摘要
路面长期使用性能研究已成为国际道路工程界普遍重视的一项基础性研究。在分析有关试验路路面使用性能长期观测数据的基础上,根据中国沥青路面的设计方法和沥青路面的使用性能情况,结合中国沥青路面的破坏特点,提出了在现行的弯沉设计指标基础上,增加路面疲劳开裂和车辙作为沥青路面长期使用性能的研究指标,认为这两项指标能够反映较长时间内行车荷载及自然因素对路面的影响,并能有效地反映路面的使用性能变化情况。
The study of long term performance of pavement is now becoming to be an important field in road research. With the analysis to the data of pavement performance from the test roads, two criteria, fatigue and rut, were put forward as the long term performance research criteria according to the asphalt pavement design criteria and also the practically performance of the pavement in use. The two criteria, together with the design criteria, deflection, can reflect the influence of vehicle and environment on pavement, and present the change of performance of pavement.
