公路低噪声沥青混合料材料设计与应用

Design And Application Of Highway Low Noise Asphalt Mixture

主要探讨低噪音沥青混合料的研究和应用工作。首先,分析低噪音沥青路面的特点,研究交通噪音分类及其产生机理,提出解决噪音的主要措施;其次,对比分析国内外传统的低噪音沥青混合料矿料的级配范围,提出改进的矿料级配范围,并进行相应的低噪音沥青混合料设计。在某公路上铺筑了试验段,探讨低噪音沥青混合料的施工方法,试验段与普通路段的对比检测结果显示本研究的设计具有良好的效果。

Mainly discusses the research and application of low noise asphalt mixture work. Firstly, analyzes the characteristics of low noise asphah pavement, the traffic noise classification and generation mechanism, puts for- ward the main measures to solve the noise; secondly, comparative analysis of the domestic and foreign traditional gradation range of low noise asphalt mixture, the aggregate grading range improved, and the design of low noise asphalt mixture corresponding. In a road paved the test section, discusses the construction method of low noise asphalt mixture, test results contrast test section and general section has shown good results in the design of this study.
