用水泥结合料稳定土(包括各种集料),在国外,早已在道路基层、飞机场跑道基层、小交通量路面的面层、水利工程和房屋工程中得到广泛的采用;我国交通部门在一些援外的公路工程中,也较多地采用了水泥稳定土来作为沥青路面的基层;在国内,一些兄弟省(区)公路部门在用水泥土作为油路基层方面也作了不少研究。国内外的实践都证明:水泥稳定土是一种强度高、水稳性好的新型建筑材料。我们学习了援外工程采用水泥土作为沥青路面基层的经验以后,在1977年冬
Stabilized soil (including various aggregates) with cement-bound materials has been widely adopted abroad in the grassroots level of the road, the base of the airport runway, the surface of small traffic pavement, water conservancy projects and housing projects; the transport sector in China Some foreign-aid highway projects also use more cement stabilized soil as the base of asphalt pavement. In China, some provincial (district) highway departments made a lot of researches on cement soil as the oil road base. Practice both at home and abroad have proved that cement stabilized soil is a kind of new building material with high strength and good water stability. We learned from the experience of using cement soil as the grassroots of asphalt pavement in the aid project of foreign aid. In the winter of 1977
