| 摘 要： | 公路沥青路面环境性能研究一直是路面长期使用性能研究的一个重要方面，路面结构不仅要满足行车荷载的要求，还要适应所处的自然环境，因而，在评价沥青路面长期使用性能时应考虑路面的环境性能，本文综合分析国内外相关的研究，采用路面最高温度Tmax和潮湿系数W作为评价参数，建立了公路沥青路面环境性能的评价指标PEI和相应的分级标准，并将此模型应用于河南省高等级沥青路面环境性能的评价。实例实际计算表明，该评价指标能较好的反映路面环境性能随路龄时间的变化状况。

| Abstract: | The function of highway environment is an important aspect of road long-term performance research. Because the highway construction is seasoned with not only carrying loads, but also the nature environment. The highway environment should be considered in the evaluation of the road structure performance. This paper has analyzed the domestic and international related researches, and suggested two indexes for established evaluation model such as the highest road temperature and the damp coefficient. In the end, the highway environment evaluation model has been applied in some asphalt freeways in Henan. |
