在城市的建设发展中,道路建设占据着举足轻重的地位。随着社会的不断发展,人们的生活生产水平不断提高,因此也给城市的交通道路提出了更高的要求。在城市的交通道路建设中,进行路基施工时通常采用石灰土作为路基修筑材料。石灰土是我国南方亚热带地区石灰岩母质发育的土壤,一般质地都比较粘重,剖面上或多或少都有石灰泡沫反应,但土壤颜色却各不相同,常见的有红、黄、棕、黑四种,由于石灰土的粘重性得到了城市道路建设工程师的青睐,本选用作为市政道路的基层。但是就目前的市政道路石灰基层施工的实际情况而言还是存在着许多的不足,本文针对石灰土的特性拟出了相关的石灰基层施工方案,希望能够起到抛砖引玉的效果,并且希望对我国的市政道路建设工作做出理论性的参考。
In urban construction and development, road construction occupies a pivotal position. With the continuous development of society, people’s living standards are constantly improving, and therefore higher demands are placed on urban transport routes. In the construction of traffic roads in urban areas, limestone soil is usually used as subgrade construction materials for subgrade construction. Lime soil is a kind of soil with developed limestone parent material in the subtropical region of China. Generally, the texture is relatively sticky. There is lime foam reaction more or less in the section, but the soil color is different. Common red, yellow, brown and black Four, due to the stickiness of lime soil has been favored by urban road construction engineers, this election as the grassroots municipal roads. However, there are still many deficiencies in the actual construction of limestone in municipal roads. In this paper, the related limestone construction schemes are proposed according to the characteristics of limestone soil. Hopefully, Municipal road construction to make a theoretical reference.
