A STUDY ON THE INFLUENCE OF SELECTED GEOGRID INDEX PROPERTIES ON THEIR IN-AGGREGATE PERFORMANCE
Mahmood, Tahsina (2013)Geogrids are polymer-based products which are commonly used to reinforce soil walls, steep slopes and roadway bases. Inclusion of geogrids as aggregate base reinforcement, with proper installation, has been shown to result ... -
Application of Rapid-Setting Belitic Calcium Sulfoaluminate Cements in Pretensioned, Prestressed Concrete
Roswurm, Stephen (2023-05-13)In recent years, urgency for adopting sustainable materials has come to the forefront of the cement and concrete industries. Belitic calcium sulfoaluminate (BCSA) cement is an alternative cement which has a production ... -
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 ... -
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 ... -
Characterization of Rutting in Asphalt Pavements using Laboratory Testing
Rani, Shivani (2019)In asphalt pavements, rutting is one of the main concerns at high in-service temperature, which can occur either through plastic flow or shear in structural layers. Rutting depends on several factors, such as asphalt binder ... -
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 ODOT GUIDELINES FOR THE USE OF GEOGRIDS IN AGGREGATE BASES (FHWA-OK-12-04 2220)
Hatami, Kianoosh; Mahmood Tahsina; Zaman, Musharraf; Ghabchi, Rouzbeh (2012-3)A primary objective of the current study was to help ODOT expand its selection of approved geogrid products for base reinforcement applications by producing measured ata on selected geogrids and a dense-graded base aggregate ... -
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
Ngo, Theresa (2016-05)Bridges supported on deep foundations constitute the conventional and standard construction practice. While deep foundations provide several advantages for bridges with respect to their stability and performance, they also ... -
FEASIBILITY STUDY OF GRS SYSTEMS FOR BRIDGE ABUTMENTS IN OKLAHOMA: INFLUENCE OF FACING AND AGGREGATE FILL ON PERFORMANCE (FHWA-OK-19-09 2262)
Hatami, Kianoosh; Doger, Ridvan; Boutin, Jérome (2020-01)This document reports a study where load-bearing capacity, deformations and construction speed of different GRS abutment models were compared in the laboratory at full scale. Six 8 ft-high, instrumented abutment models ... -
FIELD VERIFICATION OF GEOGRID PROPERTIES FOR BASE COURSE REINFORCEMENT APPLICATIONS (FHWA-OK-13-11 2244)
Hatami, Kianoosh; Mahmood, Tahsina; Pereira-Villarroel, Juan (2013-11)The proposed field study is a continuation of a recently concluded, ODOT-funded project titled: Development of ODOT Guidelines for the Use of Geogrids in Aggregate Bases, which is aimed at addressing the need for improved ... -
Impact of elevated temperatures on soil tensile strength
Salimi, Kwestan (2021-05-14)Tensile strength of unsaturated soils is a critical factor controlling the initiation and propagation of desiccation cracks, which can threaten the structural integrity of natural and man-made earthen structures and slopes. ... -
IMPACT OF MOISTURE CHANGES IN UNSATURATED SOIL ENGINEERING APPLICATIONS
Hassanikhah, Arash (2016-12-16)The mechanical and hydraulic properties of soil above the groundwater table change due to unsaturated conditions. While common, considering soil to be saturated as a simplifying assumption in the design of many important ... -
Influence of Compaction and Quality Control on the Performance of GRS-IBS Bridge Abutments
