrusion of rising groundwater. |
