Evaluating CMAQ Projects in Terms of Cost Effectiveness, Performance Measures, and Multi-pollutant Benefits

By ahardingMay 7, 2021Leave a comment

The Congestion Management and Air Quality Improvement Program (CMAQ) has existed since 1991 providing benefits by reducing air pollution. This program has evolved over the years and will be entering…

Optimizing and Streamlining Data Collection and Analysis for Project Level Air Quality Modeling

By ahardingMay 7, 2021Leave a comment

State DOTs would benefit from guidance that goes beyond the norm on how to conduct modeling for project-level air quality analyses and addresses which modeling inputs are the most cost-effective…

Novel Deicing Material Evaluation for Roadways and Bridges

By ahardingMay 7, 2021Leave a comment

Traditionally, the main priority of winter road maintenance has been assigned to level of service, cost-effectiveness, and infrastructure corrosion rather than other less well-characterized effects such as impacts to water…

Context Sensitive Design Options for Rural Workhorse Bridges in Historic Districts

By ahardingMay 7, 2021Leave a comment

In most states, commitment to put a context-sensitive bridge in as a replacement for a historic bridge in a historic district is made without reference to known examples, design and…

Developing a testing protocol for new rivets in a rehabilitated metal bridge

By ahardingMay 7, 2021Leave a comment

Compliance Measures for Managing Chloride-Based Deicers

By ahardingMay 7, 2021Leave a comment

Chloride-based deicers continue to be the primary deicing chemical of choice due to the huge cost differential with non-chloride deicers. Essentially there are no salt alternatives that are comparable in…

Highway Crossings for Wildlife

By ahardingMay 7, 2021Leave a comment

There is a great interest in safe wildlife crossings for a number of reasons: reduced auto/animal collisions that cause economic loss, and physical harm or death to humans and animals.…

Methodology for analyzing noise impacts on different terrestrial species

By ahardingMay 7, 2021Leave a comment

Develop a consistent methodology for analyzing noise impacts on different terrestrial species. Develop standard metrics and procedures for the DOTs to conduct noise analyses of our highway projects on wildlife,…

Design, Build, Operate and Maintain (DBOM) Contracting

By ahardingMay 7, 2021Leave a comment

The US interstate highway system is essentially complete, and was constructed in large part without the benefit of stormwater quality features to improve highway runoff water quality or measures to…
