文章针对我国机场水泥混凝土道面断板破坏频繁的现状,在分析水泥混凝土道面断板危害的基础上,从材料、设计、施工和使用管理等方面揭示了混凝土道面断板的形成内因与外因,并提出了优选原材料、全方位设计、严格混凝土配合比、保证土基和基层质量、适时切缝、改善养护、加强施工与使用管理等防治措施,以期降低混凝土道面断板率,提高道面质量,延长道面使用寿命,实现混凝土道面的“长寿面、低维护”。
In the light of the frequent destruction of airport pavement slab in our country, based on the analysis of the damage of pavement slab in cement concrete pavement, the paper reveals the internal and external causes of concrete pavement slab breaking from aspects of material, design, construction and usage management External factors, and put forward the preferred raw materials, full design, strict mix of concrete to ensure the quality of the foundation and grassroots, timely cutting, to improve conservation, strengthen the construction and use of management and prevention measures to reduce the probability of concrete pavement breaking and improve Pavement quality, extend pavement life, to achieve concrete pavement “longevity noodles, low maintenance ”.
