摘要
鉴于疏港路高架混凝土桥的使用特点及设计要求,对原桥面铺装设计方案进行优化,提出浇筑式沥青+改性沥青SMA的铺装方案。经综合论证,该方案相对于原铺装方案,综合性能有较大提高,对于提高桥梁的通行能力和保护结构有重要作用。
In view of application features and design requirements of concrete viaduct on port-release roads, this paper optimizes the original design plan for pavement of deck, and proposes a paving plan by means of casting asphalt ＋ modified asphalt SMA. After comprehensive demonstration, this plan in comparison with the original one has greatly improving integrity, playing an important role in improvement of traffic capacity of viaduct and protection of structures.
