| 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 ... |
