Make Plans to Attend ACPA’s 52nd Annual Meeting

HyattRegencyCoconutPoint-BonitaSprings-FL-panview-webACPA is putting the finishing touches on the program for the Association’s 52nd Annual Meeting, which will be held December 1st through 4th at the Hyatt Regency Coconut Point Resort & Spa in Bonita Springs, Fla. The Association is urging members, affiliates, and guests to make plans to attend the meeting.

Earlier this year, ACPA conducted a survey about the annual meeting, and will be incorporating many of the following suggestions into the program:

  • Greater contractor attendance and participation.
  • More quality and less quantity for the Concrete Pavement University (education & training tracks).
  • More technical topics and fewer promoter-oriented topics.
  • A half-day session for contractors to share best practices and innovative ideas.
  • Fewer optional activities (but a continuation of the receptions).

Survey respondents also asked ACPA to modify the golf outing to make it faster to play. Also, for the awards banquet, respondents said to keep the existing format (where winners are notified in advance, but the news of “gold” or “silver” levels are not revealed until the banquet).   

ACPA will be announcing additional details soon, and in the interim is urging everyone to “save the dates” for the annual meeting.

ACPA to Host Airport Pavement Workshop in Texas

ACPA is encouraging members, Chapter/State affiliates, and other interested parties to make plans to participate in ACPA’s Airport Pavement Workshop, scheduled for November 3 through 5, in Austin, Texas.

This comprehensive training, led by ACPA’s Gary Mitchell and other leading subject matter experts, will cover airport pavement design, construction, and rehabilitation.   The course will also include detailed information about interpreting and applying airport concrete pavement specifications used by the Federal Aviation Administration (FAA) and Unified Facilities Criteria (UFC). 

The workshop will be held at the Hilton Austin Airport Hotel, 9515 Hotel Drive, Austin.   Additional information will be sent to ACPA members, Chapter/States, airport owners’ representatives, engineers, and others involved in the design and construction of airport concrete pavements.

 ACPA Announces Joint Design & Construction Workshop

ConcretePavementJointDesignandConstruction-smACPA will present a two-day national workshop on concrete pavement joint design and construction, as well as the closely related subjects of load transfer, tie bar systems, and dowel alignment.

Scheduled for Tuesday and Wednesday, October 27 and 28, the workshop will be held in the third-floor conference room at ACPA’s Rosemont, Ill. headquarters office. The program will be held from 10 a.m. to 5 p.m. (CDT) the first day, and from 8 a.m. to 3 p.m. (CDT) the second day.
