"This three-year research effort was undertaken to identify factors that influence the number and severity of roadway departure crashes on rural two-lane highways in Texas and provide engineering countermeasures to reduce this type of crash. The study objectives were accomplished by analyzing crash, traffic flow, and geometric data between 2003 and 2008 and conducting site visits at 20 sites having the highest crash rates at four TxDOT districts."

Technical report on the advantages of two-lift concrete paving (2LCP) instead on a single homogeneous layer.

"Expansive soil is considered one of the most common causes of pavement distresses in FM roadways. Depending upon the moisture level, expansive soils will experience changes in volume due to moisture fluctuations from seasonal variations. The objective of this research was to evaluate existing repair projects on selected FM roadways. Those roadways experienced failures in the form of fatigue and rutting in the wheel path, and longitudinal (faulted) cracking including edge cracking. The causes of those failures were mainly linked to high PI expansive soil and narrow pavement" (from abstract).

This report provides guidance towards defining adverse drainage structures for mitigation of hydrologic and hydraulic impacts.

"This research project evaluates numerous transportation issues and develops findings and/or recommendations based on results. This project has been structured to address some of the emerging, critical, and unique considerations related to transportation."

"This project conducted state-of-the-practice surveys, focus groups, and driver surveys to develop test signs used for field deployment and evaluation regarding lane assignment on frontage roads and cross streets."
