Roadbed structure and roadbed construction method
The roadbed structure comprises a waterproof heating layer, a waterproof heat preservation layer and an upper roadbed layer, and edge covering soil layers are arranged on the two sides of a roadbed; the waterproof heat preservation layer comprises a drainage cushion layer, an XPS heat preservation plate and a lime soil cushion layer. The upper roadbed layer comprises a gravel soil layer, a bubble mixed light soil base layer and an asphalt pavement; the waterproof heating layer comprises waterproof walls on the two sides of the roadbed, and a heating facility is arranged between the waterproof walls. During construction, shallow salinized soil is removed to form a foundation pit, and after a cutoff wall and a heating facility are arranged in the foundation pit, salinized soil is backfilled; then a drainage cushion layer, an XPS heat preservation plate, a lime soil cushion layer, a gravel soil layer, a bubble mixed light soil base layer and an asphalt pavement are laid in sequence, and finally heat preservation protection ways, edge covering soil layers and drainage channels are arranged on the two sides of the roadbed. The conditions of cracking, sinking and the like of the roadbed of the salinized soil road section due to environmental factors can be effectively improved, the service life of the road is prolonged, and the driving safety is improved.
本发明公开的一种路基结构及路基施工方法，包括隔水加热层、防水保温层和上部路基层，路基两侧设置包边土层；防水保温层包括排水垫层、XPS保温板和石灰土垫层；上部路基层包括碎石土层、气泡混合轻质土基层和沥青路面；隔水加热层包括路基两侧的隔水墙，隔水墙之间设有加热设施。施工时，清除浅层盐渍土形成基坑，在基坑内设置隔水墙和加热设施后回填盐渍土；然后依次铺设排水垫层、XPS保温板、石灰土垫层、碎石土层、气泡混合轻质土基层和沥青路面，最后在路基两侧设置保温护道、包边土层和排水渠即可。本发明能够有效改善盐渍土壤路段路基受环境因素，出现开裂、下沉等情况的出现，延长了道路的使用寿命，提高行车安全性。
