Application of Traffic Speed Deflectometer and AI-Based Models for Structural Calibration and Pavement Management Enhancement
Mendez Larrain, Matias M. (2023)Currently, different methods are used for the evaluation of pavement conditions including the surface, base, subbase, and subgrade. Among these, Falling Weight Deflectometer (FWD) and/or Fast Falling Weight Deflectometer ... -
APPLIED APPROACH SLAB SETTLEMENT RESEARCH, DESIGN/CONSTRUCTION (FHWA-OK-13-09 2227)
Miller, Gerald; Hatami, Kianoosh; Cerato, Amy; Obsorne, Colin (2013-8)Approach embankment settlement is a pervasive problem in Oklahoma and many other states. The bump and/or abrupt slope change poses a danger to traffic and can cause increased dynamic loads on the bridge. Frequent and costly ... -
A bounding surface model for cyclic response of cement-improved clays
Quiroga, Allison (2018-05-11)The use of chemical stabilization of soft soils to achieve increased strength and decreased compressibility for subgrade and site improvement applications is a well-documented and accepted practice in geotechnical engineering. ... -
Calibration of a Handheld X-Ray Fluorescence Device to Detect Chemical Stabilizers in Soil Subgrades
Van Hemelryck, Theo (2018-12)Chemically stabilized subgrades increase the overall quality of pavements compared to non-treated subgrades. Currently, there is no efficient way to detect chemical stabilizers (CS) in pavement subgrades. Generally, only ... -
Characterization of Cement-Stabilized Clay Using Experimental and Analytical Techniques
Tabet, Wassim (2015-12)Problematic soils such as soft, compressible, collapsible, or expansive soils are widespread throughout the world and are often becoming unavoidable due to the continuous expansion of societies. Soil improvement techniques ... -
Construction and Load Testing of Two Field-Scale Model GRS Bridge Abutments
Falcon, Kirby (2021-12)Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) is an alternative bridge construction technique to conventional, deep-foundation bridge abutments. GRS-IBS has shown signs of expedited construction speeds ... -
Development of Non-Proprietary Ultra-High-Performance Concrete Mix Designs
McDaniel, Amy (2017-12)Ultra-High-Performance Concrete (UHPC) is defined by the Federal Highway Administration (FHWA) as having a compressive strength of 21.7 ksi (kilo-pounds per square inch), a post-cracking tensile strength 0.72 ksi, and high ... -
Development of Soil-Pile Interaction Models in Improved Soils Using Centrifuge Test Data and System Identification Methods
Soltani, Hoda (2016-05-13)Documented distresses in pile foundations in soft soils during past earthquakes have shown that piles founded in soft soils undergo large lateral deformations during seismic loading. Improving the soil surrounding the piles ... -
The Effects of Evaporation and Capillary Forces on Fluid Motion, Solute Transport, and Water Content From the Grain Scale to the Continuum Scale in Unsaturated Porous Media
Adegbule, Aderonke (2019)This work aimed to explore how fluid motion, solute transport, and water content are influenced by evaporation and capillary forces in unsaturated porous media, across a range of scales. Experiments were conducted from the ... -
EFFICACY OF ROAD BOND AND CONDOR AS SOIL STABILIZERS (FHWA-OK-13-06 2242)
Miller, Gerald; Bounds, Tommy (2013-8)The Oklahoma Department of Transportation (ODOT) uses lime-based stabilizers including quick lime, hydrated lime, Class C fly ash (CFA) and cement kiln dust (CKD) to increase bearing capacity of fine-grained subgrade soils ... -
EVALUATION AND FIELD VERIFICATION OF STRENGTH AND STRUCTURAL IMPROVEMENT OF CHEMICALLY STABILIZED SUBGRADE SOIL (FHWA-OK-08-01 2195)
Snethen, Donald R.; Miller, Gerald; Cerato, Amy (20018-7)Often subgrade soils exhibit properties, particularly strength and/or volume change properties that limit their performance as a support element for pavements. Typical problems include shrink-swell, settlement, collapse, ... -
Evaluation of Durability and Corrosion Behavior of Ultra-High Performance Concrete for use in Bridge Connections and Repair
Leggs, Maranda (2019-08-01)Ultra-high performance concrete (UHPC) is one of the new, cutting edge concepts in the world of concrete. Boasting significantly higher compressive and tensile strengths, longer service life, and significantly increased ... -
EVALUATION OF STORMWATER TREATMENT BY VARIOUS REACTIVE MEDIA FOR BIORETENTION CELL DESIGN CONSIDERATIONS
Nguyen, Derrick (2018-05)Bioretention cells (BRC) can be effective at filtering particulate pollutants from stormwater runoff, but substantial removal of the dissolved pollutant fraction is challenging. Various reactive treatment media for BRCs ... -
Feasibility of Blast Furnace Slag for Stabilizing Sulfate-Bearing Soil
Mantilla Prada, Daivy Jhonander (2023-12-15)Calcium-based stabilizers are frequently used by The Oklahoma Department of Transportation (ODOT) to enhance the strength and reduce the swelling potential of fine-grained soils. However, these stabilizers can lead to ... -
Feasibility Study of Geosynthetic Reinforced Soil Integrated Bridge Systems (GRS-IBS) in Oklahoma
