1960年以来,炉碴石灰土在沈阳、哈尔滨等地得到了比较广泛的应用。使用情况表明,炉碴石灰土也是一种经济而有效的防治道路翻浆措施,在城市道路上更可以广泛采用。附表1是哈尔滨市炉碴石灰土和石灰土历年观测结果的对比。廿道街第二段和第三段同为地下水位很高的第Ⅲ地带类型,石灰土铺在中砂层上,炉碴石灰土铺在细沙层上。由于细沙吸水性比中沙强,因而第三段的水文条件应比第二段稍差。廿道街第五段和经纬街也同属水文地质条件不良的路段,石灰土和炉碴石灰
Since 1960, limestone furnace slag in Shenyang, Harbin and other places have been more widely used. The use cases indicate that the ballast limestone is also an economical and effective measure to prevent and deal with road tainting and can be more widely adopted on urban roads. Schedule 1 is a comparison of the observed results of calcined limestone and lime soil in Harbin. The second and third sections of Bode Road are of the third type with very high groundwater table. Lime soil is laid on the middle sand layer, and lime-clay of the ballast is spread on the fine sand layer. Since the fine sand is more absorbent than Zhongsha, hydrological conditions in the third section should be slightly worse than those in the second section. The second section of Bunge Street and Jingwei Street also belong to the sections with poor hydrogeological conditions. Lime soil and slag lime
