Due to the complexity and uncertainty involved in mass movements, it is not possible to predict their occurrence with accuracy. This uncertainty is due to the space-time variability of physical soil parameters and processes, which determine the boundary conditions of the problem. In this study, we analyzed the influence of spatial variability of the parameters t...

A proper geotechnical site characterization has to identify the geometry of relatively homogeneous zones and define indices, strength and stiffness properties of the soils within these zones. The most widely used in situ test to define the stratigraphical profile and to estimate geotechnical parameters is the Standard Penetration Test (SPT). Although it is widel...

The sustainable use of industrial wastes such as coal fly ash and carbide lime is an effective procedure to enhance the long-term performance of reclaimed asphalt pavement (RAP) under extreme freeze-thaw and wet-dry conditions. This study evaluates the impact of lime content (L) and dry unit weight (gd) on the durability and long-term performance of compacted RA...

This paper presents the effect of adding dihydrate phosphogypsum, which is a byproduct of the production of phosphate fertilizers, on the mechanical behaviour of a lateritic clay typical of Brazil’s Midwest region. Because of the distinction of the mechanical behaviours of both materials, laboratory experiments were conducted with soil, phosphogypsum and mixture...
