The Use of Porous Concrete for Sidewalks
Pervious concrete has been increasing in popularity as a potential solution to reduce the amount of impermeable surface area associated with sidewalks, reduce puddling, and potentially slow storm water surface high-flow rates. As important as these benefits are to surface runoff mitigation, there are concerns with the ab…

Validation and Refinement of a Novel Deicing System for Stay Cables
The goal of this research project is to validate and provide a basis to improve and refine a novel de-icing system for stay-cables. This autonomous de-icing system shows significant potential to cost-effectively remove ice build-up without damaging the protective system of the underlying stay-cable. However, currently th…

Residual Capacity of Impacted Bridge Piers
This project seeks to experimentally determine a predictive methodology for calculating capacity reduction values for vehicular impacted bridge piers. To accomplish this goal, the following more specific objec…
Bond Performance of 1.125-inch-diameter Prestressing Strands
The public desires less disruption to highway services in addition to cheaper and more aesthetically pleasing structures. To meet these needs, engineers are continuously pushing the limits of current designs. One way to decrease the costs of an expensive structure is to limit the number of supports, provide longer span l…
Long-Term Monitoring of a Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS)
The geosynthetic reinforced soil integrated bridge system (GRS-IBS) is an innovative alternative to conventional bridge technology that utilizes closely spaced layers of geosynthetic reinforcement and compacted granular fill material to provide direct bearing support for structural bridge members. Using this technology, …
Development of Concrete Mix Proportions for Minimizing/Eliminating Shrinkage Cracks in Slabs and High Performance Grouts
The primary objectives are two develop two formulations, one suitable for casting slabs with least amount of creep and shrinkage and eliminate cracking due to restrained time-dependent strains and the second for specialized uses in grouting and gluing for pre-cast construction. The first part of the research will utilize…
Evaluation of Repair Techniques for Impact-Damaged Prestressed Beams
Collisions between over height vehicles and bridges occur about 1,000 times per year in the United States. Collision damage to bridges can range from minor to catastrophic, potentially requiring repair or replacement of a bridge beam. For prestressed concrete beams, the traditional repair methods are strand splices and F…
