Estimation Of Optimum Compaction Level For Bioreactor Landfill Operation
(Civil & Environmental Engineering, 2014-12)
The effect of compaction on the degradation of MSW is important for the successful operation of bioreactor landfill. It has been a general tendency to compact working face solid waste as much as possible to gain more space. ...
Enhanced Shrinkage Characterization of Clayey Soils
(2015-11-30)
Surficial slope failure is a common problem experienced by most of the compacted earth dams in Texas and several other southern states in USA as a result of desiccation or shrinkage induced cracking of the surficial soils. ...
Comprehensive neural network forecasting system for ground level ozone in multiple regions
(2015-12-07)
A comprehensive neural network daily maximum 8 hour-ozone forecasting model was developed based on five years of data (2010-2014) collected from 50 monitoring sites from the Dallas Fort Worth, Houston-Galveston-Brazoria, ...
Strength And Stiffness Characteristics Of Lime Stabilized Soil In A Flexible Pavement Design
(Civil & Environmental Engineering, 2014-07-14)
Lime treatment has proven to be a useful tool for stabilizing expansive soils. Expansive soils cause major damage to flexible and rigid pavements every year, since seasonal changes in soil moisture creates cyclical changes ...
Comparison Of Prestressed Concrete Girders With Debonded Strands And Harped Strands
(Civil & Environmental Engineering, 2014-07-14)
TxDOT standards follow a design that uses depressed strands for the prestressed concrete I-Girders. A new design criteria using debonded strands for prestressed concrete girders that is widely used in Europe is being ...
Comparison Of Deflection Measurement Methods Of Large Diameter Steel Pipes With Control Low Strength Material
(Civil & Environmental Engineering, 2014-07-14)
This study investigates the structural integrity of large diameter (108 inch) steel pipes with mortar lining embedded with Controlled Low Strength Material (CLSM) during installation. Field tests were carried out in the ...
Long-term Effects Of Synthetic Fibers On Concrete Pipes
(Civil & Environmental Engineering, 2014-07-14)
The studies undertaken by this research were to evaluate the long-term performance and durability of synthetic fiber-reinforced concrete pipes. The target long-term performance is for 9000 hours. Two sets of pipes 8 ft. ...
Characterization and comparison of fresh and landfilled solid waste
(2015-12-07)
The understanding of the characteristics of Municipal Solid Waste (MSW) is very important in planning, designing and operating and/or upgrading the landfill operation system. It is well anticipated that the fresh MSW will ...
ESTIMATION OF REBAR CORROSION IN CONCRETE USING GROUND PENETRATING RADAR
(2015-12-15)
The purpose of this research was to quantitatively relate the amount of rebar corrosion in concrete with the amplitude of electromagnetic waves generated from Ground penetrating radar (GPR). Many studies have been undertaken ...
Experimental Study On Seismic Performance Of Reinforced Concrete Coupling Beams And Rectangular Squat Walls With Innovative Reinforcement Configurations
(2015-12-08)
Reinforced concrete core walls, coupled by diagonally reinforced coupling beams (DCBs), are a very efficient seismic force resisting system for medium- to high-rise buildings. The diagonal reinforcing bars in DCBs are most ...
