钢桥面浇筑式沥青混凝土配合比设计实例与施工应用

Design Practices and Construction Application on Steel Deck Asphalt Concrete Mix Proportion

浇筑式沥青混凝土一般应用于钢桥面铺装下面层施工,具有不透水性、耐久性、抗冲击性好、适应变形能力强等特点,结合永川长江大桥钢桥面施工实例,从原材料特性、配合比设计、检验指标等方面探讨了其独特的设计方法,并对浇筑式沥青混凝土拌合、运输到摊铺等环节结合施工应用提出具体要求和质量控制措施,对常见问题提出预防措施。

Grouting asphalt concrete is mainly utilized in bottom pavement construction of steel deck plate paving with the characteristics of waterproofness,endurance,shock resistance,adaptability,and strong deformation force. Combining to Yongjiang Yangze River steel deck plate paving construction project,this article analyzed distinctive design on the section of raw material specialty,mix proportion design and test indicators; and proposed definite requirements and quality control measures on procedures from asphalt concrete mixing,transportation to paving integrated to construction applications,thus presenting preventive actions on common problems.
