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、外原因,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控措施,以期降低机场混凝土道面的断板率,提高道面质量,延长道面使用寿命,实现机场混凝土道面的“长寿面、低维护”。
In view of the frequent destruction of airport pavement slab in China, based on the analysis of the hazards of the pavement slab in the concrete pavement, the internal and external causes of the concrete pavement slab are revealed from the aspects of material, design, construction and use management , And put forward the prevention and control measures such as optimizing the raw material, omni-directional design and strict concrete mix ratio, ensuring the quality of foundation and grassroots, cutting at proper time, improving maintenance, strengthening construction and use management, with a view to reducing the breaking rate of airport concrete pavement , Improve the pavement quality, extend the service life of the pavement and realize the “longevity surface and low maintenance” of the airport concrete pavement.
