摘要
近年来重载交通的日益严重和当前路面结构设计存在缺陷使得很多公路出现早期疲劳开裂和车辙现象。在对重载沥青路面应力分析的基础上,揭示了重载沥青路面的破坏机理,讨论了半刚性基层沥青路面的主要缺点,最后推荐了几种抗重载能力较强的沥青路面结构。
The serious overloading of vehicles and the shortcomings of highway surface designs have left many highways in early fatigue cracks and tracks. On the basis of the stress analysis of overloading asphaltum highway surface, this paper reveals the destructive mechanism of overloading of vehicles on the asphaltum highway surface, discusses the main shortcomings of semi-rigidity basic asphaltum highway surface, and lastly recommends several types of asphaltum highway surface structures that can resist the overloading of vehicles.
