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."

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.

Upflow Calcite Contractor Study
This document reports "four experiments [that] were conducted in four phases to determine design criteria for reverse osmosis permeate stabilization. The first three phases of experiments involved varying one of three design parameters (calcite particle size, calcite purity, and EBCT) and holding for these parameters to validate the design criteria values developed using the results of the first three experiments."
