【摘要】 基于北京地区路面管理系统中的路面性能数据，结合当地管理经验，辅之以专业理论分析，建立了沥青路面使用性能模型，并用分级（类）时照的方法对主要影响因素作定量分析．利用上述成果，进一步分析了路面结构组合对性能的影响，得到了一些有益的结论，可供路面设计时参考．更多还原

【Abstract】 Based on the pavement performance data measured in Beijing rural highway networks, the relationships among asphalt layer thickness, basecourse types, pavement denections, traffic and long--term pavement conditions(PCI--year) are developed, the effects of pavement structural combinations on pavement performance (PCI--year) are analysed qualitatively, and finally, a new principle for pavement structural combinations is proposed.更多还原
