水泥混凝土路面与基层接触状况不仅影响路面接缝间距和接缝宽度 ,同时也影响混凝土路面早期开裂。该文从混凝土路面与基层接触界面破坏试验着手 ,分析基层对面板的约束状况 ,为水泥混凝土路面设计提供参考。 Cement concrete pavement contact with the grass-roots level not only affects the pavement spacing and seam width, but also affect the early cracking of concrete pavement. This paper starts from the failure test of the contact interface between concrete pavement and grass roots, analyzes the constraints of the grass-roots to the panel, and provides a reference for the design of cement concrete pavement.
