Local Calibration Of Pavement Me And Performance Evaluation Of Pavement Rehabilitation And Preservation Asphalt Overlays In Louisiana, Farzana Moon
LSU Master's Theses
Asphalt overlays can be categorized as pavement rehabilitation structural overlays or pavement preservation overlays in terms of the thickness and timing of maintenance activities. Pavement rehabilitation overlay contributes to the structural enhancement of pavements and pavement preservation overlays generally provide functional improvement to an existing pavement. In recent times, the pavement design approach employed by the Louisiana Department of Transportation and Development (LADOTD) has been transitioning from the 1993 AASHTO design procedure to a locally calibrated Pavement ME method. The AASHTOWare Pavement ME (Mechanistic-Empirical) design procedure is considered the modern approach to pavement design. Significant updates have been introduced in …
Variability In The Hamburg Wheel-Tracking Device (Hwtd) Data And Results, Ilerioluwa S. Giwa
Variability In The Hamburg Wheel-Tracking Device (Hwtd) Data And Results, Ilerioluwa S. Giwa
LSU Master's Theses
Over the years, the Hamburg Wheel-Tracking Test (HWTT) has become one of the most popular devices used for characterizing asphalt mixtures for rutting potential and moisture susceptibility. However, although the HWTT is a reliable standard test for evaluating asphalt mixtures, it is not exempt from variability in the test data and result. Variability in the HWTT test data and results have been majorly attributed to imprecision in the test practice and due to some limitations in the HWT device setup.
The primary goal of this study is to evaluate the variability in the HWTT data and result by investigating a …

Development Of Cracking Resistance Prediction Model Of Long-Term Aged Asphalt Mixtures, Peyman Barghabany
LSU Doctoral Dissertations
With the increasing complexity of asphalt mixture composition, the current volumetric-based Superpave mixture design would not be sufficient to address durability concerns. To address this limitation, performance-based testing is introduced to supplement conventional volumetric mixture design in assessing the cracking resistance of asphalt mixtures. To perform cracking tests, samples need to be aged to represent the most embrittlement case. The current AASHTO standard for asphalt mixture long-term aging (LTA) is a 5-day oven-aging at 85°C. Quality control/assurance practices require samples to be long-term aged prior to a cracking test which is a time-consuming process. Therefore, it would be beneficial to …
Quality Assessment Of Flexible Pavement Automated Cracking Data In Louisiana, Mostafiz Emtiaz
Quality Assessment Of Flexible Pavement Automated Cracking Data In Louisiana, Mostafiz Emtiaz
LSU Master's Theses
Pavement distress survey is the most critical and integral part of pavement management system. Transportation agencies all over the world depends on the accurate pavement distress survey to take major decisions like pavement rehabilitation or reconstruction. Pavement management at the network level requires accurate pavement distress survey to decide the allocation of budget for pavement maintenance, rehabilitation and reconstruction. This study started collected network-level cracking distress data through manual measurements on high-resolution pavement images and the results were used as the ground truth measurements to evaluate the corresponding automated distress data from the Pavement Management System database. Results showed that …
