The overall objective of this research was to optimize the individual layers of a multilayered airfield pavement to make the pavement more resilient to blast and impact loadings when compared to a baseline rigid pavement. ...

Analysis of Distress Along U.S. 331, Montgomery, AL Between Mile Markers 88.480 and 91.070 

Jannett, Richard (2013-04-29)
This report investigates the cause of asphalt concrete pavement distress along U.S. 331 between mile markers 88.480 and 91.070. The distress consisted of standalone bumpy sections of the asphalt concrete pavement, all less ...

A Benefit/Cost Analysis of Paved Shoulder Installation on High Priority Road Segments on Two-Lane Rural Highways in Alabama 

Ayala, Renee (2008-08-15)
There are currently more than 40,000 deaths a year that occur as the result of motor vehicle traffic accidents, which have been ranked among the leading causes of death for Americans. In addition, a reported 55% of all ...

Comparison of New Technology for Measuring Ride Quality 

Hays, Joshua (2006-12-15)
Ride quality of a pavement is quantified by a statistical index. The statistical index and the profile device used to assess the index are major variables in pavement smoothness. Due to the wide range of these variables ...

Design and Characterization of Cold Recycled Foamed Asphalt Mixtures with High RAP Contents 

Ma, Wangyu (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 ...

Determining the Optimum Compaction Level for Designing Stone Matrix Asphalt Mixtures 

Xie, Hongbin (2006-05-15)
As Stone matrix asphalt (SMA) becomes more widely used in the United States, there is a need to further refine its mix design procedure. Some states have found that 100 gyrations with the Superpave Gyratory Compactor (SGC) ...

Development of a Feeder Route Cyclist Demand Model for Dense Urban Areas 

Scurlock, Kristin (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 Flexible Pavement Rut Prediction Models from the NCAT Test Track Structural Study Sections Data 

Selvaraj, Suresh Iimmanuel (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 ...

Dewatering Rock Crushing Fines Using Geotextile Tubes 

Myers, William, Jr. (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 ...

Drained Residual Strength of Expansive Soils Causing Pavement Distress along Alabama Highway 5 

Kennedy, Lydia (2019-11-15)
A segment of Alabama Highway 5 (AL-5) located in Perry County, Alabama has been experiencing severe pavement distress that is mostly caused by the behavior of soil beneath the roadway. AL-5 is a farm-to-market road that ...

Early Characterization and Performance of a Flexible Thick Lift Pavement 

McCarty, Caroline (2019-12-05)
The South Carolina Department of Transportation (SCDOT) has recently been experimenting with thick lift paving to increase construction speed and facilitate faster access to traffic. However, there has been limited research ...

Early Characterization and Performance of Flexible Pavements Utilizing Asphalt Additives 

Foshee, Megan (2022-04-25)
Asphalt additives have been utilized for years to modify the performance of flexible pavements. They have the potential to lead to long-lasting and sustainable asphalt pavements. In recent years, several new categories of ...

Effect of Mixture Properties and Testing Protocol on Moisture Susceptibility of Asphalt Mixtures 

Leatherman, Kristoffer (2012-07-25)
While cracking and rutting are the most prevalent distresses for asphalt mixtures, moisture susceptibility of asphalt mixtures which can lead to distresses such as raveling, loss of adhesion, and stripping is a commonly ...

Effectiveness of pavement preservation treatments on the structural health of the pavement 

Rahman, Md Towhid Ur (2019-11-25)
Pavement preservation treatments are widely applied for surface condition restoration based on different purposes and extent of surface damage. No significant study has been executed on if the preservation treatments provide ...

Evaluating the Contribution of Asphalt Binder from Recycled Asphalt Shingles in Asphalt Concrete 

Farris, Thomas David (2016-05-04)
The use of Recycled Asphalt Shingles (RAS) to replace a portion of the virgin asphalt binder in asphalt mixtures has been increasing over the past several years due to environmental and economic motivations. Yet, since ...

Evaluation of a Solvent-less Method for Estimating Asphalt Binder Properties of Recycled Asphalt Pavement 

Turner, Pamela (2013-04-29)
Increasing amounts of Reclaimed Asphalt Pavement (RAP) are being used in response to the rising costs of asphalt materials. The asphalt paving industry currently lacks a method for characterizing the properties of the ...
