水泥混凝土路面疲劳破坏及其对策研究

摘要

水泥混凝土路面的破坏主要表现为疲劳破坏.研究表明,混凝土的强度和路面表面的平整度,对路面的疲劳寿命影响很大.建议采用混凝土的＂双向拉伸强度＂作为混凝土路面板的厚度设计验算标准,并在施工中尽量整平路面,提高路表的平整度指标.%the destruction of the cement concrete pavement mainly is fatigue damage.The research shows that the strength of cement concrete pavement and its roughness influence the fatigue life very much.＂Two-way tensile strength＂ is suggested as the standard of concrete pavement board’s thickness of checking and design,as far as possible to leveling the pavement in construction and improves the roughness index of the pavement.
