高寒地区水泥混凝土路面裂缝防治研究

Prevention of Cracks on Cement Concrete Pavement in Alpine Area

为更好地总结高寒地区水泥混凝土路面的裂缝防治处理措施,文章结合高寒地区昌都公路项目的施工经验,对高寒地区水泥混凝土路面裂缝产生的原因进行分析,提出了混凝土路面裂缝的局部裂缝修补、表面龟裂的修补、贯穿性裂缝修补及严重的错台裂缝处理四方面的裂缝治理措施,并提出了混凝土路面的裂缝预防措施。

In order to better summarize the crack prevention and treatment measures of cement concrete pavement in alpine area,this article combines the construction experience of the Changdu highway project in alpine area to analyze the reasons for the cracks in the cement concrete pavement in alpine area.Four crack control measures are proposed:local crack repair of concrete pavement cracks,surface crack repair,penetrating crack repair,and serious dislocation crack treatment,and crack prevention measures for concrete pavement are also proposed.
