Determining Bond Strength of Micro-surfacing Mixes - Phase 2
| 项目名称： | Determining Bond Strength of Micro-surfacing Mixes - Phase 2 |
| 摘要： | Micro-surfacing has been widely used by several transportation agencies including the Ohio Department of Transportation (ODOT) as a preventive maintenance treatment in order to extend the service life of the pavement. ODOT does not currently have a standard test method to measure the interface bond strength for asphaltic materials. The goal of this research is to evaluate the current practice as well as new equipment and application rates for tack coat to improve the service life and performance of pavement treated with micro-surfacing, resulting in significant cost savings due to the reduced need to repair these pavements. This research will be conducted in two phases. Phase 1 of this research developed recommendations for evaluating and improving the current practice for using tack coat in micro-surfacing applications. Phase 2 of this project will conduct lab and field tests to determine the bond strength between micro-surfacing mixes and existing asphalt surfaces with and without tack coat; evaluate and improve the current practice for using tack coat in micro-surfacing applications, and develop a required minimum bond strength in order to achieve satisfactory performance. |
