摘要
乳化沥青在常温下具有良好的流动性,可以改善原沥青的使用性能,具有节约能源、减少环境污染、改善施工条件等优点,但乳化沥青的性能很大程度上受原沥青的成分组成和化学结构的影响,而使乳化沥青在道路工程上不能适应现代交通流量大、重轴载、高速度的需要,制约乳化沥青的应用。
The emulsified asphalt at room temperature with good liquidity, to improve the performance of the original use of asphalt, with energy conservation, reduce pollution and improve the construction conditions, etc., but the performance of emulsified asphalt to a large extent by the composition of the original group of asphalt and chemical structure of, leaving emulsified asphalt in road projects can not meet modern traffic large, heavy axle-load, high-speed needs, restricted the application of emulsified asphalt. Therefore, to the use of modified asphalt emulsion asphalt emulsion added new content to the application of emulsified asphalt to bring a broader space.
