ACPA and FHWA Discuss Life-Cycle Cost Analysis
- Tuesday, 01 May 2018 08:56
ACPA’s 2nd Vice Chairman Jim Mack (CEMEX) and Leif Wathne met with FHWA officials last week to discuss Life Cycle Cost Analysis (LCCA).
Representing FHWA were LaToya Johnson, FHWA Team Leader–Pavement Design and Performance; Gina Ahlstrom, Team Leader–Pavement Materials; and Heather Dylla–Sustainability Program Manager.
FHWA is working on updating their LCCA guidance and expects to request stakeholder input, which will be announced in the Federal Register. ACPA and the concrete pavement industry will continue to stay actively engaged with FHWA as a reliable and credible resource for industry perspectives on LCCA. We anticipate knowing more about FHWA’s timeline for publishing their guidance later this spring, Wathne says.
ACPA Releases Two Joint Sealing/Filling Tech Documents
- Tuesday, 01 May 2018 07:45
ACPA has released “Concrete Pavement Joint Sealing/Filling,” a comprehensive new technical bulletin that provides practical information on the range of options available to seal and fill joints, including considerations of leaving joints open.
Developed by the ACPA Jointing Task Force, the 24-page bulletin provides industry standards, practical recommendations, tables, and color illustrations, all of which reflect up-to-date, useful information for engineers and contractors.
“Anyone who specifies and works with concrete pavements is encouraged to review the recommendations in this bulletin as a starting point to reassess their joint sealing/filling practices,” says ACPA’s Jerry Voigt. “Unless local experiences indicate that sealing or filling provides limited performance protection value, the recommended practice is to seal and maintain joints paying careful attention to reservoir design, sealant installation and maintenance requirements.”
New details for reservoir dimensioning for effective cleaning and installation of both formed-in-place and compression seals are included in the document, as are step-by-step recommendations for sealant installation, including reservoir cutting and preparation; sealant installation; and quality control (QC) checks.

A companion document, “Joint Reservoir Quality Control Wipe Test,” was also released by ACPA. The wipe test is an effective means of capturing the relative amount of concrete dust, dried saw slurry, and other contaminants found on the joint reservoir walls and bottom. The document includes required equipment, materials, procedures and suggested documentation to perform the QC test.

Pavement Preservation is Focus of Peer Exchange
- Tuesday, 24 April 2018 14:58
The FHWA Peer Exchange project, working with the CP Tech Center, held its first pavement preservation meeting during NACE on April 22.
More than 60 NACE participants signed up for a discussion about key preservation strategies and issues, says Larry Scofield.
Scheduled for 2018 and 2019, these peer exchanges are intended to raise awareness and provide practical knowledge to practitioners. This will also complement contractor training on preservation, currently in final production. ACPA led the development of the training under agreement with the CP Tech Center.
