Long Term Performance Monitoring of Shallow Slope Stabilization Utilizing Recycled Plastic Pins
(2019-05-14)Shallow slope failures are prevalent within the North Texas region. As highway slopes are underlain with high plastic clayey soils that experience cyclic shrinking and swelling, the soils shear strength generally decreases ... -
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. ... -
LRFD Pullout Resistance Factor Calibration For Soil Nails Incorporating Survival Analysis And PLAXIS 2D
(Civil & Environmental Engineering, 2013-10-23)The use of soil nail walls (SNWs) in the United States has increased since their introduction in the mid-1970's, to where currently the analysis, design and construction are commonly performed (Lazarte, 2011). These SNW ... -
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 ... -
MEDIUM-RANGE ENSEMBLE PRECIPITATION AND STREAMFLOW FORECASTING FOR THE UPPER TRINITY RIVER BASIN IN TEXAS VIA THE NWS HYDROLOGIC ENSEMBLE FORECAST SERVICE
(2015-12-08)Compared to forecasts of short-term precipitation accumulations (daily or shorter) at lead times larger than a few days, those of longer-term accumulations (3-daily or longer) are significantly more skillful owing to the ... -
MERGING RADAR-ONLY QPE AND RAIN GAUGE DATA VIA CONDITIONAL BIAS-PENALIZED OPTIMAL ESTIMATION
(2015-12-08)A new technique for merging radar precipitation estimates and rain gauge data is developed and evaluated to improve multisensor quantitative precipitation estimation (QPE). Various types of linear and nonlinear techniques ... -
Modeling Studies To Assess Long Term Settlement Of Light Weight Aggregate Embankment
(Civil & Environmental Engineering, 2011-03-03)Expanded clay and shale (ECS) is a low weight material derived from clay and shale, and has been used in large quantities throughout the world. Very few studies have been performed to investigate the behavior of ECS and ... -
A New Technique For The Estimation Of The Elastic Moduli Of Pavement Layers From Light Weight Deflectometer Data
