黑龙江省松嫩平原大片地区缺乏砂石材料,因此利用石灰土作为路面承重层,用渣油表面处治,经二年来实践证明效果良好,已在生产中推广。现将几个问题简述如下: 一、在石灰土路面上进行渣油表面处治,必须保证石灰土拌和均匀;在最佳含水量时达到最大密实度;石灰要求完全消解,若有小灰块则在路面铺筑后会产生小块鼓包,影响路面平整度。 Because of the lack of sand and gravel material in the vast area of ​​Songnen Plain in Heilongjiang Province, limestone soil is used as the bearing layer of the pavement and treated with the residual oil. After two years of practice, the effect has been proved to be good and has been promoted in production. Now a few questions briefly as follows: First, in the lime soil surface treatment of residual oil, limestone soil must ensure uniform mixing; at the optimum moisture content to achieve the maximum density; lime requires complete digestion, if small ash After the pavement will produce a small drum kits, the impact of road roughness.
