Impact Of Lateral Swell Pressure On Retaining Structure Design Using Expansive Cohesive Backfill
(Civil & Environmental Engineering, 2008-08-08)
Since cohesive soils are difficult to drain once becoming saturated, in order to reduce lateral earth pressures exerted by saturated cohesive soils on retaining structures, retaining wall designs most always specify use ...
Ductile Lightweight Concrete For Lightweight Structural Application
(Civil & Environmental Engineering, 2008-08-08)
This study developed a ductile concrete for precast wall systems which are capable of resisting high wind in excess of 500 mph. The developed concrete mix design consists of sand, cement, glass fiber, and a foaming agent ...
Effects Of Calcium-based Treatment On Organic Soil Behavior
(Civil & Environmental Engineering, 2008-09-17)
Organic soils are found in many places around the world. Organic soils undergo large secondary settlements depending on the amount of organic matter present in the soil Organic soil is a mixture of finely divided particles ...
Studies On Volume Change Movements In High PI Clays For Better Design Of Low Volume Pavements
(Civil & Environmental Engineering, 2008-09-17)
Numerous low- to medium-volume roads such as Farm Market (FM) roads constructed on expansive clay subgrades, especially in the eastern and central Texas, encounter severe pavement cracking and premature loss of serviceability. ...
Subsurface Investigations Using High Resolution Resistivity
(Civil & Environmental Engineering, 2008-09-17)
Electrical resistivity imaging has been proved to be well suited to produce images of subsurface conditionsbecause of the ability of the technique for detecting resistive features and discriminating subtle resistivity ...
Comparison Of Distributed Versus Lumped Hydrologic Simulation Models Using Stationary And Moving Storm Events Applied To Small Synthetic Rectangular Basins And An Actual Watershed Basin
(Civil & Environmental Engineering, 2008-04-22)
The purpose of this investigation is to compare simulations using several artificial rectangular basins and a real drainage basin for distributed and lumped hydrologic models via results obtained with the U.S. Geological ...
Building Pressure Tests Of Fiber-reinforced Foam-based Lightweight Concrete Precast Wall Panels
(Civil & Environmental Engineering, 2008-09-17)
Instrumentation and procedures for building pressure tests were designed as a
means of providing new wind pressure test methods for full-scale building models.
Fiber-reinforced foam-based lightweight concrete precast ...
Dynamic Properties Of Compacted Soils Using Resonant Column With Self-contained Bender Elements
(Civil & Environmental Engineering, 2008-08-08)
A comprehensive series of resonant column and bender elements tests were simultaneously performed in the developed RC/BE apparatus. RC/BE tests were conducted on compacted specimens of poorly graded sand (SP) and high ...
Modeling Unsaturated Soil Response Under Suction-controlled Multi-axial Stress States
(Civil & Environmental Engineering, 2008-04-22)
In this research work, a novel suction-controlled true triaxial testing apparatus has been developed to test 3-in (7.5-cm) side, cubical specimens of unsaturated soil under controlled-suction states for a wide range of ...
Deep Mixing Technology For Mitigation Of Swell-shrink Behavior Of Expansive Soils Of Moderate To Deep Active Depths
(Civil & Environmental Engineering, 2008-04-22)
Expansive soils are well known for their cyclic shrink-swell behavior due to seasonal related moisture changes. These cyclic movements of expansive soils are due to physico-chemical changes at particle level that are ...
