The high amount of confining lateral steel required by seismic design provisions for rectangular bridge columns can cause steel congestion. The high amount of confining steel may hinder the placement of conventional concrete (CC). Self-consolidating concrete (SCC) eliminates or reduces concrete placement...

 

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...

 

Recent studies have shown that the use of self-consolidating concrete (SCC) results in improved finished quality, increased production efficiency, and reduced labor cost. Because of the favorable properties that SCC exhibits, the Federal Highway Administration and the precast concrete industry have been...

 

Coal ash is the portion of ash rejected by the stack and collected at the base as a waste product. Coal ash is comprised of bottom ash and fly ash. Fly ash accounts for 70 percent to 80 percent of total coal ash and the rest being bottom ash. Only 39 percent of bottom ash is utilized with the rest being...

 

The main objective of this study was to investigate the effect of the addition of a coal combustion remnant called bottom ash into asphalt mixes. The intent was to determine if mixes prepared with bottom ash showed degradation of desirable performance measures when compared to control mixes. This was...

 

This research investigates moisture susceptibility of asphalt mixes; evaluates the effect of various numbers of freeze-thaw cycles on the mechanical properties of asphalt and determines if the Georgia Loaded Wheel Tester can be used to test for moisture induced damage.

 

This project used field and laboratory evaluations to study the possibility of incorporating bottom ash in asphalt mixes. A pavement test section was constructed for the field portion of the project. The laboratory evaluations involved design and accelerated testing of control and bottom ash asphalt...

 

This report examines the feasibility of using the thermal stress restrained specimen test to evaluate low temperature cracking in asphalt pavement mixes. Data were collected from laboratory and field evaluations. Various mixing, aging, and compaction methods were used to prepare test samples with materials...

 

In this study, the researchers evaluated the performance of asphalt mixes prepared using the Marshall mix design method and the Superpave level one mix design method. The Georgia Loaded Wheel Tester and the Thermal Stress Restrained Specimen Tester were used to test the rut-resistance and low-temperature...

 

This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures...
