Influence of Compaction Technique on Shear Strength of Modified Subgrade Soil
Abstract: The subgrade soil is considered as the foundation for the roadway structure, it is responsible to provide the required stability for the overlaying pavement layers and to limit the deformation due to traffic load repetitions by furnishing homogeneous stress distribution. For poor soil condition, grid reinforcement or Asphalt stabilization techniques are usually implemented to control the deformation and improve shear strength of poor granular subgrade soil. In this work, the …

Seismic Bearing Capacity of Strip Footing Subjected to Eccentric Load
Abstract: Reinforced soil bed is improved soil strata from its weak unreinforced original form. By introducing reinforcing ties or strips the soil bed improves on its strength and is rendered less settleable. The compensations of introducing reinforcements have been widely studied by many researchers. The present work has evaluations, formulations and calculations for bearing capacity under certain seismic excitation when the strip footing on reinforced soil was subjected to eccentric loading. …

Predictive Model on Constant Pressure Drop Variable: Area Fluid Flow System in a Pipe
Abstract: The effect of density, pressure drop, and orifice area was examined in this research. The basic equation developed to represent steady-state fluid flow is the Bernoulli equation which assumes that the total mechanical energy is conserved for steady incompressible, in viscid, isotherm flow with no heat transfer or work done. These restrictive conditions can actually be representative of many physical systems. The Bernoulli’s principle was applied in explaining the design …
