Expanded Polystyrene (EPS) geofoam is a super-lightweight material used in various transportation engineering applications. It has been particularly successful as an ultra-lightweight alternative to earthen, geosynthetic reinforced soil (GRS), and mechanically-stabilized earth (MSE) embankment systems...

 

Connections between precast concrete elements must be able to withstand significant stresses and deformations in earthquakes. The grouted splice sleeve (GSS) connector is being considered for connecting footing, column, and cap beam elements in accelerated bridge construction (ABC). There are limited...

 

This report presents an initial investigation of the mechanics of I-beams developed with plastic-aluminum composite technology. Plastic-aluminum composites in structural beam/frame/truss elements are a relatively new concept that has seen little, if any, application in modern construction. This technology...

 

Simple-made-continuous (SMC) steel bridges are a relatively new innovation in steel bridge design. The SMC concept is a viable solution for steel bridges to recover market share of the bridges constructed in the United States. The majority of SMC bridges currently in use are constructed with concrete...

 

This paper presents the results of an experimental study on the fatigue performance of RC beams strengthened with different externally bonded CFRP systems. Seven specimens were fabricated; three had no CFRP; the remaining four had one of two CFRP systems. The objective of this study was to determine...

 

The 24/7 Sobriety Program is an intervention strategy mandating that repeat impaired driving offenders remain sober as a condition of bond or pre-trial release. The goal is to monitor the most dangerous offenders in North Dakota and require that these individuals remain sober in order to keep roadways...

 

The overall project is to demonstrate the effectiveness of shear spiking (technique already developed through a previous project). Many timber railroad bridges are deficient but it is too costly to replace them; hence, inexpensive repair techniques are needed. The proposed project will provide the necessary...

 

Field samples were obtained from cores taken from multiple roads around the Salt Lake Valley in Utah and prepared for BBR testing. The response of field cores showed that even though the same binder grade used in the region was the same, the resulting mixtures have significant differences in creep moduli...

 

Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also...

 

Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability...
