摘要
通过调查河北省部分高速公路完工通车2年后的使用情况,发现水泥混凝土桥面铺装易出现混凝土开裂松散、唧浆等病害,严重影响行车安全及舒适性。主要从施工、设计的角度对引起水泥混凝土桥面铺装破坏的原因进行了分析,对其防治措施谈几点看法,仅供同行参考。
Investigations into the operation status of a few expressways within 2 years after opening to traffic reveal that defects such as concrete cracking, segregation and water-squeezing could easily occur on cement concrete decks, resulting in serious impacts on vehicle safety and riding comfort. This paper, from the perspectives of construction and design, gives an analysis of the causes of damages occurring on cement concrete decks and recommends a few preventive and corrective measures against these damages.
