石灰稳定路面,几年来在我国已经有了成功的理论和经验,为我省无砂石地区开辟了新的广阔的前途。今年我们修筑了20公里的石灰土路面加渣油表面处治,有些问题经过施工和试验,认为是可以提出来研究的。一、石灰剂量的设计问题石灰土的质量和形变模量的大小,主要根据土壤和石灰剂量的大小。我国现行的有关石灰土路面的一些设计和施工规范上对剂量的规定和形变模量大小的关系是很明确的,但是对于石灰的品种、质量,尤其是合活性 CaO+MgO 的多少,对灰土形变模量的大小究竟能影响多大,还是应很好的明确下来的。否则 Lime stabilized pavement, the past few years in our country has had a successful theory and experience for our province without sandstone area opened up a new broad prospects. This year we built a 20 km limestone pavement plus residue surface treatment, some problems after construction and testing, that can be proposed to study. First, the design of lime dose limestone quality and deformation modulus size, mainly according to the size of soil and lime dose. In our country, the relationship between the regulation of dosage and the modulus of deformation is quite clear in some design and construction specifications of limestone pavement. However, for the variety and quality of lime, especially the amount of co-active CaO + MgO, Deformation modulus size can affect how much, or should be well defined. otherwise
