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.

Comparative Study on Stabilization of Expansive Soil using Cement Kiln Dust and Ceramic Dust
Abstract: In India, expansive soils cover about 20% of total land area, these soils increase in volume (swell) during winter season and decrease in volume (shrink) during summer season. Due to this contradiction behaviour many civil engineering structures constructed on expansive soils get damaged severely, out of which pavement is the most because they are lightweight and extend over large areas. Stabilization of Expansive soil is of most importance, since to …

Effect of Reinforcement on Bearing Capacity of Sand
Abstract: The reinforced earth concept, which is now being evaluated with increased significant encompasses formation of a composite of a soil with tension resistance reinforcing elements such as metallic and nonmetallic strips, bars, rods fibers or nets in the soil. The objective of using the reinforcement is to supress the normal tensile strains in the soil mass through frictional interaction. Flexible nature of reinforced earth mass enables it to withstand large …

Improvement in the Characteristic of Clayey Soil asnSubgrade Stabilized with Natural Fibre :A Review
Abstract: In geotechnical engineering, clayey soil is considered to be the most complicated deposits in the field of construction purposes. Due to its low bearing strength, shearing strength, high compressibility ,volume change and swell-shrink properties it becomes difficult to construct building and pavement structures which cause a great concern for engineers while designing. Construction of pavements should be done as it is strong and durable for their design life by overcoming …
