Highway safety design workshops

Highway safety design workshops

Date: November 2010
Creator: Bonneson, James A. & Pratt, Michael P.
Description: Highway safety is an ongoing concern for the Texas Department of Transportation (TxDOT). As part of its proactive commitment to improving highway safety, TxDOT is moving toward including quantitative safety analyses earlier in the project development process. To assist in achieving this goal, TxDOT research project 0-4703 developed the Roadway Safety Design Workbook for engineers responsible for highway geometric design. This Workbook describes quantitative safety relationships for specific design components known to be correlated with crash frequency. As part of TxDOT Project 0-4703, a series of workshops were developed to share safety information with TxDOT roadway designers. Information in the Workbook was used as the basis for the workshops. The workshops addressed rural highways, urban streets, and freeways. They included a mixture of classroom discussion and hands-on training activities for the participants. The participants indicated that the information presented in the workshops will be beneficial as they make decisions about highway safety improvements.

Performance of lap splices in large-scale column specimens affectedby ASR and/or DEF

Performance of lap splices in large-scale column specimens affectedby ASR and/or DEF

Date: June 2012
Creator: Bracci, Joseph M.; Gardoni, Paolo; Eck, Kathleen M. & Trejo, David
Description: "This research program conducted a large experimental program, which consisted of the design, construction, curing, deterioration, and structural load testing of 16 large-scale column specimens with a critical lap splice region, and then compared and calibrated models developed in the analytical program with the experimental behavior. Specimens were carefully instrumented both internally and externally to monitor the strain behavior of the concrete and reinforcing steel from specimen construction, curing, deterioration, and final structural load testing."

Realtime monitoring of bridge scour using remote monitoring technology

Realtime monitoring of bridge scour using remote monitoring technology

Date: February 2011
Creator: Briaud, Jean-Louis; Hurlebaus, Stefan; Chang, Kuang-An; Yao, Congpu; Sharma, Hrishikesh; Yu, Ok-Youn et al.
Description: The research performed in this project focuses on the application of instruments including accelerometers and tiltmeters to monitor bridge scour. First, two large scale laboratory experiments were performed. One experiment is the simulation of a bridge with a shallow foundation, and the other is the simulation of a bridge with a deep foundation. A series of instruments were installed on the simulated bridge to monitor the performance of the bridge due to scour. Both the shallow foundation experiment and deep foundation experiment show that accelerometers and tiltmeters can be used in scour monitoring events since both give warning of bridge failure successfully. Subsequently, two individual monitoring systems were designed and installed on two bridges: US59 over Guadalupe River Bridge and SH80 over San Antonio River Bridge in Texas. Realtime data are collected and transmitted to a computer server at Texas A&M University, which can be accessed remotely. The instrumentation on the two bridges does not show great hope of application of accelerometers to monitor bridge scour because of a lack of sufficient excitation from traffic. Another issue with the accelerometers is the high power consumption during the transmission of accelerometer data, which cannot be satisfied with a typical solar panel ...

Texas Urban Triangle: creating a spatial decision support system for mobility policy and investments that shape the sustainable growth of Texas

Texas Urban Triangle: creating a spatial decision support system for mobility policy and investments that shape the sustainable growth of Texas

Date: November 2010
Creator: Bright, Elise M.; Morgan, Curtis Alan & Neuman, Michael
Description: "This project came into being due to the dramatic transformation of the four core Texas metropolitan areas into an emergent megalopolis: Dallas-Fort Worth, Houston, San Antonio, and Austin. Its aims are two-fold: to provide a framework for decisions about future growth in the fastest growing region of Texas, and to spur further research into the complexities of this vast and rapidly emerging mega-region. The Texas Urban Triangle - 17 million persons spread over 58,000 square miles - is a new urban phenomenon, a triangular megalopolis whose development is not linear and contiguous. This report gives policy makers and investors from all sectors of society the critical knowledge they need to make decisions that will shape the future of Texas. The Texas Urban Triangle is one of the most dynamic urban regions in the nation, and to ensure it continues to flourish, we must build a future based on sustainable growth principles. Our preliminary findings suggest that this is not always the case. Further research needs to be conducted to obtain a complete, detailed, and comprehensive portrait. Nonetheless, even these preliminary findings are robust and point to more sustainable options for the future. Now that this preliminary analysis has been completed, ...

Microsurfacing in Texas

Microsurfacing in Texas

Date: August 2011
Creator: Broughton, Benjamin & Lee, Soon-Jae
Description: This report describes the current state of practice of microsurfacing in Texas and compares it to best practices extracted from existing literature. A survey of DOT personnel, contractors and emulsion suppliers in Texas provides insight into the most crucial factors contributing to the success or failure of a microsurfacing. From the results of the survey, literature reviews, case studies and site visits, the research team analyzed material selection and mix design methods, construction practices, equipment practices and performance measures for microsurfacings.
