MDOT Specific Design Procedure for Chip Seals
| 项目名称： | MDOT Specific Design Procedure for Chip Seals |
| 摘要： | Historically, the Mississippi Department of Transportation has used chip seals as a preventative maintenance treatment on low traffic rural routes. Developing a methodology to design and evaluate the performance of the design is important to produce a cost effective and long lasting product. Currently, the Department sets target application rates for the binder and aggregate based on general material properties. In addition, the current specifications do not make allowance for the condition of the roadway at the time of placement of the chip seal. Basic chip seal design procedures are needed to establish the binder and aggregate application rates considering the actual component materials, environmental factors, traffic, and existing roadway surface condition. As a part of the design procedure, a test method or methods are needed to evaluate the chip seal design to help ensure the durability of the chip seal and help establish construction criteria for rolling, sweeping, and opening to traffic. |
