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.

Submission Deadline is closed.

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 aircrafts 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.

Submission Deadline is closed.

Improving Performance of Longitudinal Joints in Airfield Asphalt Pavements

Two of the biggest observed performance issues on airport asphalt pavements is 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 which could also extend joint life.

Balanced Mix Design - Rutting

Evaluation of Balanced Mix Design for airfield pavements will be undertaken in two separate contracts. The first of two Balanced Mix Design projects will focus on harmonizing the rutting requirements in the current FAA specifications.

Submission Deadline Closed


Balanced Mix Design - Cracking 

The second Balanced Mix Design project explores which cracking tests should be considered for airfield evaluation. In coordination with the rutting project, the framework and draft specifications for a Balanced Mix Design process for airfield pavements will be achieved.

Asphalt Mixtures Paving Handbook – 2022 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 which 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. 

Submission Deadline Closed

Binder Grade Selection

To aid engineers in selecting the proper binder for asphalt mixtures at airfields, this project will develop guidance and an app which simplifies the decision making process to ensure that individual project requirements are in compliance with current airfield specifications.
