An alternative transportation fuels update : a case study of the developing E85 industry

An alternative transportation fuels update : a case study of the developing E85 industry

Date: October 2011
Creator: Travare, Papa S. & Lewis, Sharon
Description: "As the United States imports more than half of its oil and overall consumption continues to climb, the 1992 Energy Policy Act established the goal of having "alternative fuels" replace at least ten percent of petroleum fuels used in the transportation sector by 2000, and at least thirty percent by 2010. Currently, alternative fuels consumed in Alternative Fuel Vehicle (AFVs) account for less than one percent of total consumption of gasoline. This paper examines how alternative fuel E85 can be used to reverse that trend. In addition, this research paper will take a look at some of the ongoing government decisions concerning the use of the alternative fuel E85, and will discuss what policy makers might hold for the future in terms of the supply and demand of alternative fuels in the United States. This case study will be useful to all stakeholders involved in the transportation industry, including, but not limited to the government, policy makers, automakers, motorists, and researchers, eager to find a just balance with both a better transportation system and a healthy and clean environment."

Compendium of student papers:  2010 undergraduate transportation scholars program

Compendium of student papers: 2010 undergraduate transportation scholars program

Date: June 2011
Creator: Hawkins, H. Gene; Almy, Isaac; Ballard, Lance; Brimley, Bradford; Huff, William; Larson, Gregory et al.
Description: "This report is a compilation of research papers written by students participating in the 2010 Undergraduate Transportation Scholars Program. The 10-week summer program, now in its 20th year, provides undergraduate students in Civil Engineering the opportunity to learn about transportation engineering through participating in sponsored transportation research projects. The program design allows students to interact directly with a Texas A&M University faculty member or Texas Transportation Institute researcher in developing a research proposal, conducting valid research, and documenting the research results through oral presentations and research papers. The papers in this compendium report on the following topics, respectively: 1) estimating carriers/truckers value of time due to congestion; 2) evaluating retroreflectivity measurement techniques for profiled and rumble stripe pavement markings; 3) analyzing retroreflectivity and color degradation in sign sheeting; 4) evaluating the effectiveness of LED enhanced stop paddles for school crossing guard use; 5) incorporating freight value into the Urban Mobility Report; 6) evaluating ASTM Standard Test Method E2177, retroreflectivity of pavement markings in a condition of wetness; 7) calibrating pavement performance prediction models; and 8) evaluating the effects of concrete curing compounds on hydration."

The design of a comprehensive microsimulator of household vehicle fleet composition, utilization, and evolution

The design of a comprehensive microsimulator of household vehicle fleet composition, utilization, and evolution

Date: January 2012
Creator: Paleti, Rajesh.
Description: "The report describes a comprehensive vehicle fleet composition, utilization, and evolution simulator that can be used to forecast household vehicle ownership and mileage by type of vehicle over time. The components of the simulator are developed in this research effort using detailed revealed and stated preference data on household vehicle fleet composition, utilization, and planned transactions collected for a large sample of households in California. Results of the model development effort show that the simulator holds promise as a tool for simulating vehicular choice processes in the context of activity-based travel microsimulation model systems."

Designing Fine Aggregate Mixtures to evaluate fatigue crack growth in asphalt mixtures

Designing Fine Aggregate Mixtures to evaluate fatigue crack growth in asphalt mixtures

Date: April 2001
Creator: Bhasin, Amit; Motamed, Arash & Izadi, Anoosha
Description: "Fatigue cracking is a significant form of pavement distress in flexible pavements. The properties of the sand-asphalt mortars or fine aggregate matrix (FAM) can be used to characterize the evolution of fatigue crack growth and self-healing in asphalt mixtures. This study compares the internal microstructure of the mortar within a full asphalt mixture to the internal microstructure of the FAM specimen. This study also conducts a limited evaluation of the influence of mixture properties and methods of compaction on the engineering properties of the FAM specimens. The results from this study, although limited in number, indicate that in most cases the SGC compacted FAM specimen had a microstructure that most closely resembled the microstructure of the mortar within a full asphalt mixture. Another finding from this study was that, at a given level of damage, the healing characteristic of the three different types of FAM mixes was not significantly different. This indicates that the healing rate is mostly dictated by the type of binder and not significantly influenced by the gradation or binder content, as long as the volumetric distribution of the mastic was the same. In other words, the inherent healing characteristics of the asphalt binder play a more ...
