摘要
结合高速公路实际工程,在室内外试验的基础上,针对泡沫沥青冷再生关键技术开展研究,分析了泡沫沥青混合料的关键影响因素,认为0.075mm细集料通过率宜控制在4%左右,掺入水泥后可以显著提高混合料的水稳定性,用24h劈裂强度可作为现场施工质量控制指标。
The influence factors of mix design of foamed asphalt mixtureare analyzed.It is concluded that the pass rate of fine aggregate with 0.075 mm is generally controlled at about 4%,the cement can significantly improve the water stability of the mixture,and the splitting strength of 24 hours can be used as the index of field quality control.
