SPR-3807: Investigating the Need for HMA Drainage Layers
| 项目名称： | SPR-3807: Investigating the Need for HMA Drainage Layers |
| 摘要： | The objective of this project is to determine if flexible pavements without HMA drainage layers can perform as well, or better as flexible pavements containing them. Project deliverables include: updated hydraulic properties of current INDOT HMA materials; model of moisture migration in flexible pavements; results indicating if newer specifications better inhibit moisture migration; and a plan for long‐term monitoring of the instrumented pavement sites. |
