MASH test 3-11 on the 5-inch cast in place deck barrier anchors

MASH test 3-11 on the 5-inch cast in place deck barrier anchors

Date: October 2011
Creator: Bligh, Roger P.; Menges, Wanda L. & Arrington, Dusty R.
Description: "A full-scale crash test was performed to evaluate the impact performance of a Texas T223 concrete beam and post bridge rail anchored to a 5-nch cast-in-place deck (CIPD). The testing followed the MASH standards for Test Level 3 ( TL-#) longitudinal barriers. The test performed was American Association of State Highways and Transportation Officials (AAHSTO) Manual for Assessing Safety Hardware (MASH) test 3-11, which involves a 2270P (500 lb) pickup truck impacting the critical impact point (CIP) of the barrier at a nominal impact speed and angle of 62 mi/h and 25degress, respectively. This test evaluated the strength of the barrier and its anchorage to the 5-inch CIPD."

MASH test 3-37 of the TxDOT 31-inch w-beam downstream anchor terminal

MASH test 3-37 of the TxDOT 31-inch w-beam downstream anchor terminal

Date: October 2011
Creator: Bligh, Roger P.; Menges, Wanda L. & Arrington, Dusty R.
Description: Report discussing the findings of a study into issues related to roadside safety devices: "The objective of this study was to develop a suitable replacement for the downstream 'turn-down' guardrail anchor system. The 'turn-down' guardrail anchor system does not meet mandated test requirements under MASH for upstream anchor application terminals; however, it does meet downstream requirements for previous crash testing standard" (abstract). It includes background information, system details, test requirements and evaluation criteria, crash test procedures, crash test results, and conclusions.

Determination of minimum height and lateral design load for MASH test level 4 bridge rails

Determination of minimum height and lateral design load for MASH test level 4 bridge rails

Date: October 2011
Creator: Bligh, Roger P.; Menges, Wanda L. & Sheikh, Nauman Mansoor
Description: "This research had the objectives of determining the minimum rail height and lateral design impact load for MASH test level 4 bridge rails. Using parametric finite element analysis and subsequent crash testing, the researchers determined the minimum recommended rail height for MASH TL-4 impact conditions to be 36 inches. Later Design impact for MASH TL-4 test conditions was determined to be 80 kips."

Delivery of workshops on corridor management and preservation in Texas

Delivery of workshops on corridor management and preservation in Texas

Date: September 2010
Creator: Bochner, Brian S. & Hard, Edwin N.
Description: "This report summarizes the delivery and outcome of a series of workshops conducted at 23 Texas Department of Transportation (TxDOT) districts across the state on corridor management and preservation in Texas. The workshops served as follow-up implementation work for research project 0-5606, "Creating Partnerships with Local Communities to Manage and Preserve Corridors." The report provides an overview of the project and documents the dates, locations, and attendance of workshops implemented during the three-year project period."

Internal trip capture estimator for mixed-use developments

Internal trip capture estimator for mixed-use developments

Date: February 2010
Creator: Bochner, Brian S. & Sperry, Benjamin R.
Description: This report describes a spreadsheet tool for estimating trip generation for mixed-use developments, accounting for internal trip capture. Internal trip capture is the portion of trips generated by a mixed-use development that both begin and end within the development. The importance of internal trip capture is that those trips satisfy a portion of the total development's trip generation and they do so without using the external road system. As a result, a mixed-use development that generates a given number of total trips creates less demand on the external road system than single-use developments generating the same number of trips. This report describes the spreadsheet estimator and how to use it. It describes the data behind the estimator as well as how those data are applied. The two Texas mixed-use developments from which most of the data were derived are also described. This report is supplemented by the Excel® spreadsheet itself as well as task memoranda that document the survey data collected as part of this project.

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.
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."
