桥面横向收缩开裂发生在施工过程中和施工后不久。它允许裂缝形成，随后允许水和其他元素进入甲板的混凝土基质，最重要的是落在下面的支撑结构上。这导致支撑结构严重受损。本文介绍了在混凝土桥面内采用涂有密封胶的脆性管控制和修复横向收缩裂缝的现场应用设计。
Transverse shrinkage cracking of bridge decks occurs during and shortly after construction. It allows cracks to form and later allows water and other elements to enter the concrete matrix of the deck and most importantly to fall onto the supporting structure below. This leads to significantly damage of that support structure. This paper describes a field application of the design for an in-situ means of controlling and repairing transverse shrinkage cracking, by utilizing brittle tubes with sealants in the concrete deck.
