热压式沥青混凝土桥面铺装设计与性能评价

Design and Performance Evaluation of Hot Rolled Asphalt Bridge Deck Pavement

研究表明热压式沥青混凝土是一种变形能力强、疲劳耐久性和高温性能良好的铺装材料,对桥面铺装具有很好的适应性。目前热压式沥青混凝土在桥面铺装工程中应用不多,国内还未形成热压式沥青混凝土统一的设计方法和技术规范。在国内外热压式沥青混凝土研究的基础上,针对我国桥面铺装的工况特点,对热压式沥青混凝土原材料、级配、油石比等进行研究,确定最佳的热压式沥青混凝土路用性能。

The research shows that the hot-press asphalt concrete is a paving material with strong deformation ability,fatigue durability and high temperature performance,and has good adaptability to bridge deck pavement.At present,hot-press asphalt concrete is not widely used in bridge deck pavement engineering,and the unified design method and technical specifications of hot-press asphalt concrete have not yet been formed in China.Based on the research of hot-press asphalt concrete at home and abroad,this paper studies the hot-press asphalt concrete raw materials,grading and oil-stone ratio to determine the best hot-press asphalt for the characteristics of bridge deck pavement in China.Concrete road performance.
