Moisture Content and In-Place Density of Cold Recycle Treatments
| 项目名称： | Moisture Content and In-Place Density of Cold Recycle Treatments |
| 摘要： | This study proposes investigating the feasibly of monitoring moisture content and density of an emulsified asphalt mixture during curing. The dielectric properties and resilient modulus of the CIR will be evaluated using GPR and the light weight deflectometer (LWD), if available. The relationship between the dielectric constant and the moisture content of the emulsified asphalt mixture will be evaluated, and the moisture content will be predicted or indicated based on GPR measurements. A moisture content prediction or an indicator model will be proposed to assist in the decision-making of traffic-opening time. In addition, it is proposed to modify the ALL model for in situ density prediction of CIR-treated AC mixtures based on the results from this project. This suggests that the effect of internal moisture content will be considered. |
