Development and Calibration of Safety Performance Functions for Intersections on Rural Divided Highways in Alabama
(2020-07-21)
Although median separated highways provide apparent benefits over undivided highways, sometimes median openings on rural divided highways (RDHs) provide some of the greatest opportunities for frequent and severe crashes ...
Development of a Biennial Review Procedure for Updating Liquidated Damage Rates Used in Construction Contracts
(2007-08-15)
This research effort sought to develop statistically justifiable means for developing a schedule of liquidated damage (LD) rates to be adopted by the Alabama Department of Transportation (ALDOT). The procedure outlined ...
The Development of a Decision Algorithm to Aid in the Selection of Pipe Material for Cross-Drainage Application
(2016-05-05)
The Code of Federal Regulations effectively limited allowable culvert materials to reinforced concrete pipe and corrugated steel pipe on Federal-aided projects. Angered by the exclusion, the plastics industry lobbied ...
Development of a Feeder Route Cyclist Demand Model for Dense Urban Areas
(2012-11-06)
This thesis provides a new way of forecasting bicycle demand in the urban core by using a feeder system approach. It uses a technique of predicting demand at a location for all of the demand feeding into that point. No ...
Development of a Mass Concrete Specification for Use in ALDOT Bridge Construction
(2017-08-29)
Special precautions must be taken when constructing concrete elements designated as mass concrete. These precautions may be satisfied through the formation of a mass concrete specification. Temperature requirements must ...
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 ...
Development of a Non-solvent Based Test Method for Evaluating Reclaimed Asphalt Pavement Mixes
(2005-08-15)
The objectives of this research are twofold. The first is to develop and validate an indirect tension stress relaxation test methodology for assessing asphalt binder properties using compacted hot mix asphalt (HMA) samples. ...
Development of a Performance-Based Mix Design for Porous Friction Course
(2016-08-04)
The development of a performance-based mix design procedure for Porous Friction Course (PFC) will help to mitigate some of the life cycle issues encountered with PFC pavements. PFC pavements are prone to raveling and ...
Development of a Single-Degree-of-Freedom Algorithm for the Analysis of Buried Composite Pipes Subjected to Internal Dynamic Pressure
(2011-12-05)
The overall objective of this research project was to develop a practical engineering methodology for the analysis of underground composite pipes subjected to internal dynamic loading. The need for this analytical methodology ...
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 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 ...
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 ...
Development of composite beam theory and its application in composite and prestressed concrete structures
(2016-05-13)
For some complex structural engineering problems like behavior of sandwich structures and prestressed concrete structures, extensive experimental works and finite element analyses might not be able to help understand the ...
Development of Flexible Pavement Rut Prediction Models from the NCAT Test Track Structural Study Sections Data
(2007-08-15)
This research study was attempted to address two of the most important aspects of mechanistic-empirical (M-E) pavement design. As M-E design continues to advance toward full implementation by state agencies, there is a ...
Development of Guidance for Runoff Coefficient Selection and Modified Rational Unit Hydrograph Method for Hydrologic Design
(2012-05-07)
The rational method is the most widely used method by hydraulic and drainage engineers to estimate design discharges. The runoff coefficient (C) is a key parameter for the rational method. Literature-based C values (Clit) ...
Development of Implementation Guidelines to Assess the Strength of Soil Cement Base in Alabama
(2020-11-16)
