A new process for delivery of highway projects is developed in Critical Path for Project Development , a report from the Kentucky Transportation Cabinet. The goal of this report is to assist project managers and consultants in pursuing project management in an organized, orderly, and intuitive manner.

Factors affecting a bridge’s durability are examined in Performance of Bridge Deck Overlays in Virginia: Phase II: Service Life Performance , a report from the Virginia Department of Transportation. This report focuses on bridge deck overlays and develops a model for understanding how long these overlays last without rehabilitation.

The general durability of hybrid composite beams (HCBs) is determined in a report from the Virginia Department of Transportation. The ability to inspect and ensure the durability of HCBs is important for transportation construction projects.

Design criteria of bridge beams prestressed with carbon fiber reinforced polymer (CFRP) strands are established in a report from the Michigan Department of Transportation. This report evaluates CFRP design parameters such as maximum tensile strength, guaranteed strength, environmental reduction factors, relaxation, creep rupture strength, short and long-term prestress loss, and performance at elevated temperatures.

New electronic project design and delivery methods are explored in a report from the Minnesota Department of Transportation. This report discusses the complete transformation of transportation projects in Minnesota to smart, paperless, 3D electronic delivery and identifies the potential challenges of this transformation.

Laser ablation coating removal is discussed in Innovative Coating Removal Techniques for Coated Bridge Steel , a report from the Virginia Department of Transportation (VDOT). This report determines whether laser ablation is an acceptable alternative for removing existing coatings.

Using geosynthetics to reinforce pavements is examined in Accelerated Load Testing of Geosynthetic Base Reinforced/Stabilized Unpaved and Pavement Test Sections , a report from the Louisiana Department of Transportation and Development. Specifically, this report evaluates the benefits of using geosynthetics to reinforce or stabilize base aggregate layer and subgrade in pavements under repeated loading test conditions.

The complexities of connected vehicles are addressed in How Locals Need to Prepare for the Future of V2V/V2I Connected Vehicles , a report from the Minnesota Department of Transportation. This report discusses the connected/automated vehicle (CAV) ecosystem and its background, potential CAV applications, and types of communication and hardware required for CAV systems.

How scanning technology is used to document existing facilities is explored in 360-Degree Point Cloud Technology for Building Management , a research synthesis from the Minnesota Department of Transportation. This report reviewed the existing state of technologies and identified possible solutions to implement into transportation project workflows.

Roadside ditches enhanced with iron are examined in Iron-Enhanced Swale Ditch Checks for Phosphorus Retention , a report from the Minnesota Department of Transportation. Iron-enhanced ditches may improve net phosphate retention through roadside swales.
