乳化沥青混合料配合比设计方法研究

Study on the Design Method of Emulsified Asphalt Mixture

要想实现乳化沥青混合料在结构、路用性能、环保等方面的技术优势,核心是配合比设计,根据乳化沥青混合料的使用环境,在借鉴和总结国内外相关应用经验和研究成果提出基于劈裂强度和无侧限抗压强度峰值确定乳化沥青混合最佳油乳化沥青用量,试验结果表明,经室内加速加载、SCB、三分点加载疲劳试验验证,该法具有较好的技术优越性,研究成果可对今后同类型工程设计提供技术参考。

In order to achieve emulsified asphalt in the structure, road performance, environmen- tal protection and other technical superiority aspects , the core technology is mix design. Based on the use of emulsified asphalt environment, learn from experience and research and summarized and related applications based on the results of proposed splitting strength and unconfined compressive strength peak determining the optimal mix of emulsified asphalt oil emulsified asphalt content, test results showed that the indoor accelerated loading, SCB, one-third point loading fatigue tests, show that this method has good technical superiority, the research results can provide technical reference for future projects of the same type design.
