Ohio to Share Lessons Learned Using Knuckleboom Crane for Debris Removal November 16, 2021 - As part of its ongoing research to improve bridge and channel maintenance practices, the Ohio Department of Transportation (ODOT) teamed with the Ohio State University (OSU) to develop the knuckleboom crane, an innovative tool that allows maintenance crews to safely and efficiently remove the debris that accumulates around bridge piers in larger rivers.
To help other agencies understand the background, benefits and challenges behind the research, representatives from ODOT and researchers from OSU will discuss the project and answer attendees’ questions during a one-hour virtual presentation on November 30, beginning at 1:00 p.m. Eastern.

Utah Identifies Replacement Cycles for Three Types of Trucks November 2, 2021 - As maintenance vehicles get older, it can be challenging for any transportation agency to balance the price of replacement with the increasing costs of maintenance and repairs. Taking a data-driven approach, researchers for the Utah Department of Transportation conducted life-cycle analyses for three common maintenance vehicles: loaders, sweepers and graders. Considering the vehicles’ acquisition price, depreciation value and estimated maintenance needs, the researchers’ recommendations can help agencies prepare for the substantial expense of replacing these vehicles.

Vermont Measures Effectiveness of Erosion-Mitigation Efforts October 26, 2021 - Unpaved roads are prone to stormwater runoff and erosion, which can have a variety of negative impacts on the quality of downstream waters.
Building upon its previous research identifying effective erosion-mitigation practices, Vermont Agency of Transportation documented erosion rates and soil-contamination at drainage sites and culvert outlets to estimate which practices have proven most successful.

Iowa Assesses Future Risks to Prioritize Maintenance Needs October 19, 2021 - As floods and other extreme weather events become more intense and frequent, the risk and potential damage to roads, bridges and other transportation infrastructure also rises.
Looking at historic damage, flood-prone areas, structural ratings and other measures, Iowa DOT developed a variety of methodologies to identify the most vulnerable pavements, structures and other critical assets across the state. The research findings will help the agency prioritize its maintenance and planning efforts and allocate resources efficiently in preparation for future natural disasters.

How to Recruit and Retain Highway Maintenance Workers October 12, 2021 - Finding and keeping a committed maintenance workforce has become a challenge for transportation agencies nationwide.
To identify the successful strategies in both the public and private sectors, investigators for the Clear Roads winter maintenance pooled fund surveyed and interviewed more than 150 individuals representing state and local DOTs and private contractors.
The research resulted in a set of case studies and recommendations to help employers attract and keep a modern, committed workforce.

Ideas and Insights Exchanged at September No Boundaries Meeting September 30, 2021 - No Boundaries held its second peer exchange of 2021 from September 14-15 with an in-person meeting in Denver that included a simultaneous virtual option for remote participants.
Utah Explores the Feasibility of Alternative Fuel Maintenance Vehicles September 22, 2021 - Vehicles powered with alternative fuels offer an attractive option for a transportation agency looking to address the carbon emissions of its maintenance fleet. However, deciding which vehicles and technologies to choose can be complicated from both financial and technical perspectives.
To make the process of replacing its maintenance vehicles easier, the Utah Department of Transportation developed a mathematical model that considers the lifetime costs of the vehicles. The result show which types of vehicles should be purchased and salvaged and in what year, maximizing the total fleet costs.

Webinar to Highlight Pavement Preservation Specifications September 7, 2021 - The Transportation Research Board will host the webinar, “Chip Seals, Microsurfacing, and Fog Seals Specifications” on Tuesday, September 14 from 1:00 – 3:00 p.m. Eastern.
The program will present the findings from a recent study and guide, and discussions will include how the guide can provide complete construction specifications or supplement existing pavement preservation practices.
Arizona Evaluates Options to Extend Service Life of Pavement Markings August 25, 2021 - Weather, temperature fluctuations and other climate factors can have a significant impact on the service life of a roadway’s markings, sometimes reducing the paint’s performance by years and increasing maintenance needs beyond what a transportation agency had originally budgeted.
To find ways to improve the markings’ performance, Arizona DOT investigated the successful practices of other agencies facing similar challenges in comparably diverse conditions. The research led to a variety of recommendations to help pavement markings last longer.
