Application of Methods to Characterize VS30 in Alabama

Carcamo, Patricia S. (2022-08-03)

One of the most important characteristics of a soil that is a basis for seismic analysis, is shear wave velocity (VS). VS has proved to be a valuable tool for site response analysis for seismic design since it has the ...

Application of Shrinkage and Swelling Factors on State Highway Construction

Crooks, Alexandria Rhea (2013-04-16)

The objectives of the research were to review the state of practice for roadway related earthwork calculations for the southeastern states, develop a calculation tool for comparing various state earthwork methods, demonstrate ...

Component Level Testing of a Large Area Maintenance Shelter

Koontz, Lloyd (2023-08-04) ETD File Embargoed

Large Area Maintenance Shelters (LAMS) are used by the United States military as temporary shelters for equipment and maintenance. After several LAMS structurally failed in wind speeds within the design parameters, the Air ...

Design of Lateral Support for Non-Integral Wing Walls of Culverts

Lee, Herman III (2017-11-20)

Traditionally, culverts are built with integral wing walls. This style of culvert has shown consistent issues at the joint where the wing wall frames into the culvert bodies due to differential settlement and inadequate ...

Development and Validation of an Inertial Vehicle Barrier Calculator

Norman, Tyler W. (2021-11-11) ETD File Embargoed

The danger of malevolent vehicle penetration attempts at the perimeter of protected facilities is an increasing threat across the globe. Passive, unanchored inertial vehicle barriers rely on their mass and friction with ...

Development of Implementation Guidelines to Assess the Strength of Soil Cement Base in Alabama

Mueller, Emily (2020-11-16)

Soil cement is a mixture of soil, portland cement, and water that forms a strong, durable, frost-resistant pavement base once compacted and cured. Variation among construction practices and concerns of current quality ...

Earth Anchor Loading and Capacity for Temporary Structures Under Wind Load

Matthews, P. Anthony (2024-05-01) ETD File Embargoed

Ground anchors have been used in construction for decades to provide tethering and uplift support to many types of construction and utility operations. Many of the current techniques to evaluate pull out capacity of anchors ...

Effect of hydrologic and hydraulic calculation approaches on pier scour estimates

Castaneda Galvis, Luis Fernando (2023-12-05)

Bridge scour, a phenomenon characterized by the erosion and removal of sediment from the vicinity of bridge foundations, is a significant concern in the fields of civil engineering and infrastructure management. There are ...

Evaluation of Lightweight Aggregate Concrete For Precast, Prestressed Driven Piles

Belk, Neill (2013-05-13)

Driven piles, specifically, precast, prestressed (PCPS) piles are concrete foundation elements used to transmit heavy structural loads and moments to an adequate bearing layer and reduce total settlement. ...

Evaluation of Methods to Assess the Strength of Soil Cement Base

McLaughlin, Justin (2017-07-28)

Soil cement is a mixture of soil, portland cement, and water that, once compacted and cured, forms a strong and durable pavement base. Construction practices and variance among core strength data have led to questions ...

Full Scale Testing of Two Excavations in an Unsaturated Piedmont Residual Soil

Burrage, Richard Jr. (2016-01-06)

Residual soil behavior can be difficult to predict using current geotechnical formulas, because it exhibits properties that are not common to transported soils. These unique properties are mainly influenced by the fabric ...

Implementation of Geosynthetic Reinforced Soil- Integrated Bridge System (GRS-IBS) Technology in Alabama

Stallings, Jeffrey (2020-08-24)

Geosynthetic reinforced soil-integrated bridge systems (GRS-IBS) utilize mechanically stabilized earth (MSE) systems to support single-span bridges. A typical GRS-IBS is made up of three components: the reinforced soil ...

Insitu Measurement of Pavement Distress and Causal Mechanisms in Expansive Soil along Alabama Highway 5

Jackson, Dan (2016-12-07)

Alabama Highway 5 is a farm-to-market road built directly on an expansive clay subgrade. Moisture fluctuations cause the soil to shrink and swell, resulting in severe pavement distress. Laboratory testing has been performed ...

Investigation of Pavement and Subgrade Distress at Alabama Highway 5

Stallings, Elizabeth Grace (2016-08-05)

The primary objectives of this study were to determine the root causes for subgrade failure and associated pavement distress along Alabama Highway 5 in Perry County, Alabama. In order to accomplish these goals photographic, ...

Laboratory and Field Measurements of Moisture Content and Bulk Electrical Conductivity of Subgrade and Base Course Materials

Diekmann, Amy (2023-08-04) ETD File Embargoed

Moisture content can impact the resilient modulus of pavement base course and subgrade layers. Given its influence on the post-inundation resilient moduli of the coastal pavement and base course and subgrade layers, it is ...
