在役路面综合受车辆荷载和环境因素的影响，不同区域的路面结构组合和通行情况相同，但路面劣化率不同。由于环境影响的复杂性，到目前为止，环境影响对路面性能的研究进展较少。在已有路面性能方程的基础上，定量分析了环境因素对路面性能的影响，建立了不同地区温度、湿度与路面性能方程之间的关系。在本文研究的5个省市中，环境因素导致的路面寿命差异达25%，湿区路面早期破损现象更为显著。
Pavement in service are comprehensively affected by vehicle loads and environmental factors and the deterioration rates of pavements in different regions are different although their pavement structural combination and traffic are the same. So far, the studies on environmental effects on pavement performance have made less progress because of the complexities of environmental effects. On the basis of previously developed pavement performance equations, this paper quantitatively analyses the effects of environmental factors, and develops the relationships among temperature, moisture and pavement performance equations in different regions. In the case of five provinces and cities noted in this paper, the pavement life differences caused by enviromental factors reaches 25% and the phenomena of early pavement distress are more significant in wet regions.
