Application guide and specifications for geotextiles in roadway applications (open access)

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."

Identification of priority rail projects for Texas: initial methodology/user manual and guidebook

"This project developed a system of evaluative tools for the Texas Department of Transportation (TxDOT) to prioritize its investments in rail-related projects on a statewide basis. This work is meant to ensure that the limited available funding for rail projects is applied in the most beneficial and efficient manner and is focused upon addressing TxDOT's strategic goals. From the findings, researches recommend a transparent methodology for evaluating proposed rail projects and establishing an initial process through which rail-related investments can periodically be re-evaluated."

Development of a precast bridge deck overhang system

This research investigated the overhang and shear capacity of a precast overhang system for potential use during the construction of bridges with precast overhang panels. The research was performed in three phases: the Phase 1 research including work specifically for the Rock Creek Bridge in Parker County, Texas; the Phase 2 research for general precast overhang panels, and; the Phase 3 research investigating the shear capacity. Grout material characteristics were also assessed for possible use in the haunch; constructability issues were also addressed.

Realtime monitoring of bridge scour using remote monitoring technology (open access)

Realtime monitoring of bridge scour using remote monitoring technology

Report on research performed on the application of instruments including accelerometers and tiltmeters to monitor bridge scour. 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. Tiltmeters can provide the integral behavior of the bridge, and therefore are very useful devices for scour monitoring. Guidelines and protocols for scour monitoring based on the US59 over Guadalupe River Bridge and the SH80 over San Antonio River Bridge are provided in the study.
