Kansas Pavement Preservation Initiative
| 项目名称： | Kansas Pavement Preservation Initiative |
| 摘要： | Like many other states, dwindling budgets for pavement preservation programs are forcing the Kansas Department of Transportation (KDOT) to look at pavement preservation techniques. Pavement preservation has been a hallmark of the pavement management system - NOS. The KDOT pavement preservation program actions include route and crack seal, chip seal, 1- to 4-inch overlay, 1- to 4-inch inlay, heater scarification, cold in-place recycle (4-inch), Nova chip, modified slurry seal, cold milling, PCC patching, PCC dowel bar retrofit, PCC replacement, joint repair, diamond grinding, and combinations of the above actions. While the timing of these actions are picked up by the KDOT's sophisticated NOS systems, the selection of pavement preservation projects requires engineering judgment, informed with the best available data. This practice by the highly experienced engineers and satisfactory, steady funding of the KDOT pavement preservation program have led to a system that is among the best in the nation. However, with the impending expiration of the Comprehensive Transportation Program (CTP), the funding of the pavement preservation program appears to be less certain. In order to secure future funding, the benefits of such a program need to be quantified. There are many pavement maintenance and preservations technologies, materials, and systems that had been used by KDOT in its pavement preservation program. For the most part, the methods were selected based on historical experiences or based on the manufacturer's recommendations for the proprietary ones. Thus there are large knowledge gaps in terms of effectiveness, durability, and other important factors. For this reason, the life cycle costs of these treatments cannot be truly calculated. That is why, a carefully planned and coordinated education, research, innovation, and implementation plan for pavement preservation in Kansas is urgently needed. |
