Evaluating Recycling Efficiency of Asphalt Plant
| 项目名称： | Evaluating Recycling Efficiency of Asphalt Plant |
| 摘要： | This project is a continuing joint effort of TDOT and UT to determine the percentage of the aged asphalt binder in recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) that can be blended into virgin binder and reused in recycled asphalt mixtures. In a previous study, UT researchers have developed a laboratory procedure to determine the blending efficiency of RAP and RAS mixtures. They also validated the proposed method with laboratory-prepared asphalt mixtures containing RAP and/or RAS. With the increased use of RAP and RAS into asphalt mixtures, the effects of RAP and RAS on asphalt pavements have become increasingly important. If the aged binder in RAP and RAS cannot be 100% blended into virgin binder and reused in the recycled asphalt mixtures, the performance of asphalt pavements will be suffered and its service life will be shortened. Therefore, the recycling efficiency issue has to be solved so that the benefits of using RAP/RAS can be realized and durable asphalt pavements can be ensured. This research project will build upon the previous TDOT-sponsored RAP/RAS studies and determine the blending efficiency of different asphalt mixing technologies used by the asphalt plants in Tennessee and evaluate its impact on the performance of the resulting asphalt mixtures |
