建立了县乡公路路面使用性能预测模型。大多数县铺设的道路是几十年前建造的，没有遵循最低设计标准。最近，怀俄明州的工业/矿业活动增加，需要开发一个路面管理系统（PMS），用于当地铺设的道路。开发的PMS使用路面使用性能指数（PSI）作为路面性能参数。建议PSI模型的基础上，地方道路：国际平整度指数，路面状况指数（PCI）和车辙深度的柔性路面。来自怀俄明州的10名小组成员使用两种车辆（SUV和轿车）对30个路面部分进行了评级，这些路面部分是在不同的损坏程度下随机选择的。统计分析表明，座位位置、年龄和性别对评分过程的影响不显著。然而，车辆的类型被认为是重要的。本研究新开发的模型解释了80%的县道PSI值的变化（调整后的R-2=0.80）。此外，新的模型似乎提供了更现实的代表性县公路的条件比全州的模型上使用的国家的公路系统。
This paper developed a pavement serviceability prediction model for county paved roads. Most county paved roads were built decades ago without following minimum design standards. The recent increase in industrial/mineral activities in the State of Wyoming required developing a pavement management system (PMS) for local paved roads. The developed PMS used the pavement serviceability index (PSI) as a pavement performance parameter. The proposed PSI model for local roads is based on: international roughness index, pavement condition index (PCI) and rut depth for flexible pavements only. Ten panellists from Wyoming rated 30 pavement sections that were randomly selected at different distresses' levels; using two vehicles (SUV and Sedan). The statistical analysis indicated that the seating position, age and gender are not significant to the rating process. However, the vehicle's type found to be significant. The newly developed model from this study explains 80% of the variations in the PSI values of county roads (adjusted R-2=0.80). In addition, the new model seems to provide more realistic representation of the conditions of county roads than the statewide model used on the state's highway system.
