Ground Tire Rubber (GTR) as a Stabilizer for Subgrade Soils The objective of this research is to determine the key pavement engineering properties for blends of GTR and highway subgrade soils. These findings will be used to develop recommendations detailing how the acceptable blends should be used in FDOT’s highways.
Extensive research on Reclaimed Asphalt Pavement (RAP) indicates that it possesses both positive and negative engineering behavior. On the plus side, it is a drainable granular material with adequate shear strength, however, engineering concerns arise because RAP exhibits both low bearing ratios and extensive creep , , .
This research investigates the capabilities and limitations of using an unmanned aerial video data collection system to assist structural inspectors during the inspection process of bridges and high mast lighting poles. The proposed system has the potential to improve the safety of inspectors during the inspection process, improve the accuracy of the estimates made by inspectors, and reduce the cost of inspections.
This research investigates the applicability of mobile light detection and ranging (LiDAR) and imaging data for railroad bridge inspections. Using high-definition cameras, images of bridge defects (e.g., concrete cracks) will be collected and processed to develop prototypes of image processing algorithms for defect detection and classification. Using a state-of-the-art mobile LiDAR sensor, data will be collected and processed to develop prototype 3D models of bridge structures. The resulting 3D models will be used to detect particular bridge defects, such as structural deformations.
This project applies an interdisciplinary approach to curriculum development to create courses, lecture modules and laboratory experiments related to hydrogen and fuel cells. Project assessment will determine the effectiveness of the laboratory curriculum. Classes improved by this project will provide public and private sectors with skilled employees and researchers in hydrogen technology. The hydrogen-based curriculum will further the student understanding of hydrogen and fuel cell technologies and offer undergraduate and graduate students a career path into renewable energy.
The main purpose of this project is to explore the potential use of fiber reinforced concrete for concrete pavement slab replacement. Several types of fiber including steel, glass and synthetic fibers were investigated.
