温拌沥青合成沸石外加剂性能表征研究

Study on Performance Characterization of Synthetic Zeolite WMA Agent

温拌沥青混合料由于其拌合温度较低,能够有效地减少能源的消耗及废弃的排放,并且有较好的路用性能,应用前景十分广阔。外加剂是制约温拌沥青混合料性能的关键。利用X射线衍射、热稳定检测和激光粒度分析等方法对两种国产温拌剂(合成沸石)以及国外常用的温拌剂Advera的内部结构、组成性能表征进行测试分析,通过对比国内外合成沸石温拌沥青剂的性能指标,定量地分析国产合成沸石类沥青温拌剂的产品质量,为推进发泡型温拌沥青技术在我国的发展及产品的国产化探索提供理论依据。

Due to lower mixing temperature, effective reduction of energy consumption and CO2 emissions, and good road performance, warm mix asphalt has very broad application prospect. In this paper internal microstructure and properties of two kinds of domestic synthetic zeolite agent of warm mix and Advera warm mix have been studied. By comparing the performance characterization of these synthetic zeolites, the product quality of domestic synthetic zeolite agents of warm mix asphalt can be analyzed quantitatively .
