Performance of lap splices in large-scale column specimens affectedby ASR and/or DEF

Description: "This research program conducted a large experimental program, which consisted of the design, construction, curing, deterioration, and structural load testing of 16 large-scale column specimens with a critical lap splice region, and then compared and calibrated models developed in the analytical program with the experimental behavior. Specimens were carefully instrumented both internally and externally to monitor the strain behavior of the concrete and reinforcing steel from specimen constructi… more

Pavement repair strategies for selected distresses in FM roadways

Description: "Expansive soil is considered one of the most common causes of pavement distresses in FM roadways. Depending upon the moisture level, expansive soils will experience changes in volume due to moisture fluctuations from seasonal variations. The objective of this research was to evaluate existing repair projects on selected FM roadways. Those roadways experienced failures in the form of fatigue and rutting in the wheel path, and longitudinal (faulted) cracking including edge cracking. The causes … more

Multi-Vehicle Mobility Allowance Shuttle Transit (MAST) System: An Analytical Model to Select the Fleet Size and a Scheduling Heuristic

Description: This report discusses the mobility allowance shuttle transit [MAST] system which is a hybrid transit system in which vehicles are allowed to deviate from a fixed rout to serve flexible demand. The mixed interfere programming formulation analyzed the impacts of time headways between consecutive transit vehicles on the performance of a two-vehicle MAST system.
