Influence of Aeration and Curing on Shear Strength of Asphalt Stabilized Soil
Abstract: Asphalt stabilization technique is usually used to control and improve poor subgrade soil condition. The subgrade soil is the foundation for the roadway structure, its responsibility is to provide the required stability for the overlaying pavement and to limit the deformation due to traffic load repetitions by furnishing homogeneous stress distribution. In this work, the unconsolidated undrained Triaxial test was implemented for comparatively assessing the impact of asphalt stabilization on …

Effect of Improvement of Collapsible Soils with Bitumen Emulsions on Collapsibility Rate for Varying Degrees of Saturation
Abstract: Collapsible soils are one of many problematic soils in Iraq. Many foundation failure problems that occurred in Iraq are associated with percolation of water; the change in the degree of saturation can affect the stability of these soils and may encounter large volumetric change. A series of tests conducted on collapsible soil using oedometer apparatus and the settlement–time curves are determined accurately, then each test is determined to a different …

Emissivity and Dielectric Behavior of Red Soils of Dhule District at X-band Microwave Frequencies
Abstract: Using X-band (8.2 and 10.5GHz) experimentation, the fluctuation of the dielectric constant (ε’) and dielectric loss (ε’’) of soil samples with different moisture contents has been determined. After reaching a transition point, the value of (ε') grows gradually with moisture content before increasing quickly after that. The emissivity has been estimated from experimentally determined (ε’) using emissivity model for vertical polarization. The findings indicate that as MC/dielectric constant increases, emissivity …
