Evaluation of allowable stresses for high strength concrete prestressed bridge girders
(Texas A&M University, 2003)
High strength concrete (HSC) is regularly used for prestressed bridge girders in Texas and other states. The American Concrete Institute (ACI) Committee 363 (1997) defines HSC as concrete with a compressive strength ...
Accelerated quantification of critical parameters for predicting the service life and life cycle costs of chloride-laden reinforced concrete structures
(Texas A&M University, 2003)
The use of corrosion resistant steels (instead of conventional carbon steels) and/or high performance concrete can increase the overall service life and can reduce the life cycle cost (LCC) of reinforced concrete (RC) ...
A simplified formulation for moisture diffusion through partly saturated clays
(Texas A&M University, 2003)
Civil works constructed of high plasticity clays can be dramatically affected by strength loss in spite of careful compaction and moisture control. Highway embankments and retaining walls are good example of affected ...
Adaptive prediction of pavement performance
(Texas A&M University, 2002)
A Visual Basic 6.0[TM] computer program for adjusting family performance curves in making reasonable predictions of individual pavement section performance has been developed under this study. The methodology formulated ...
Predicting the behavior of nearshore feeder berms in the vicinity of Morro Bay, California
(Texas A&M University, 2000)
Being able to predict the final disposition of dredged material mounds is important in the planning of dredging operations. A computerized mathematical model, based on the sediment movement equations of Ackers and White, ...
The feasibility of electrophoretic repair of impoundment leaks
(Texas A&M University, 2002)
Geomembrane liners installed in surface industrial impoundment may be impaired due to physical damage, improper installation, abnormal materials, construction cracks, or human mistakes during operation. Conventional repair ...
The effects of vegetation parameter aggregation on modeled evapotranspiration
(Texas A&M University, 2001)
The effect of the scale of vegetation parameter aggregation on modeled evapotranspiration pattern and rate is explored. Vegetation biomass, height and fractional coverage per model grid cell were the vegetation parameters ...
Identification and characterization of agent for reductive dechlorination in mixtures of ferrous iron and Portland cement
(Texas A&M University, 2001)
Degradative Solidification/Stabilization (DS/S) is a modification of conventional S/S in which organic pollutants are destroyed while inorganic pollutants are immobilized. Fe(II) is used in Fe(II)-based DS/S as a reductant ...
Tool developing of MRR strategy selection
(Texas A&M University, 2001)
Better decision-making processes, guidelines, and tools to select MRR (maintenance, rehabilitation, and reconstruction) strategies are very necessary for SHAs (state highway agencies) to evaluate the effectiveness of their ...
Validation of the new mixture design and testing protocol for lime stabilization
(Texas A&M University, 2001)
The Mississippi Department of Transportation (MDOT) has used hydrated lime for over 30 years to stabilize subgrades. In 1998 a project was initiated to assess material properties and performance derived from lime treated ...
