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 …

Improvement of Sand Subgrade Soil Strength with Geogride Reinforcement
Abstract: The quality and life of pavement is greatly affected by the type of sub-grade, sub base and base course materials. The most important of these are the type and quality of sub-grade soil. But in Iraq most of the flexible pavements are needed to be constructed over weak and problematic sub-grade. Flexible pavements constructed on weak subgrade with low California bearing ratio (CBR) are required to increase its total thickness. …
