Lightweight Deflectometer (LWD) for Acceptance of Unbound Materials
| 项目名称： | Lightweight Deflectometer (LWD) for Acceptance of Unbound Materials |
| 摘要： | There is a desire by Missouri Department of Transportation (MoDOT) to move away from the Nuclear Density Gage (NDG) as the primary device for evaluating compacted materials. MoDOT recently participated in a pooled fund project with Maryland DOT and the University of Maryland that studied this issue and produced draft standards for use of the Lightweight Deflectometer (LWD). This project will develop a procedure and standards for using a LWD for acceptance of unbound materials. It is intended to build on the findings from the pooled fund study to tailor the results for Missouri; not duplicate the previous work. |
