CAM Mix Design With Local Aggregates (open access)

CAM Mix Design With Local Aggregates

"This study provides revised mix design recommendations for crack attenuating mixtures (CAM) with local aggregates. The use of lower quality aggregates is cost beneficial but limits the application of these mixes in terms of reduced performance. Aggregate guidelines and aggregate quality criteria are provided to enhance the rutting and cracking performance of these mixes. The mix design recommendations as well as aggregate guidelines and quality criteria provided in the report are based on laboratory investigations and field validation is strongly recommended before implementation."

Implementing a project and portfolio management system for TxDOT project development (open access)

Implementing a project and portfolio management system for TxDOT project development

"Beginning in the summer of 1999, Texas Department of Transportation (TxDOT) started developing the framework for implementing a sophisticated new system to manage its large and diverse portfolio of projects during their development phase. This was followed by the implementation itself for managing project schedules, project and portfolio resources and costs during their development cycle. This unique and challenging implementation across TxDOT encompassed all functional areas involved in the project development phase. It was successfully completed by overcoming technical, technological, and cultural challenges inherent with any implementation of this scale and magnitude."

Continuous prestressed concrete girder bridges. Volume 1, Literature review and preliminary designs (open access)

Continuous prestressed concrete girder bridges. Volume 1, Literature review and preliminary designs

"The Texas Department of Transportation (TxDOT) is currently designing typical highway bridge structures as simply supported using standard precast, pretension-ed girders. TxDOT is interested in developing additional economical design alternatives for longer span bridges, through the use of the continuous precast, pretension-ed concrete bridge structures that use spliced girder technology. The objectives of this portion of the study are to evaluate the current stat-of-the-art and practice relevant to continuous precast concrete girder bridges and recommend suitable continuity connections for use with typical Texas bridge girders."

Developing a mixture design specification for flexible base construction (open access)

Developing a mixture design specification for flexible base construction

"In the Texas Department of Transportation (TxDOT), flexible base producers typically generate large stockpiles of material exclusively for TxDOT projects. This large "state-only" inventory often maintained by producers, along with time requirements for testing and reduced manpower within TxDOT offices, resulted in this project's investigation into a mixture-design specification for flexible base. The goals of this project are to develop a flexible base specification that reduces TxDOT's burden for sampling and testing, reduces time and space burdens on producers for maintaining TxDOT-only stockpiles, and maintains or improves the quality of the base."

Characterization of Exhaust Emissions From Heavy-Duty Diesel Vehicles in the Houston-Galveston-Brazoria Area

"For this study, a total of 30 heavy-duty diesel vehicles (HDDVs) were selected from City of Houston (COH) fleet based on opacity testing for HEs and random selection for non-HEs. With the selected 30 vehicles, driving and idling emission testing were performed to characterize their emissions with respect to vehicle classes, types (HE or non-HE), and model years."
