摘要
通过试验方法,研究了施工温度对泡沫沥青混凝土性能的影响,以及在低温季节条件施工下提高泡沫沥青混凝土性能的措施和建议。研究结果表明:泡沫沥青混凝土性能受气温影响较大,适合在温度较高的夏季施工;在低温季节,调整级配和沥青含量对提高性能贡献较小,建议采取延长养生周期和增加压实功的方法提高泡沫沥青混凝土的性能。
This paper studies the influence of construction temperature on the property of foamed bitumen concrete, and the measures and suggestions to improve the property of foamed bitumen mixtures in the low temperature season of construction condition. The results show that property of foamed bitumen concrete is greatly influenced by the temperature, and is suitable to construct in higher temperature of summer. In the low temperature season, the adjustment of the gradation and the asphalt content improves the concrete property a little. It is to propose the method of lengthening the curing period and increasing the compaction energy to improve the property of foamed bitumen concrete.
