Stability of Timber Bridges Subject to Scour
(2012-07-25)
Because scour is responsible for most disastrous bridge failures, bridge scour monitoring is necessary for the safety of public roads. While much attention is paid to the amount of bridge scour at a foundation, the ...
State of the Practice of Long Distance and Intercity Travel Modeling in US Metropolitan Planning Organizations and State Departments of Transportation
(2019-04-23)
Long distance and intercity travel represent a small percentage of total trips in the U.S., yet they represent a large percentage of total VMT. Long distance trips represent an important travel market with over $317 billion ...
Static Load Testing of a Damaged, Continuous Prestressed Concrete Bridge
(2009-05-15)
Shortly after the completion of interstate highway I-565 in Huntsville, Alabama, cracks were discovered in the continuous end of many of the prestressed concrete bulb-tee girders. Alabama Department of Transportation ...
Static Resistance Functions for Unbonded Retrofit Unreinforced Concrete Masonry Walls with Plate Connection for Blast Design Applications
(2013-07-10)
Over the past two decades the use of explosives to attack both commercial and government buildings has increased. A substantial amount of research has been conducted to be able to protect not only the occupants but the ...
A Statistical Analysis of Georgia's HMA Quality Assurance Proccess
(2005-12-15)
In the recent years, there has been a push towards allowing contractors to use their own test results in the quality assurance process of Departments of Transportation (DOTs). While this movement saves the states money ...
Statistical Model Development for Estimating Bicycle Rack Usage at Auburn University
(2011-05-17)
The objective of this research was to develop and evaluate statistical models to estimate bicycle rack usage for a university campus environment. An analysis was conducted on bicycle rack usage data, collected in 2008, ...
A Stochastic Three-Dimensional Cost Estimation System for Hot Mix Asphalt in the State of Alabama
(2018-04-30)
Asphalt is one of the most critical commodities for the American infrastructure. It is used as a paving material on the majority of the U.S. roadways. The National Asphalt Paving Association (NAPA) estimates that about 94 ...
Streamflow Signature Analysis of Long-Term Effects of Urbanization on Hydrologic Alteration in the Southeastern United States
(2018-12-19)
Urbanization in the southeastern United States has risen exponentially over the past few decades. This increase causes runoff to have a greater surface flow, a smaller interflow, and sometimes a reduced baseflow by changing ...
Strength Assessment of Soil Cement
(2013-01-07)
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 ...
Strength Assessment of Soil Cement
(2016-12-07)
Soil cement is a mixture of soil, portland cement, and water that is compacted and cured to form a pavement base. Due to construction practices and variances in core strengths, questions have arisen concerning quality ...
Strength Assessment of Soil Cement Base in Alabama
(2020-07-30)
Soil cement is a mixture of soil, portland cement, and water that is compacted and cured to form a strong, durable pavement base. Variances among construction practices and core strength data have led to questions concerning ...
Structural Characterization of Recycled Materials at the NCAT Test Track
(2019-11-22)
The functional and structural performance of two pavement recycling techniques: Cold Central-Plant Recycling (CCPR) and Cement Treated Base (CTB) from a Full Depth Reclamation (FDR) process, were evaluated under accelerated ...
Structural Performance of Self-Consolidating Concrete in AASHTO Type I Prestressed Girders
(2008-08-15)
As part of a larger investigation sponsored by the Alabama Department of Transportation (ALDOT) into the use of self-consolidating concrete (SCC) in bridge girders, this thesis documents a structural investigation of SCC ...
A Study of Differences in Severity among Crash Types in Work Zones and between Work Zone and Non-Work Zone Crashes in Alabama
(2018-07-23)
Highway work zones have become a hazardous place for both construction workers and roadway users due to the increasing risk caused by maintaining and reconstructing roadways. Both the number of crashes and fatalities in ...
A Study of the Effects of Pavement Widening, Rumble Strips, and Rumble Stripes on Rural Highways in Alabama
(2015-05-05)
Run-off-road (ROR) crashes are usually severe and account for a significant amount of highway
fatalities. It is estimated that more than 50% of the fatal crashes in the United States and in
Alabama are ROR crashes. Rural ...
A Study of the Thermal Interactions of Sustainable Asphalt Concrete Pavements
(2013-12-04)
A study of the thermal interactions of select sustainable technologies, such as reclaimed asphalt pavements (RAP), recycled asphalt shingles (RAS), ground tire rubber (GTR), and foamed asphalt in cold recycled materials ...
System Reliability Model for Long Span Arch Bridges
(2018-05-17)
Every structural system consists of elements with certain dependencies between each other. Current design codes do not account for these interactions and they provide provisions only for particular components. Thus, the ...
Target Reliability Analysis for Structures
(2015-01-06)
Structural performance depends on load and resistance parameters, in particular magnitude and frequency of load components and their combinations, strength of materials, modulus of elasticity, dimensions, rate of deterioration, ...
A Technology for Enhanced Control of Erosion, Sediment and Metal Leaching at Disturbed Land Using Polyacrylamide and Magnetite Nanoparticles
