WHEN AND WHERE

The workshop will be held October 24-26 at the Vib Hotel by Best Western Denver RiNo located at 3560 Brighton Boulevard, Denver, Colorado.

WHO SHOULD ATTEND

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.

EVENT REGISTRATION

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.

Group Discussion Focuses on Solutions

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.

The lecture will discuss, why do we write specifications, what we want from them, how do we know got what we want, and the philosophy of testing.

2:30 PM – 2:45 PM – BREAK

2:45 PM – 3:30 PM – Insights on Portland Limestone Cement (PLC) & Concrete mixtures (Anne Miller, Quality Manager – GCC of America - Pueblo Plant) (invited)

With the recent change to PLC use nationwide, the obvious question is whether a correlation exists between the newer cement type and performance issues. A significant history now exists of using PLC for concrete pavements on DOT, local agency, and airfield projects. This presentation identifies the importance of re-evaluating mix designs to verify that material combinations are compatible and provides strategies for developing and batching concrete mixes when utilizing new material combinations.

3:30 PM – 4:15 PM – Portland Limestone Cement in Airfield Pavements (Dr. Peter Taylor, Director of the Concrete Pavement Technology Center (CP Tech Center) and Airport Concrete Pavement Technology Program (ACPTP))

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.

4:15 PM – 4:45 PM – Mix Design requirements for Airfield Paving (Matt Fonte, Fonte and Company)

There are many misunderstandings pertaining to the airfield concrete pavement requirements for mix design constituents and processes to meet the requirements of 32 1314.13 and P-501. Airfield paving concrete requirements are more rigorous than for other applications. This lesson will present the process and what is required for the mixture design submittal to meet the 32 13 14.13 and P-501 requirements as defined by TSPWG M 3-250-04.97-05 Proportioning Concrete Mixtures with Graded Aggregates for Rigid Airfield Pavements.
