摘 要:介绍了国内外乳化沥青在土壤治理方面的主要用途及应用概况。阐述了沥青乳化及其土壤改良机理。实践表明 ,它不仅用于土壤改良 ,还可用于水土保持及防风固沙等。当用于土壤改良时 ,可使水稳定性团粒增加 3 0 %以上 ,使地表下 5厘米处地温日平均提高 2~2 .5℃ ;如果用于治沙 ,能使沙土表层形成良好的结构 ,促进植物生长 ,同时还可降低虫害及鼠害 ,提高植物的成活率等 。The general application condition and mainly usage of emulsion asphalt in agriculture have been presented in this paper.The soil improvement mechanism of emulsion asphalt and its development tendency have been also introduced simply.The practice indicated that the emulsion asphalt can be used not only for soil improvement,in which the amount of soil particles in water stability and soil temperature at 5 cm depth can be increased by 30% and 2 to 2 5℃ respectively,but also for sand control,in which the sand soil surface can form the good constructrue in order to promote plants growing,prevent plant diseases and insect pests,and increase the plant livability and so on.
