Cold In-Place Recycling (CIR) for Bituminous Over Concrete (BOC)
| 项目名称： | Cold In-Place Recycling (CIR) for Bituminous Over Concrete (BOC) |
| 摘要： | Cold in-place recycling (CIR) has been used for about 20 years in Minnesota, but only on hot mix asphalt (HMA) over gravel roads. Iowa has reported success using CIR on Bituminous over concrete (BOC) with less reflective cracking and less severe reflective cracking. The purpose of this project is to validate the Iowa practice. Along with the potential of a better service life, the cost of CIR is much less than new HMA, therefore a 20-30% price reduction may be realized on a project basis. This project would investigate HMA thicknesses, design and build a CIR with HMA on the top, then follow up each year measuring surface rating and ride each year for several years. Two new control sections should also be built and compared to the CIR section: a section with removing all the HMA and placing new HMA, and a M/OL section. The overall goal is to assess whether CIR works well over concrete. |
