Analysis of Slope Failures Along Alabama Highways
(2018-08-20)
Slope stability management systems (SSMSs) have been developed by multiple state transportation agencies to assess landslides adjacent to highways—aiding in the effective allocation of resources for slope and/or roadway ...
Relationship between Asphalt Binder Fatigue Properties and Mixture Fatigue Performance
(2018-07-25)
Fatigue cracking caused by repeated traffic loading is one of the major distresses in asphalt pavement. To control fatigue cracking, the current Superpave binder specification requires a maximum value of 5,000 kPa for the ...
Design and Characterization of Cold Recycled Foamed Asphalt Mixtures with High RAP Contents
(2018-04-24)
Cold recycling with foamed asphalt has been considered as a sustainable pavement rehabilitation technology. Although different mix design methods have been proposed, there is no widely accepted standard. The effects of ...
Development of an Analytical Method for Quantification of Endocrine-Disrupting Phytoestrogenic Compounds in Estuarine Environment Using UHPLC-MS/MS
(2018-04-27)
Endocrine disrupting compounds (EDCs) are nearly ubiquitous in the daily lives of individuals around the globe. Phytoestrogenic polyphenols (PEPPs, also known as phytoestrogens) represent a subgroup of EDCs. They are ...
Development of Breakdown Probability Models for Rural Freeway Work Zones Using Field Data and Simulation
(2018-04-27)
The current state of the National Highway System often necessitates that agencies interrupt normal traffic operations for maintenance and capacity improvements. With nearly 9 million lane-miles of public roadway and an ...
Torsional Resistance of Drilled Shaft Foundations
(2018-07-30)
Drilled shaft foundations are commonly selected by public transportation agencies to support mast-arm traffic sign and signal pole structures. Those inverted L-shaped structures are subjected to lateral and torsional loading ...
Development of a Means to Calculate Project-Specific Liquidated Damages on ALDOT Projects Exceeding $20 Million
(2018-11-07)
This research effort sought to create a justifiable means for developing a project-specific liquidated damages (LD) calculation method for high value projects to be adopted by the Alabama Department of Transportation ...
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 ...
Degradation of Metronidazole by carboxymethyl cellulose stabilized iron sulfide nanoparticles in water and soil phases
(2018-05-16)
The removal of Metronidazole (MNZ) from water and soil phases by iron sulfide (FeS) nanoparticles was investigated. From the results, for the batch test, 10 mg/L MNZ in the solution can be fully removed by the 350 mg/L FeS ...
Fabric Structure Strength and Structural Integrity of Large Area Maintenance Shelters (LAMS)
(2018-12-19)
Large Area Maintenance Shelters (LAMSs) are deployed worldwide by the United States Air Force. The U.S. Air Force uses LAMSs as storage facilities and hangars for vehicles and aircrafts alike. The inherent low weight and ...
