This report presents the preliminary findings from a study conducted to investigate the influence of chemical warm mix asphalt (WMA) additives and reduced aging on the viscosity, stiffness, susceptibility to permanent deformation, fracture resistance, and thermal cracking resistance of asphalt binders.

"This report contains best practices for choosing appropriate locations and design concepts for Texas roundabouts. This research effort is comprised of the following components: synthesis of available literature and analysis methods, development of capacity analysis methods, validation and enhancement of existing tools, and a spreadsheet tool to aid in roundabout planning and implementation."

"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."

"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."

"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."

"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 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 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."

"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 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 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.

"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."

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

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

"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."

"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 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.
