The transportation system is undergoing three revolutions: vehicle automation, electrification, and shared mobility. While these are still nascent trends, studies suggest that they could become ubiquitous in the coming decades. How these revolutionary changes transpire will have significant implications for transportation sustainability. A key factor will be...

Local and regional planners struggle to keep up with rapid changes in mobility patterns. This exploratory research is framed with the overarching goal of asking if and how geo-social network data (GSND), in this case, Twitter data, can be used to understand and explain commuting and non-commuting travel patterns. The research project set out to determine...

This project studied the performance of geotextile-reinforced test sections when compared to an unreinforced case to assess benefit in terms of an extension of the life of the pavement. A single test track was constructed in an indoor test facility and contained two test sections with a reinforcement geotextile (woven and non-woven) while the third section was...

In Texas, and most of the U.S., Class F fly ash is the most used supplementary cementitious material (SCM) due to the many benefits it provides to concrete. In recent years, the availability of Class F fly ash has decreased as many coal-fired power plants have shut down. Plants that have not shut down are required to install various emission control systems...

Bridge load rating assesses the safe live load carrying capacity of an existing or newly designed structure. In addition to load rating with previously defined standard load rating vehicles, the Federal Highway Administration issued additional guidance to states related to rating requirements for all the bridges with respect to specialized hauling vehicles and...
