A Refined True Triaxial Apparatus For Testing Unsaturated Soils Under Suction-controlled Stress Paths
(Civil & Environmental Engineering, 2009-09-16)
A novel, computer-driven, true triaxial (cubical) apparatus has been developed to test unsaturated soil specimens under suction-controlled multi-axial stress paths that are not achievable in a conventional cylindrical ...
Novel Stabilization Methods For Sulfate And Non-sulfate Soils
(Civil & Environmental Engineering, 2009-09-16)
Expansive soils are commonly found in arid and semi-arid climate zone. These soils typically exhibit moderate to high plasticity, low to moderate strength, and high swell and shrinkage characteristic which in turn result ...
The Effect Of Displacement Control Loading Histories On Genral Connecting Surfaces Using Finite Element Analysis
(Civil & Environmental Engineering, 2009-09-16)
Displacement loading history provided by the AISC Seismic Provision 2002 is commonly used for experimental testing and analytical modeling of beam-to-column steel connection to stimulate the seismic effect. However, the ...
Failure Analysis Of A Mechanically Stabilized Earth (MSE) Wall Using Finite Element Program Plaxis
(Civil & Environmental Engineering, 2009-09-16)
Mechanically Stabilized Earth (MSE) retaining walls have been increasingly used in many federal, state and private projects over the last 20 years. MSE walls are reliable, constructible, and cost effective. However, failure ...
Construction Cost Of Underground Infrastructure
(Civil & Environmental Engineering, 2009-09-16)
Renewal of aging underground infrastructure is a major challenge that municipalities inNorth America face every day. Traditional replacement or renewal of these underground utilitiesuses open-cut excavation methods that ...
Clay Mineral Quantification Using Gravemetric Analysis
(Civil & Environmental Engineering, 2009-09-16)
The current procedure used by the Texas Department of Transportation (TxDOT) to determine the type of stabilizer is based mainly on the Plasticity Index (PI) and the gradation of the soil. This method of stabilization does ...
Measured And Theoretical Response Of Perpetual Pavement Structures
(Civil & Environmental Engineering, 2009-09-16)
The Kansas Perpetual Pavement experiment includes the construction of four pavement sections on the US-75 highway designed according to the perpetual pavement concept. The sections were instrumented with strain gauges and ...
Development Of Brownfield Database Using GIS
(Civil & Environmental Engineering, 2009-09-16)
Brownfields are abandoned, idled or underutilized industrial or commercial sites where expansion or redevelopment is complicated by actual or perceived environmental contamination. Brownfields may be as small as a vacant ...
Applications Of GIS For Mapping And Tracking Underground Infrastructure
(Civil & Environmental Engineering, 2009-09-16)
The main objective of this research is to apply Geographic Information Systems (GIS) for construction and renewal of underground infrastructures. As a first step, a suitability analysis to determine location of existing ...
A Comprehensive Study Of Recycled Concrete Aggregates As A Drainable Base Layer For Pavements
(Civil & Environmental Engineering, 2009-09-16)
The use of recycled materials in construction is becoming increasingly popular due to the shortage of raw materials. Coupled with the environmental concerns surrounding the quarrying of natural minerals, waste materials ...
