Development of warrants for installation of dual right-turn lanes at signalized intersections
"Right-turn lanes provide space for the deceleration and storage of right-turn vehicle, and separate turning vehicles from through movements. Dual right-turn lanes are increasingly used at urban intersections primarily for two reason: (1) to accommodate high right-turn demands and avoid turn-pocket overflows, and/or (2) to prevent right-turn vehicles that exit from a nearby upstream freeway off-ramp (on the left of the roadway) from abruptly changing too many lanes toward the right-turn lane at intersection."

Predicting damage in concrete due to expansive aggregates : modeling to enable sustainable material design
"A poroelastic model is developed that can predict stress and strain distributions and, thus, ostensibly damage likelihood in concrete under freezing conditions caused by aggregates with undesirable combinations of geometry and constitutive properties.Sensitivity of the stress distributions to the aggregate and matrix constitutive parameters are assessed to allow improved concrete design."

Portable Emission Measurement System-Based Approach to Developing and Evaluating Driving Cycles for Air Quality Assessment
"The first objective is to develop driving cycles for classified roads incorporating both a vehicle's driving activities and its emission characteristics, using the data collected by Portable Emission Measurement System (PEMS), which was neither available nor has ever been used in developing driving cycles. A comprehensive database is established for the collected data and a sophisticated computer program is developed to generate the specific driving cycles. The second objective is to develop an evaluation approach of driving cycles in which Vehicle Specific Power (VSP), a parameter that can readily connect the driving modes with emissions, is used to evaluate how well the driving cycles can represent the driving and emission characteristics on real roads."

Comprehensive evaluation of compaction of asphalt pavements and development of compaction monitoring system
"This report aimed to conduct a comprehensive evaluation of compaction of asphalt pavements and develop software for monitoring field compaction in real time.The results were used to determine the effects of compaction temperature, compaction method, mixture design, and base type on the compactability of asphalt mixtures.Also in this report researchers developed a system for monitoring and documenting the compaction process of asphalt mixtures called compaction monitoring system (CMS)."

Performance monitoring pavements with thermal segregation in Texas
This report investigated the performance of asphalt surface mixtures that exhibited thermal segregation during construction from 2004 to 2009. The results do not show that thermally segregated locations will fail within three to seven years but they do show that instances of thermal segregation may continue to be anomalous locations in the layer that could lead to failures in the pavement structure.

Materials selection for concrete overlays : information survey review and evaluation of existing concrete overlays in Texas
"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."
