Clear Roads Research Featured at Environmental Conference November 23, 2022

On October 13, 2022, members of the Lake George Association in upstate New York hosted their annual Salt Summit to discuss strategies and technologies for reducing road salt. Clear Roads member Joe Thompson of New York State DOT spoke at the event, sharing highlights of the in-progress Clear Roads research project investigating ways agencies can improve their winter maintenance operations to recognize environmentally sensitive road segments.

New Clear Roads Research: Understanding the Chemistry of Road Salt October 26, 2022

As temperatures drop, sodium chloride loses its deicing power. Depending on conditions, adding more salt to a roadway may be ineffective and wasteful.

To help maintenance managers make the most of their stockpiles and keep roads clear, this Clear Roads research project investigated how salt behaves at different temperatures and concentrations. With a new tool and other educational materials from Clear Roads, practitioners can better understand how and when to apply sodium chloride for best results.

AASHTO Targets Deicing Materials with New Lab Proficiency Testing Program September 16, 2022

Does your organization have a laboratory that tests deicing products? AASHTO re:source is looking for you!

Clear Roads is partnering with AASHTO re:source to help laboratories improve and standardize their testing protocols for winter materials used for anti-icing/deicing applications.

Through its new Proficiency Testing Program, AASHTO re:source is helping to improve the quality of test standards, materials, and technician competency at labs that evaluate solid and liquid deicing products. Once a year, AASHTO re:source provides participating laboratories with product samples to test and then scores the labs on their testing performance.

The Proficiency Testing Program is available at no cost for AASHTO member departments; the cost is $275 per year for other participating laboratories.

New Hampshire and Iowa Recognized for High-Value Winter Research August 31, 2022

New Hampshire DOT’s study of LED snowplow lights and Iowa DOT’s investigation of self-heating electrically conductive concrete recently captured national attention as two of AASHTO’s High Value Research winners for 2022. The award recognizes the nation’s top high-value research projects as chosen by state DOT research directors in each of the four AASHTO regions.

In New Hampshire, an in-house project quantified the benefits of LED plow headlights compared with traditional halogen bulbs. The study found that the LED headlights improved operator visibility and reduced eye fatigue, and a cost-benefit analysis showed that the lights’ lower maintenance requirements led to significant cost savings compared with halogen bulbs.

In Iowa, a three-year demonstration project evaluated the performance of an electrically heated concrete system that incorporates conductive carbon fibers within the concrete mix. The concrete, which can melt snow and ice without the use of deicers, could one day be a sustainable option for icy trouble spots that are not easily cleared during winter storms.

The two projects were honored last month at the annual AASHTO Research Advisory Committee meeting. For more on these award-winning projects:

Congratulations to all the High Value Research winners!

Clear Roads CDL Training Materials Featured in APWA Reporter August 22, 2022

Clear Roads’ popular commercial driver’s license (CDL) training materials are in the news. An article in the August issue of APWA Reporter spotlights how agencies are using the comprehensive, step-by-step training program, which is designed to help agencies comply with new federal regulations as they train equipment operators who need to obtain or upgrade a CDL.

The free training program provides a complete curriculum for the classroom and behind-the-wheel components of CDL training, including eLearning files for use with learning management systems. Train-the-trainer resources and process guidance are provided to help agencies implement the program.

No Boundaries Report Identifies Strategies to Recruit and Retain Workers August 4, 2022

Workforce shortages are a top concern for transportation agencies across the country. With maintenance workers needed year-round to keep roads clear and safe, the No Boundaries Transportation Maintenance Innovations pooled fund program has published a new report designed to help agencies identify recruitment and retention challenges and uncover noteworthy and effective solutions.

The recently published report, No Boundaries Synthesis: Responses to Staffing Shortages, documents strategies such as apprenticeship programs that provide on-the-job training, creative outreach efforts, innovative compensation and benefits packages, and more.

In addition, the report addresses the new federal commercial driver’s license requirements, their effect on the pool of qualified applicants nationwide, and how agencies are responding.
