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, ...
Development of an Inhibitor Resistant Genomic Assay for Environmental Samples
(2014-07-24)
Rapid identification and quantification of bacteria is beneficial for the environmental monitoring, such as water quality and site clean-up. However, existing bacteria quantification methods, such as colony counting or ...
Effect of Core Geometry and Size on Concrete Compressive Strength
(2014-11-06)
To evaluate the in-place concrete strength for acceptance for a structural member with potentially substandard strength, the compressive strength of cores may be required for assessment. Depending on the geometry and size ...
Evaluation of In-Place Concrete Strength by Core Testing
(2014-12-16)
When the average compressive strength of molded cylinder specimens do not meet the minimum required strength for a batch of concrete, testing must be performed on the in-place concrete to evaluate its strength. There are ...
Exploration of Crash Severity and Location in Work Zone-Related Crashes in Alabama
(2015-01-07)
Work zones are necessary for maintenance and improvement of highways, but they also present opportunities for crashes that might not occur under normal driving conditions. From 2006-2011, 3,192 crashes resulted in some ...
Measuring and modeling the impact of roadway runoff on a headwater tributary of the Cahaba River
(2015-07-24)
Stormwater runoff from highways has been a relevant focus of study both in terms of its characterization during construction phases as well as during the operational years. Highways have been thought to have adverse impacts ...
A Review of the Alabama Department of Transportation’s Policies and Procedures for Life-Cycle Cost Analysis for Pavement Type Selection
(2015-05-11)
This thesis examines the process of life-cycle cost analysis for pavement type selection and gives specific consideration to the policies and procedures used by the Alabama Department of Transportation as of June 2013. ...
Application and Evaluation of WEPP in a Forested Watershed with Perennial Streams
(2010-01-06)
Forests generally have low erosion rates unless they are disturbed by harvesting operations or road construction. These common disturbances typically cause increase in the sediment yield which is reduced after vegetation ...
Dewatering Rock Crushing Fines Using Geotextile Tubes
(2010-01-06)
A study on dewatering rock crushing fines using geotextile tubes was conducted. The laboratory portion included rapid dewatering tests and hanging bag tests to evaluate the dewatering efficiencies of the geotextiles as ...
Alternative Fuels and Their Effects on Portland Cement
(2010-07-19)
The production of portland cement is a complex process involving several materials, complex systems, and temperatures on the order of 1500 °C. Non-renewable fossil fuels such as coal, petroleum coke, and natural gas have ...
