Evaluation of AIMS-II and Micro-Deval for Friction Characteristics of Aggregates
(2015-05-08)
There is a need for a rapid quantitative way to evaluate the quality of aggregate friction properties for use in an asphalt surface (wearing) course. Aggregates that are resistant to polishing and capable of retaining their ...
Evaluation of an Algal Turf Scrubber™ (ATS) Approach for the Remediation of Perfluoroalkyl Substances (PFAS)
(2019-04-17)
Per- and polyfluoroalkyl substances are a large group of synthetic organic chemicals ubiquitous and persistent in the environment due to their fluorinated alkyl chains. Existing methods for remediation of mixtures of PFAS ...
Evaluation of Anionic Polyacrylamide as an Erosion Control Measure Using Intermediate-Scale Experimental Procedures
(2009-05-06)
The United States Environmental Protection Agency (EPA) has been working to establish stricter guidelines and limitations pertaining to stormwater and the various pollutants transported by runoff. This transport is primarily ...
Evaluation of Critical and Essential Concrete Highway Bridges in a Moderate Seismic Hazard
(2014-01-21)
The task of this thesis is to determine if the response of critical and essential bridges designed using the AASHTO LRFD Bridge Design Specifications would meet performance requirements when subjected to the moderate seismic ...
Evaluation of Driver Assistive Truck Platooning on Traffic Flow
(2015-07-21)
Interest in driver assistive truck platooning (DATP) through the application of coordinated adaptive cruise control in the freight trucking industry is on the rise due to its expected benefits on the roadway. To investigate ...
Evaluation of Early-Age Cracking Sensitivity in Bridge Deck Concrete
(2008-12-15)
Early-age cracking is a problem in bridge deck concrete as it can have several detrimental effects on long-term behavior and durability. The primary objective of this project was to evaluate the early-age cracking tendency ...
Evaluation of Erosion and Sediment Control Best Management Practices: Use of Silt Fence Tieback Systems and Anionic Polyacrylamide on Highway Construction Sites
(2007-08-15)
Every year the construction process exposes millions of acres of earth to the elements of wind, rain, and snow. This greatly increases the potential for erosion; therefore, the need for efficient erosion and sediment ...
Evaluation of Erosion Control Practices Under Large-Scale Rainfall Simulation Following ASTM D6459 Standard Test Methods
(2020-05-12)
Land development and construction activities remove vegetative cover, exposing bare soil to the erosive forces of rainfall. Stormwater causes dislodgement of soil particles through splash, sheet, and rill erosion, resulting ...
Evaluation of HDPE and PVC Pipes Used for Cross-drains in Highway Construction
(2011-04-06)
The Federal Highway Administration (FHWA) passed regulations mandating that equal consideration be given to the specification of plastic pipe materials if they were judged to be equally acceptable on the basis of engineering ...
Evaluation of Hydromulches as an Erosion Control Measure Using Intermediate-Scale Experiments
(2010-05-20)
Discharge of sediment-laden stormwater from active construction sites, such as highway construction projects, is a growing concern in the construction industry (Zech et al. 2007, 2008). The United States Environmental ...
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 ...
Evaluation of Inlet Protection Practices (IPPs) Using Large-Scale Testing Techniques
(2014-11-24)
Most roadway construction efforts disturb existing vegetation thereby exposing bare soil to environmental variables that cause erosion. Soil eroded during storm events is conveyed by stormwater runoff and may become ...
Evaluation of Laboratory Cracking Tests Related to Top-Down Cracking in Asphalt Pavements
(2016-12-09)
Top-down cracking (TDC) is now recognized as a prominent mode of failure in asphalt pavements. There has been much research conducted to characterize the failure mechanisms of TDC but there are still large gaps of knowledge ...
Evaluation of Lightweight Aggregate Concrete For Precast, Prestressed Driven Piles
(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 Load Tests for Driven Piles for the Alabama Department of Transportation
(2007-05-15)
A study was carried out to evaluate load testing methods for driven piles for the Alabama Department of Transportation. Dynamic and static load test data were assembled to form the database used in this study. The field ...
Evaluation of Methods to Assess the Strength of Soil Cement Base
(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 ...
Evaluation of New Technologies for Use in Warm Mix Asphalt
(2006-08-15)
Several new processes have been developed with the goal of reducing the mixing and compaction temperatures of hot mix asphalt without sacrificing the quality of the resulting pavement. Three potential Warm Mix Asphalt ...
Evaluation of Non-Solvent Methods to Characterize Reclaimed Asphalt Pavement Binder
(2011-08-17)
Increases in material costs have led many agencies to consider allowing higher percentages of reclaimed asphalt pavement (RAP) in asphalt mixes. However, as RAP percentages increase, the stiffness of the overall mix is ...
