The American Concrete Pavement Association will present a three-day national workshop on best practices used in the design, construction, and rehabilitation of concrete pavements used for airport applications.
The workshop program will feature technical presentations by subject matter experts with practical experience in the topic areas. Leading the discussions will be experts from the U.S. Army Corps of Engineer’s Transportation System Center, the FAA Headquarters Office of Airport Safety and Standards, Air Force Civil Engineering Center, ACPA, and companies with direct involvement in the design and construction of FAA and Tri-Services projects.
The workshop will be held October 24-26 at the Vib Hotel by Best Western Denver RiNo located at 3560 Brighton Boulevard, Denver, Colorado.
The workshop is intended for owners’ representatives, design engineers, contractor personnel, and others with an interest in concrete pavement design, construction, and rehabilitation for airport applications.
The cost of the three-day workshop is $900 for members and government employees, and $1,200 for non–members. Register online using the form at the bottom of this page.
A popular element of ACPA’s airport pavement training program is open discussions about interpreting and applying airport concrete pavement specifications used by the Federal Aviation Administration (FAA) P–501 and Unified Facilities Guide Specification (UFGS) 32 13 14.13 specifications.
This group discussion serves as a guide for interpreting, gaining a better understanding, and gaining practical insights about the specifications.
The discussion will be based on field experience and guidance from top pavement experts. Much of this information has been gained by working with contractors, owner’s representatives, military engineers, and others with direct, first-hand experience. The discussion is not intended as a basic primer on the specifications; instead, it will cover details of specification-related issues, challenges, and questions that commonly occur on the grade.
Participants may earn up to 20 professional development hours for this training and technology transfer event. ACPA offers professional development hours with the assumption of their use in self-reporting states and provinces. Reporting is done on an honor basis, and participants are responsible for maintaining their own records and for determining the applicability and acceptance with their respective licensing/certification organization. Check with your licenses agency to confirm acceptance of this workshop for meeting PDH requirements.

Cement companies across the country have shifted from manufacturing Type I/II cement to predominantly Type IL, or Portland Limestone Cement (PLC). While the cements are very similar, there are important differences that need to be acknowledged when developing mix designs and producing concrete. This lesson discusses how different cement characteristics affect properties of fresh and hardened concrete and what strategies can be utilized to achieve the desired properties for airfield concrete pavements.
