摘要
在参考热拌沥青混合料的试验方法和控制指标的基础上,针对一种常温沥青混合料强度的形成特点,对其强度性能、黏聚性能、高温稳定性、储存稳定性设计了相应的测试方法,提出了相应的技术指标及指标建议值。试验结果表明,该常温沥青混合料具有较好的高温稳定性、储存稳定性;初期强度较小,但成型强度满足低等级道路路面要求。研究成果可为低等级道路常温沥青混合料在工程中的应用提供技术参考。
The evaluation indexes and technical requirements of a new normal temperature asphalt mixture about strength properties, cohesion performance, high temperature stability, and storage stability performance based on referring to the test methods and control targets of hot mix asphalt are proposed in this study. The results indicate that the normal temperature asphalt mixture have good high temperature stability and storage stability performance, while its early strength is small, but the molding intensity satisfies the requirement of low-grade road pavement. The research results can provide technique guidance for the engineering application of normal temperature asphalt.
