公路沥青路面使用性能灰色综合评估

公路在交通荷载和自然环境的共同作用下，路面使用性能会随着时间推移而日益衰减，从而直接影响车辆的行驶速度和运输的安全性、经济型和舒适性。为了评估和预测路面使用性能状况，便于进行科学地养护和管理，文章系统地提出了公路沥青路面使用性能评价的指标体系和分级标准，建立了沥青路面使用性能灰色综合评价模型。最后，结合选取路段的实测数据与规范推荐评价方法进行了应用与对比分析。

Synthetical Gray Evaluation of Asphalt Pavement Performance

The synthetical gray evaluation of asphalt pavement performance composes of the most part of the highway maintenance and economic analysis in management. Under long-term effect of traffic loads and environmental impacts the pavement performance will debase with time, which has direct influence on driving safety and comfort with economic implications.In order to evaluate and predict the present and future, performance, the paper discusses and proposes some evaluation indexes which can reflect road conditions systematically, and establishes an evaluation model for asphalt pavement based on the gray system theory.In the end, the paper gives a case study using the gray model which is applied to four asphalt roads selected from Henan Province, and analyzes its evaluation result in comparison with the specification model suggested by the Chinese Highway Maintenance Code in 2001. The result shows that the gray evaluation model is more scientific and applicable than ever before.
