Implementation of Database for TxDOT ARRA Projects
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.

Application guide and specifications for geotextiles in roadway applications
Abstract: "Geotextiles, one among the different geosynthetic products, can be used for a number of functions or applications in pavement design. The benefits of using geotextiles in pavements and other transportation applications have triggered a proliferation of products. While this abundance of new products has led to reduction in costs, it has also made it difficult for TxDOT personnel to choose appropriate products based on their engineering properties. Consequently, this report provides the basis for (i) guidelines for proper use and selection of geotextiles in pavements, (ii) material specifications for geotextiles in pavement applications, and (iii) draft construction specifications."
