- Abstract:
- In order to expound the characteristic and the formation of road soil,this paper took an existing road area soil as a typical case study,which lies in Xi-yu expressway Heyang section.Compared with the undisturbed natural soils,investigated and analyzed the expressway road area soil,and summarized the formation and characteristic and its limit factors as the following: (1) Worsening of soil physical properties is a general characteristic.(2) Soil organic matter and nutrient were scanty,and the pH value of road soil were higher than local natural soil.It has the trend to be the alkaline soil.(3) The soil component was quite complex,too much invasive matter were intermingled.(4) The valid soil depth was limited and its higher rigidity made it’s difficult for plant to take root.(5) Because of the continuing exposing to the exhaust gas,it had more likelihood to be polluted by heavy metals.
