Feasibility of Cold Central Plant Recycling (CCPR) Asphalt Mixtures for Airports

With the Administration setting the goal that the United States will be carbon neutral by 2050, all industries are being asked to consider how they can contribute to making this goal reality. Recently, Cold Central Plant Recycling (CCPR) has been used by some agencies to reduce energy demands and research has suggested that CCPR mixtures can perform well on highways; however, little research has been conducted to show the feasibility for this type of mixture on airfields. The objective of this project is to assess the feasibility and potential benefits of using CCPR asphalt mixtures at all categories of airports.

Mitigation of Plastic Flow and Delamination at High-Speed Exits

While high-speed exit taxiways are critical, for decades they have been the source of pavement distress due to the significant stresses placed on flexible pavements as heavy aircraft are turning at high speeds. This project focuses on understanding the mechanisms causing the failures at high-speed exits and finding solutions to prevent them through either construction or materials specifications.

Improving Performance of Longitudinal Joints in Airfield Asphalt Pavements

Two of the biggest observed performance issues on airport asphalt pavements are cracking and raveling at longitudinal joints often related to insufficient density of the asphalt mixture in the joints. This project focuses on best practices currently used to maintain longitudinal joint performance and an evaluation of new technologies that could also extend joint life.

Asphalt Mixtures Paving Handbook Revision

In 2000, the Transportation Research Board updated the Hot-Mix Asphalt Paving Handbook. In the decades since its publication, new technology has become available that can aid in ensuring high quality asphalt pavements are constructed for highways or airfields. The book revision will include the latest technologies and best practices for highway and airfield paving.
