The ACPA Board took several important actions during its third quarter meeting in Rosemont on October 11. The board affirmed its support of the advancement of a new promotion plan developed jointly with Portland Cement Association. The plan is currently being refined and will be discussed with the Portland Cement Association Board later this month.
The ACPA Board also provisionally accepted a 2019 draft budget plan prepared by the Budget & Finance Committee, with the understanding that outstanding questions will be clarified between now and the annual meeting on Nov. 27-29. Adjustments may be made as needed during the interim period, with final acceptance anticipated at the next board of directors meeting Nov. 29. The Association anticipates a budget of $3.88 million to support pavement promotion.
In addition, directors affirmed the Association’s support of the CP Tech Center’s efforts on the performance engineered mixtures (PEM) research/development program and considered a new proposal from the Aggregate & Ready Mix Association of Minnesota to formalize a chapter affiliation agreement, supporting pavement promotion in the state.

“Using Recycled Concrete Aggregate in Pavement Base Products,” is the latest MAP* Brief released by the CP Tech Center.
The introduction describes how RCA is used widely as a base material, in part because its performance can meet or exceed that of natural aggregate. This 8-page document describes construction considerations, qualification testing, and pavement design considerations for both unbound and bound (or stabilized) RCA base. It also highlights environmental factors to look for, as well as well as related environmental benefits.
Written by Mark Snyder, Pavement Engineering and Research Consultants, LLC,** this MAP Brief also includes covers several example problems that provide some interesting and useful details, valuable information to agencies, consultants, and contractors working with RCA as a viable concrete pavement base.
