机场沥青道面管理与预防性维护对策

为了提高机场沥青道面的使用寿命,降低其养护与管理费用,分析了其类型、特性与应用现状,研究了其主要影响因素与破坏机理,提出了相应的管理与预防性维护对策。研究发现:建立严格的管理机制,禁止超载,加强日常维护与培训飞行员正确使用道面是减少破损的有效方法;对现有病害类型,提出了表面处治及改性稀浆封层等薄层修补维护方法;根据不同季节的气候特点与水温条件的变化规律,按照"预防为主,防治结合"的原则,针对季节性病害根源,因地制宜地采取有效的技术措施,做好季节预防性养护工作;加强道面状况评估,把握最佳养护时机和制定合理的养护标准可有效提高机场沥青道面的使用性能。

Management and preventive maintenance countermeasures of airport asphalt pavement

In order to improve the service life of airport asphalt pavement and reduce the expenses of maintenance and management,different types,characteristics and actual application status of several asphalt pavements were analyzed,main influencing factors and damage mechanisms were studied,and relevant countermeasures of management and preventive maintenance were put forward.Analysis result shows that constituting strict management mechanisms,forbiding overload,enhancing daily maintenance and training pilots to use pavement reasonably are effective methods to reduce pavement damage;thin surface repair methods of topdressing and covering with modified asphalt mortar are put forward for existing damage styles;based on climate characteristics in different seasons,the change laws of water and temperature conditions,and the principle of putting prevention first and combining prevention with treatment,efficient technical measures aiming at local conditions are taken for seasonal pavement damage,seasonal maintenance work should be done well;enhancing pavement status evaluation,taking optimal maintenance occasion and constituting reasonable maintenance standards can effectively improve the service performance of airport asphalt pavement.14 refs.
