Advanced Computing Techniques in Structural Evaluation of Flexible Pavements Using the Falling Weight Deflectometer

Leiva-Villacorta, Fabricio (2012-07-25)

The use of nondestructive deflection testing has become an integral part of the structural evaluation and rehabilitation process of pavements in recent years. The falling weight deflectometer (FWD) is commonly used to ...

Calibration of Fatigue Transfer Functions for Mechanistic-Empirical Flexible Pavement Design

Priest, Angela (2005-12-15)

As agencies continue to adopt mechanistic-empirical (M-E) pavement design, the need for locally calibrated transfer functions will continue to increase. Transfer functions are the critical link from mechanical pavement ...

Development of a Non-solvent Based Test Method for Evaluating Reclaimed Asphalt Pavement Mixes

Carter, Alan (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. ...

Integration of GIS into Pavement Management Systems for Low Volume County Roads

Grass, David (2007-05-15)

Geographic Information Systems (GIS) have often been used for highway pavement management (PM), but rarely for low volume county roadway systems. Methods for implementing GIS as a useful tool for county engineers in ...

Investigation of Permeable Asphalt Treated Bases in Alabama

Wielinski, Jason (2007-05-15)

The Alabama Department of Transportation currently uses a permeable asphalt treated base (PATB) course layer consisting of an AASHTO number 57 aggregate gradation with 2.0% to 2.5% asphalt content. The current mixture ...

Local Calibration of the MEPDG Using Test Track Data

Guo, Xiaolong (2013-11-08)

The Mechanistic-empirical Pavement Design Guide (MEPDG), now known as AASHTOWare Pavement ME Design, is a state-of-art mechanistic-empirical design method. It has been adopted by the American Association of State Highway ...

Physical and Structural Characterization of Sustainable Asphalt Pavement Sections at the NCAT Test Track

Vargas-Nordcbeck, Adriana (2012-07-25)

A sustainable pavement can be defined as a safe, efficient and environmentally friendly pavement that meets today’s transportation needs without jeopardizing the ability to meet such needs in the future. Recent advances ...

A Statistical Analysis of Georgia's HMA Quality Assurance Proccess

Willis, James (2005-12-15)

In the recent years, there has been a push towards allowing contractors to use their own test results in the quality assurance process of Departments of Transportation (DOTs). While this movement saves the states money ...

Structural Characterization of Recycled Materials at the NCAT Test Track

Diaz Sanchez, Miguel Angel (2019-11-22)

The functional and structural performance of two pavement recycling techniques: Cold Central-Plant Recycling (CCPR) and Cement Treated Base (CTB) from a Full Depth Reclamation (FDR) process, were evaluated under accelerated ...

A Study of the Thermal Interactions of Sustainable Asphalt Concrete Pavements

Diaz Sanchez, Miguel Angel (2013-12-04)

A study of the thermal interactions of select sustainable technologies, such as reclaimed asphalt pavements (RAP), recycled asphalt shingles (RAS), ground tire rubber (GTR), and foamed asphalt in cold recycled materials ...
