Recycled Unbound Pavement Materials
| 项目名称： | Recycled Unbound Pavement Materials |
| 摘要： | This project is expected to consist of the following activities: Work Plan: The work plan for this pooled fund study will be developed by the participating organizations. This will include selecting recycled materials to construct the base layer for 3 cells at MnROAD. Possibilities include: (1) 100% crushed concrete; (2) crushed concrete blended with virgin aggregate; and (3) RAP blended with virgin aggregate The pavement surface must also be carefully selected for these sections. Ideally, the same pavement will cover all three cells so as to minimize variables in the experiment. Instrumentation Design: Thermocouples, TDRs (moisture), strain gages, etc. General Testing & Monitoring: Monitor the pavement performance over time on each test section. Monitoring activities will include FWD tests, rutting measurements, distress surveys, ride measurements, and analysis of pavement sensor data. Special Testing & Monitoring: Unsaturated soil properties, resilient modulus, seasonal variation of material properties, etc. Design Guide Modeling & Validation: The material properties for recycled unbound layers will be modeled in the new mechanistic-empirical design procedure. Pooled Fund Travel: Money for each state to travel to discuss the progress of the study. Data Analysis & Reports: Work done under a research contract will develop interim and final reports that document the findings of this study. |
