"In order to keep the rigid pavement (RP) database current and statistically representative of Texas' pavements, periodic reassessments of the database must be made in order to obtain updated sampling plans and new recommendations for future data collection. This report documents a study of the twenty-four-year database, examines the past and current demographics of the data, and identifies the need for improvement in critical areas."

This report presents the results and findings of the first year of this 5-year research project that evaluated the laboratory-field correlation for the Hamburg Wheel Tracking Device (HWTD) equipment.

"This report analyzes and evaluates new information collected in 1998 for the jointed concrete pavement (JCP) database, which currently comprises information on 137 test sections. This report demonstrates the relevance of maintaining the rigid pavement database (RPDB)."

"This report presents the results, findings, conclusions, and recommendations based on the surveys, lab tests, and information collected on the test sections for the first year of a 3 year study. This project is intended to compare the cost-effectiveness, ease and safety of installation, performance, and life-cycle cost for hot rubber asphalt crack sealant, cold pout asphalt emulsion crack sealant, and cold pour asphalt emulsion joint sealant."

"This manual presents a method to proportion concrete paving mixtures made with manufactured sands and increased micro-fines percentages in a step-by-step manner. This method was adapted from Koehler's (2007) proportioning method for self-consolidating concrete" (p. 1).

"This report summarizes the methods, results, and recommendations from a research investigation on the behavior of horizontally curved girders during construction. This information provides guidance on critical issues that bridge engineers face when designing curved steel plate I-girders."

Report on a study examining the effects of variability in mix design of hot-mix asphalt concrete. The study tested the laboratory performance of the asphalt mixes and performed statistical analyses to determine the effects of each variable.

"This report consists of two parts. The first summarizes key details of the Suitability Analysis (SA) model, while the second illustrates the implementation details of the Gravity Land-Use Model (G-LUM). Both modeling approaches have been applied to the Austin region of Texas, but for different case study examples."

This report discusses the significant progress that was made towards developing the Total Pavement Acceptance Device (TPAD) during the first year of Project 0-6005.

"The objective of this study was to extend the work that was conducted under TxDOT Research Project 0-5208 by (a) reviewing the ability of available tools and analysis techniques to quantify and qualitatively describe the (environmental justice) EJ impacts associated with toll road projects and toll road systems through an evaluation of state-of-the-practice applications, and (b) recommending a suitable approach to assess the EJ impacts of toll roads and toll road systems on EJ communities."

"This report documents the results of the work conducted by the Center for Transportation Research (CTR) at the University of Texas at Austin, the Texas Transportation Institute (TTI), and The Center for Multidisciplinary Research in Transportation (TechMRT) at Texas Tech University, to assist TxDOT in developing the elements of the SRP."

"This is a final report of an extensive experimental and analytical examination of the fatigue behavior of the welded end connection used on high-mast light structures and traffic signal masts. The weld details commonly used for these connections produce very poor fatigue performance. Their performance is a function of base plate stiffness, weld type and geometry, and number of anchor bolts. Recommended connections and their corresponding fatigue strength are given as well as recommended fabrication and welding specifications."

"The research described in this report aims to address several of these lingering issues, especially those that are particularly relevant to the state of Texas."

"The goal of the project was to conduct a workshop at CTR and in the Austin District that would educate the visiting peers on TxDOT"s maintenance practices and invite their feedback."

Report on the development of the Texas Flexible Pavement database and the first 7 months of a stage two project, after which the project was terminated.

"This report presents a new approach to the development of such a decision support system with its focus on maintenance management for TxDOT."

"A comprehensive search and review of the use of concrete overlays by the TxDOT districts as well as other DOTs was conducted, with special emphasis focused on gathering information about the constituent materials and mixture proportioning used in the concrete overlays. This review also included new materials such as fibers used in previous studies and new types of fibers currently available. Publications and articles covering the various overlay rehabilitations were used as the background this project, as well as the several studies and implementation projects have been conducted for TxDOT."

"The objective of this research is to validate the pavement Structural Condition Index (SCI) developed under a previous Research Project, 0-4322, and to develop guidelines for implementing the SCI at the network level."

This report summarized the exploration of new methods of protection for the strands used in post-tensioning of concrete bridges.

Report discussing projects initiated under the American Recovery and Reinvestment Act of 2009 (ARRA), a fiscal stimulus package signed by President Obama on March 6, 2009. State agencies like the Texas Department of Transportation (TxDOT) who received ARRA funds had to report, on a monthly basis, various data on each project in the ARRA program, including staff numbers, hours worked, and payroll. TxDOT asked the Center for Transportation Research (CTR) to identify and isolate specific elements of the 0-6592 database that TxDOT's Construction Division (CST) can implement into an existing TxDot database. This report describes the implementation of the database and procedures for updating it.

Report on the application of a paratransit microsimulation patron accessibility analysis tool in four rural transit agencies in workshops. The workshops provided an overview of the Demand Response Transit [DRT] accessibility tool developed by the research team, obtained feedback on the results predicted by the DRT tool, and identified ways to improve the DRT tool.

In February 2010, The Texas Department of Transportation (TcDOT) contracted with the Center for Transportation Research (CTR) at The University of Texas at Austin, the Texas Transportation Institute (TTI), and The Center for Multidisciplinary Research in Transportation (TechMRT) at Texas Tech University, to assist TxDot in developing a Strategic Research Program (SRP). This report documents the work conducted from September 2010 to August 2011.

Report discussing a literature review of current budget cutting strategies used in routine roadway maintenance planning, including methods and techniques that are employed by other state and international transportation organizations (DOT's). It also reviewed methodologies developed from previous research and identified the most effect risk management techniques.

"The objective of the Texas Department of Transportation (TxDOT) Research Project 7-4941 is to; determine the best optimization methodology; evaluate commercial fleet management systems; develop the model if this cost-effective relative to purchasing a commercial model; and validate the new model as needed using data available on TxDOT's current fleet."
