Evaluation Of The Rheological Behaviors And Molecular Composition Properties Of Crumb Rubber Modified Emulsion For Chip Seal, Md Tanvir Ahmed Sarkar
Evaluation Of The Rheological Behaviors And Molecular Composition Properties Of Crumb Rubber Modified Emulsion For Chip Seal, Md Tanvir Ahmed Sarkar
LSU Master's Theses
An experimental study was conducted to characterize the chemical, molecular, and rheological properties of different asphalt emulsions including a newly introduced tire rubber modified asphalt emulsion. One tire rubber modified asphalt emulsion (CRS-2TR), two conventional emulsions (CRS-2 and CRS-2P), and one asphalt rubber binder (AC20-5TR) were evaluated. The differences in functional groups, chemical composition, and molecular weight distribution of the asphalt binder and emulsions under different aging conditions (Original, RTFO-aged, and PAV-aged) were evaluated by the Saturates, Aromatics, Resins and Asphaltenes (SARA) fractionation test, High-Pressure Gel Permeation Chromatography (HP-GPC), and Fourier Transform Infrared Spectroscopy (FTIR) test, respectively. Superpave Performance Grade …
Evaluation Of Traffic Speed Deflectometer For Pavement Structural Evaluation In Louisiana, Zia Uddin Ahmed Zihan
Evaluation Of Traffic Speed Deflectometer For Pavement Structural Evaluation In Louisiana, Zia Uddin Ahmed Zihan
LSU Master's Theses
Many state agencies have recognized the importance of incorporating pavement structural conditions in the selection of maintenance and rehabilitation (M&R) strategies along with functional indices. To measure in-service pavement structural capacity, surface deflection under a defined load has been typically used. The Rolling Wheel Deflectometer (RWD) and Traffic Speed Deflectometer (TSD) have emerged as continuous pavement deflection-measuring devices as they operate at traffic speed and reduces lane closure and user delays.
The research objective of this study was to assess the feasibility of using TSD measurements at the network-level for pavement conditions structural evaluation in Louisiana. To achieve the objectives …

A Decision-Making Tool For Incorporating Cradle-To-Gate Sustainability Into Pavement Design, Sujata Subedi
LSU Master's Theses
The need to continually maintain an aged and crumbling national roadway network, together with a growing demand for upgrading has resulted in major environmental and economic impacts around the nation. This has led to an interest in developing a structured framework to quantify the sustainability performance of pavements by balancing economic and environmental performance against engineering criteria. This study developed an Environment Product Declaration (EPD) based, decision-making framework to quantify the sustainability of pavement design alternatives. In this study, the sustainability of pavement is described in tandem with Environmental and Economic performance criteria. First, the Environmental analysis was inclusive of …
Examining The Effect Of Multiple Route Choice Criteria On Hurricane Evacuation Traffic Through External Validation Of Simulations, Haggai D. Davis Iii
Examining The Effect Of Multiple Route Choice Criteria On Hurricane Evacuation Traffic Through External Validation Of Simulations, Haggai D. Davis Iii
LSU Master's Theses
Hurricane evacuations can be a chaotic experience for individuals involved, but researchers have attempted to find patterns in the routes people take. One paper laid out a model for predicting route choice based upon features that are different than standard route choice influencers. This thesis attempted to evaluate the accuracy of that model by using TransModeler modeling software. Using the building blocks of the HEMP project, this project compared the new model to the standard model and evaluated the two based upon the ability to reproduce real-world results. Interestingly, the two did not come out significantly different possibly because the …
Effect Of Different Traffic Signal Control Plans On Simulation Of Hurricane Evacuation Traffic, Divya Kolasani
Effect Of Different Traffic Signal Control Plans On Simulation Of Hurricane Evacuation Traffic, Divya Kolasani
LSU Master's Theses
The majority of hurricane evacuation modeling studies concentrate on evacuation traffic on freeways with relatively little attention being given to traffic on arterials. This study is focused on evaluating the evacuation efficiency of a network under different traffic signal settings on arterials using microscopic simulation. This is achieved by changing the traffic signal settings from existing signal timing plans to flashing yellow on major evacuation routes and flashing red on cross streets, for a given evacuation order. Time-dependent origin-destination matrices for hurricane evacuation up to 72 hours away from landfall for No Evacuation order, as well as a Voluntary/Mandatory Evacuation …
