Fig.1  Stress strain relation and the consequences for elastic or plastic soil behavior (e= void ratio, σn= stress). The precompression stress defines the internal soil strength and the resilience limit.
Fig.2  Effect of aggregate type on the accessibility of surfaces (particle or pore walls) as well as the consequences for soil strength or rigidity. Hom= Homogenous, Coh= Coherent, Pris= Prismatic, Pol= Polyhedral, Sub= Subangular blocky, Cru= Crumbly, Pla= Platy structure.
Fig.3  Relative changes of soil properties within the virgin compression= plastic range. During the recompression load range remain the properties and functions mostly unchanged while in virgin compression load range induce increasing stresses applied (σn= stress) changes in: AC= Air capacity, CH4 = Methane concentration, CO2 = Carbon dioxide, Eh= Redox potential, FP= Fine pores, Ds= Gas diffusion, ks= Saturated hydraulic conductivity, and PAW= Plant available water.
