Study of the Properties of Wicking Geotextile: Mudstone Mixed Soil Subgrade in Cold Regions
Mudstone mixed soil is a kind of mixed soil formed by the mixture of mudstone and surface soil. The disintegration properties of mudstone in contact with water have led to a significant decrease in the weak stability of mudstone mixed soil, so it is often treated as a kind of construction solid waste in engineering construction. In order to promote the process of resource utilization of construction waste, improve the mechanical and stability of mudstone mixed soil, and make it meet the road performance requirements of subgrade in cold areas, the benefits of the wicking geotextile were quantified via numerical simulations. The performances were compared for road embankments with and without the wicking geotextile. The results showed that wicking geotextiles can effectively reduce the moisture content of the subgrade, and the moisture content of the bottom layer of the upper road bed and the bottom layer of the lower road bed are reduced by 45.4% and 41.6%. Maximizes subgrade performance when wicking geotextiles are placed at the bottom of the roadbed. Based on research results, the mudstone soil mixture, as a solid waste, can be used as a filling material in cold regions with the application of the wicking geotextile.
