Development and implementation of an engineering productivity measurement system (EPMS) for benchmarking
(2007)
Reliable engineering productivity measurement is a critical element of predictable project performance and continuous improvement. Despite the fact that engineering costs have risen to levels approaching 20 percent of total ...
Dynamic characteristics of municipal solid waste (MSW) in the linear and nonlinear strain ranges
(2007-12)
A series of resonant column and torsional shear (RCTS) and large scale resonant column (LSRC) tests were performed to investigate the dynamic properties (shear modulus and material damping ratio) of municipal solid waste ...
Land use forecasting in regional air quality modeling
(2007-05)
When estimating the impacts of air pollutant control measures on future air
quality, it is typically presumed that land covers remain constant. However, changes in
land cover can have an impact on air pollutant ...
Modeling heterogeneity in transportation infrastructure deterioration: application to pavement
(2007)
One of the key elements for managing transportation infrastructure is to accurately
capture and predict the performance of the facility through well established deterioration
models. A sound deterioration model should ...
Design of MSE retaining walls placed in front of a stable face
(2007-08)
Widening of existing highways often results in new mechanically stabilized earth (MSE) walls being placed in front of existing stable walls. The design of these walls is unique because limited right-of-way often forces the ...
Clustering of air voids around aggregates in air entrained concrete
(2007-05)
Recent research reports have suggested that one of the potential causes of low compressive strengths in air-entrained concrete is the clustering of air voids around the aggregates. The phenomenon of clustering of air voids ...
Laboratory and field investigations on the use of lithium nitrate to prevent or mitigate alkali-silica reaction
(2007-05)
This research project, funded by the Federal Highway Administration (FHWA Project DTFH61-02-C-0097), focuses mainly on alkali-silica reaction (ASR) studies and ways to mitigate the effects of alkali-silica reaction in fresh ...
Measurements of deformations and stresses due to plate out-of-flatness in a steel twin box girder bridge system
(2007-05)
Trapezoidal box girders are frequently used in curved bridge interchanges due to advantages in aesthetics, maintenance, and structural performance compared to comparable I-shaped girders. The smooth shape provides an ...
Planning for strategic change in the project delivery strategy
(2007)
For organizations such as state departments of transportation, other public agencies, or private companies, adopting a new approach to procure services for delivery of construction projects requires significant organizational ...
Offshore outsourcing in global design networks
(2007-12)
Researchers have examined the benefits of outsourcing engineering design services from various perspectives. However, the process by which complex engineering design work is outsourced across international boundaries has ...
