Collapsible soils such as loess, sustain substantial stress under dry condition. However, they experience a high and sudden decrease in their volume by reaching to their critical moisture content. As a result, their natural condition is not suitable for construction works if the possibility of the exposure of the soil to excessive water is present. This research presents the utilization of an innovative method for stabilization and improvement of Gorgan loessial soil. This method uses Electrokinetics and Nanomaterials as an in-situ remedial measure to instigate additives to move through soil pores through ion migration phenomena. In order to assess the deformation and strength behavior of improved collapsible soil and comparing with those of unimproved soil, several Unsaturated Oedometer tests under constant vertical stress and varying matric suction were performed. The result showed the effect of matric suction on the behavior of both improved and unimproved samples. The resistant of the soil was highly dependent on the water content and matric suction. The Oedometer tests on samples improved by 3% Lime and 5% nanomaterials showed considerable improvement of Collapse potential. Results also showed that stabilized samples experienced notably lower volume decrease under the same induced stresses.

The designed properties of Hot Mix Asphalt (HMA) pavements, known as flexible pavements, are subjected to change during production and construction stages. Therefore, most of the times the final product is not the exact reflection of the design. In almost any highway project, these changes are common and likely to occur from different sources, by various causes, and at any stage. These changes often have considerable impacts on the long-term performance of a project. The uncertainty of the traffic and environmental factors, as well as the variability of material properties and pavement structural systems, are obstacles for precise prediction of pavement performance. Therefore,...

Many efforts have been done in the field of geotechnical engineering to evaluate and theorize the consolidation behavior of the soil in both saturated and dry conditions. However, similar efforts in the case of unsaturated soils are fairly limited. This research details the developed theories for the long-term deformation of unsaturated soils with a particular emphasis on the importance of flow law and elasticity at different phases of the soil. The state of the art in the field of Multiphysics consolidation is summarized in this paper. A series of the widely used mechanical concepts for unsaturated consolidation disintegrated in this study and elaborated in detail. This discretization of the current theories allowed further investigation of the pros and cons of each theory. A critical review of the literature assessed the applicability of the unsaturated consolidat...

To get a better insight about the process, testing the actual rock samples can be extremely imperative. This study, indeed, attempts to evaluate the fracture toughness of actual rock samples using two different test protocols, i.e., Cracked Chevron Notched Brazilian Disc (CCNBD) and Semi-Circular Bend (SCB). The results indicate that similar behavior is observed for the samples under the two tests. However, due to the geometry, created a crack, and the loading conditions of the prepared samples, the fracture occurs for the SCB samples under a less needed force. The results also indicate that the SCB test samples yield more fracture toughness.
