摘要

摘要毫无疑问,沥青混凝土路面的车辙被认为是道路使用者和道路管理部门在路面性能和安全方面面临的一个主要困境。车辙是车轮路径中的一种碗状凹陷,随着负载应用次数的增加而逐渐发展。除了夏季路面温度高之外,重轴载也加剧了车辙问题。根据AASHTO关于柔性路面的设计方程式 在没有其他损坏的情况下,车辙深度将使相对较新的路面目前的可用性指数从4.2降低到2.5。随着可用性的下降,路面的整个使用寿命已经丧失。因此,研究减少车辙的机理、可能的原因以及技术,以提供较长的使用寿命和安全的道路,是至关重要的。为此,有必要进行这项研究,主要是对现有文献进行彻底审查,以突出研究人员和路面工程师在车辙机理、测量和标准方面的一些关键点,包括车辙的内在(混合变量)和外在(交通和温度)因素、材料特性、,试验方法和预测方法,以及尽量减少沥青混凝土路面车辙破坏的可能方法。到目前为止,这项研究试图通过深入回顾沥青混凝土中的车辙来填补文献中经常只涉及车辙的单一方面的空白,从而对这一主要病害类型有一个全面的了解。

A review of rutting in asphalt concrete pavement
Abstract Undoubtedly, rutting in asphalt concrete pavement is considered a major dilemma in terms of pavement performance and safety faced by road users as well as the road authorities. Rutting is a bowl-shaped depression in the wheel paths that develop gradually with the increasing number of load applications. Heavy axle loadings besides the high pavement summer temperature enhance the problem of rutting. According to the AASHTO design equation for flexible pavements, a 1.1 in rut depth will reduce the present serviceability index of relatively new pavement, having no other distress, from 4.2 to 2.5. With this amount of drop in serviceability, the entire life of the pavement in effect has been lost. Therefore, it is crucial to look at the mechanism, possible reasons, as well as techniques, to reduce the rutting in order to offer long service life and safe roadways. To this end, the need has been arising for this research which deals mainly with a thorough review of the existing literature to highlight some key points for the researchers and pavement engineers related to rutting mechanism, measurement, and criteria, both intrinsic (mixture variables) and extrinsic (traffic and temperature) contributory factors to rutting, material characterization, test methods, and prediction methodologies, as well as possible ways to minimize the rutting distress in asphalt concrete pavement. So far, this research attempts to bridge the gap in the literature that frequently only addresses a single aspect of rutting by providing an in-depth review of rutting in asphalt concrete and thereby offers a complete comprehensive understanding of this major distress type.
