ACPA Presents Concrete Pavement Jointing Training
- Wednesday, 06 May 2020 10:34
ACPA partnered with the Florida Chapter to present an hour-long training session for Florida DOT officials, engineers, consultants and others with an interest in quality concrete pavement construction.
The webinar focused on concrete pavement jointing, with Eric Ferrebee and Mark Snyder each presenting information to close to 60 professionals.
Eric covered topics such as why we joint concrete pavements, types of joints, joint spacing and aspect ratio, and joint layout for intersections. Mark covered dowel and tie-bar design considerations, construction details and joint construction consideration.
Technical resources and other information, including access to existing recorded webinars were also provided to attendees. This session and the resources offered were provided as a substitute for in-person workshops, which because of COVID-19, were no longer feasible.
At the end of the webinar Eric and Mark offered a Q&A session, which lasted close to 30 minutes. ACPA and the Florida Chapter are tentatively planning in-person training on the topic later this year.
Professors’ Seminar to be Recast
- Monday, 04 May 2020 13:28
ACI announced late last week the in-person Professors’ Seminar will not be held this year, but is expected to return to ACI Headquarters in the summer of 2021.
Organizers are currently exploring options to deliver the workshop effectively in a virtual format that addresses the unique needs of the current environment, according to ACI.
The Professors’ Seminar is a long-standing training program that provides university professors with training, educational resources for students, and information that can easily be adapted and used as formal university curricula. ACPA supports the program with subject matter experts and free resources for professors and students. Look for additional details in a future issue of ACPA TODAY.
Weather Channel Spotlights Pavement Resilience Remarks by Jim Mack
- Thursday, 30 April 2020 01:09
In an interview on the Weather Channel last Friday, Jim Mack presented some balanced perspectives on pavement resilience. Jim is Director of Market Development at CEMEX* and past Chairman of the ACPA Board.
“For the most part, both asphalt and concrete roadways can be made more resilient and flood resistant,” he tells host Weather Underground Mark Elliott and other staff meteorologists.
“But concrete, just by its very nature, is a little bit more naturally flood resistant just by the stiffness of the system,” he continues.
Jim describes two types of flooding damage. “Washout is where running water comes along and washes out the ground,” he says, adding that both rigid and flexible pavements are both susceptible to this damage.
He also describes inundation as “the silent killer,” adding that this is where rising waters, as are often seen in aerial views, soak the base and the ground under the pavement.
“This can lead to the long-term deterioration of a pavement that’s not as stiff as other pavements, such as concrete,” he says.
The almost 3-1/2 minute interview included other facts and examples, as well as video footage of flooded pavements. Click here to see the complete interview.
