Technical Learning Opportunities
Maintenance and preservation of our flexible pavements is essential to providing a quality roadway to the public. This presentation will discuss the identification of cracking, common causes for cracking, and best practices for sealing cracks. Unfortunately, sometimes the roadway gets away from us forcing...
Several mechanisms exist for identifying sites for upgrading transportation infrastructure for non- emergency maintenance. One key element is the complaints that citizens make about broken or missing features using the 311-service call system. Researchers argue, however, that the types and rates of complaints...
The overarching goal of the research is to explore a sustainable solution that can extend the longevity of constructed bridge decks by placing an overlay system with a state-of-the-art construction material, ultra-high performance concrete (UHPC). Specific objectives are: To fundamentally understand...
Accurate pavement assessments are critical for effective maintenance and asset management. However, traditional methods can be time-consuming and labor-intensive. This research explores an innovative approach using AI, deep learning, and advanced imaging to automate distress detection, severity estimation...
Results, best practices and lessons learned from implementations of Diverging Diamond Interchanges (DDI) and Continuous Flow Intersections (CFIs) in Utah Establishing performance metrics and evaluation criteria to assess the success and effectiveness of DDIs and CFIs to support their planning, design...
Truck platooning presents a promising solution for reducing fuel consumption and emissions while enhancing freight transport capacity. However, the adaptivity of this technology to diverse roadway infrastructure remains a critical research need. This project aims to address the needs by designing and...
This is part 2 of 3 in the Culvert Hydraulics Series. In this presentation, we will discuss various design criteria, define inlet and outlet controls, and prove an understanding of conventional culvert design procedures. The speaker will then introduce FHWA resources: hydraulic toolbox, HY-8 and offer...
This is part 3 of 3 in the Culvert Hydraulics Series. In this presentation, we will discuss principles of culvert inspections, inspection procedures and recognize criteria impacting decisions to rehab or replace, as well as common methods of culvert repair work. We will then take a look at some failure...
The South Dakota Department of Transportation (SDDOT) allows the use of precast double-tee bridges in counties because they are economical and fast in construction. Alternative durable prefabricated bridge systems are needed to provide more options to local governments. The present study was carried...
