The knowledge and characterization of aggregate stability are relevant to select adequate management avoid its degradation. Thus, this study aimed characterize the spatial variability in cohesive soils under crop conservation systems. experiment was performed two different areas soybean production: no-tillage System (NTS) livestock farming integration system (LFI), In each production area, a sa...

The stochastic gully erosion model (STOGEM) is based on a combination of deterministic mechanics and description the control factors. main proposition in that depth active surface layer eroded cohesive soil equal to one particle diameter, deposition particles negligible. rate at bed calculated directly from equation balance between driving resistance forces acting flowing water using probabilit...

Test rolling is a quality assessment technique performed on road construction materials to verify consistency prior to paving. In this test, the depth to which the wheels of a heavy vehicle penetrate the material is used as a measure of quality. Current test rolling specifications are based largely on empirical data. In this paper, theoretical models are presented for the case of a test roller ...

Soft clays are defined as cohesive soil whose water content is higher than its liquid limits. Thus, soil-cement mixing is adopted to improve the ground conditions by enhancing the strength and deformation characteristics of the soft clays. For the above mentioned reasons, a series of laboratory tests were carried out to study some fundamental mechanical properties of cement stabilized soft clay...
