摘　　要：随着我国沥青路面技术的发展,对沥青路面结构及其性能变化的研究也在逐步深入,其中长寿命沥青路面已被大量证明可有效提高路面的使用性能和寿命。基于现有长寿命路面设计理论和性能预测方法等相关理论,以北京市华西路为例,进行了不同路面结构的力学和性能分析,验证了路面结构对路面性能和病害发展的影响,并根据实际检测数据拟合得到了华西路路面性能指数预测模型,检验了PCI、RQI等相关指标的精度,得到了在类似的交通和环境条件下,半刚性基层长寿命路面结构具有更好的路面性能,更适于荷载较大的路面设计的结论。相关分析和结论可为沥青路面结构性能研究和路面养护规划提供参考和借鉴。With the development of asphalt pavement technology in China,research on asphalt pavement structure and performance change has been also gradually deep-going.Long-life asphalt pavement has been widely proved to effectively improve the performance and service life of pavement.Based on existing theories such as long-life pavement design and performance prediction methods,taking Huaxi Road in Beijing as an example,mechanical analysis and performance analysis of different pavement structures were conducted to verify the impact of pavement structures on pavement performance and disease.A prediction model for Huaxi Road pavement performance index was obtained by fitting actual test data to test the accuracy of PCI,RQI and other related indicators.The conclusion is drawn that the semi rigid base long-life pavement structure has better pavement performance and is more suitable for road design with heavy loads under similar traffic and environmental conditions.The relevant analysis and conclusions can provide reference and guidance for the study of asphalt pavement structural performance and pavement maintenance planning.
