Maintenance

Evaluation Of Cost-Effective Pavement Deformation Detection Technologies Using Mobile Lidar

Lateral water drainage on roadways is important to ensure safe and efficient operation and structural condition of the pavement. Pavement rutting could lead to failure in draining water, which poses a hydroplaning risk to drivers due to ponding and loss of skid resistance in wet weather. Traditional data collection methods to identify pavement sections with deformation such as rutting are time-consuming, labor-intensive, and require data collectors to be located on the road, which poses a safety hazard.

Development of Automated Roadway Lighting Diagnosis Tools for Nighttime Traffic Safety Improvement

Roadway lighting is a basic roadway infrastructure to ensure nighttime safety and security for all road users (motorists, pedestrians, cyclists, and transit passengers). To cost-effectively maintain a roadway lighting system, key tasks in infrastructure management include periodically measuring roadway lighting levels, diagnosing lighting performance based on collected data, and providing decision-making support for maintenance and improvement.

Investigation, Testing, and Development of an RFID System for Effective Maintenance of the Existing National Transportation Infrastructure

The focus of this project is the investigation, testing and further development of a RFID system to efficiently maintain the existing transportation infrastructure; especially Roadways and Bridges. For Example, in the event of an active snowfall or blizzard, snow may pile up and ice over on the roadway and bridges causing hazardous conditions for cars and trucks. The current warning systems employed utilizes a LED display board that advises the drivers to take caution, but it does not provide data.

Multi-Criteria Decision-making Approach for Building Resilient and Sustainable Transportation Infrastructure

This project will develop and validate a multi-criteria decision-making approach for enhancing the longevity of transportation infrastructure built on problematic test site conditions that includes poor subsoil conditions. In the United States, the annual cost of damage to constructed facilities built on problematic subsoil conditions was approximately $13 billion, and a significant portion of this amount can be attributed to damages sustained by pavement infrastructure. With continuing pressure on transportation agencies across the nation, several techniques including replacing the existing material and treating the problematic soils were implemented.

Smart Funding Strategies for Maintaining Interdependent Transportation Infrastructure Assets

A road network, consisting of different, but interdependent, transportation infrastructure assets, such as pavements, bridges, signs, etc., supports the mobility, economy, and safety of our society as a whole. According to the 2017 American Society of Civil Engineers infrastructure report card, the U.S. highway system has been underfunded for years. In 2015, 21% of highway pavements are in poor condition, which costs motorists $120.5 billion in extra vehicle repairs and operating costs. Over all, there is a need of $836 billion in repairs and capital investment for America’s highway system.

A Multi‐asset Transportation Infrastructure Asset Management Framework and Modeling for Local Governments

The local governments (LGs) in the Unitized States are managing 3/4 of total 4 million miles of roadway and more than 1/2 of nearly 600,000 bridges, which are critical transportation infrastructure assets to support the mobility, economy, and homeland security in local communities and the nation as a whole. To maintain the aging transportation infrastructure in the state of good repair under the shrinking budget, the state Departments of Transportation (DOTs) have adopted asset management systems (AMSs) to conduct cost‐effective maintenance, rehabilitation, and reconstruction (MR&R).

Fast Reference‐free Crack Measurement (RACM) System in Transportation Infrastructures using Noncontact Ultrasound

The research objectives of this project are the maintenance of transportation infrastructure: i) to develop and improve the reference-free crack measurement (RACM) hardware system for field applications, ii) to develop a post-processing diagnostic framework, iii) to develop monitoring system based on internet of things. In the research category, the reference-free crack measurement system is an innovative technique to improve system efficiency and better maintenance of existing infrastructure.

Evaluation of Pavement Performance Using Remote Sensing Techniques

Annually, transportation agencies spend several millions of dollars of expenditures for their rehabilitation works due to the problematic soils underneath the infrastructure assets. The soils in Dallas-Fort Worth region have high tendency to undergo swell-shrink behavior that contributes to the premature failure of pavements. The proposed research focused on conducting the laboratory tests on the field collected samples and validating their field performance using innovative data collection technologies.
