A Critical State Approach to the Mechanical Behavior of Early-Age Cemented Paste Backfill
Ghorbanpour, Amin B. (2019-12-16)Low plasticity to non-plastic mine tailings are typically transported to a storage area through pipelines in form of slurry or thickened tailings. The main concern with such tailings deposits is the possibility of liquefaction ... -
A NEW GEOTHERMAL BRIDGE DE-ICING SYSTEM WITH ATTACHED HYDRONIC HEATING LOOPS: FIELD TESTS, NUMERICAL MODELING, AND ECONOMIC ASSESSMENT
Habibzadeh Bigdarvish, Omid; 0000-0002-7577-1892 (2021-08-10)Each year, ice and snow adversely impact U.S. transportation infrastructure during the cold season, causing an extensive impact on the U.S. economy. Bridges are key elements in the transportation network and the most ... -
CHEMICAL STABILIZATION OF EXPANSIVE SOILS USING LIQUID IONIC SOIL STABILIZERS (LISS)
He, Shi; 0000-0002-6056-409X (2019-08-12)Traditional soil stabilizers such as lime and cement are widely used to reduce swell and shrinkage behavior and enhance strength properties of expansive soils through the formation of cementitious products. However, the ... -
Development And Validation Of TDR Based Sensors For Thermal Conductivity And Soil Suction Measurements
Zhang, NanSimultaneous measurement of soil thermal conductivity, moisture content, dry density and soil suction is a challenging issue and very important to the design of geothermal related structures such as geothermal energy piles ... -
Discrete Element Modeling Of Geogrid Reinforced Granular Media
Pradhan, AsheeshGeogrids have proven to be economical solution in improving ground conditions for construction in foundations, retaining walls, railway tracks, and pavements. Hence researchers have started studying the geogrid reinforcement ... -
EVALUATION OF MODEL UNCERTAINTIES IN LRFD CALIBRATION PROCESS OF DRILLED SHAFT AXIAL DESIGN
Hasan, Mohammad Rakib (2019-08-12)The Federal Highway Administration (FHWA) released a policy in 2000 that required all new federally funded bridges to be designed using the AASHTO LRFD specifications by October 2007. The transition from ASD to LRFD posed ... -
EVALUATION OF STRUCTURAL CAPACITY OF EPOXY-COATED CONCRETE PIPES AND ITS INTERACTION WITH SOIL
Riahi, Elmira; 0000-0002-0665-6663 (2016-08-18)Rehabilitation of concrete structures by using synthetic resins such as epoxy is increasing worldwide. Understanding the structural behavior of the resultant composite structure and the interaction between the coating and ... -
Laboratory tests and numerical model of geothermally heated bridge deck with attached hydronic loop
Li, Teng; 0000-0002-0748-2546 (2020-12-17)An accumulation of ice and snow on pavement slabs and bridge decks always adversely impacts driving conditions and results in motorist accidents. The use of the more popular deicing methods, including plowing, salting, and ... -
MECHANICAL RESPONSE OF CHEMICALLY TREATED SULFATE-RICH CLAY UNDER MULTIPLE TRIAXIAL STRESS PATH
Asghariastaneh, Azadeh; 0000-0002-6354-6743 (2021-07-21)Expansive clayey soils, which are abundant in arid and semi-arid areas, including the state of Texas, can lead to excessive distress in pavements, foundations, embankments, earth retaining systems and other civil infrastructure ... -
