SCAPA News and Events
  
The SCAPA Staff and Board of Directors look forward to connecting with many of our members at the 2022 SCAPA Summer Conference in Charleston next weekend! The Conference is being held at The Charleston Place from June 23-26 for the Board of Directors and June 24-26 for SCAPA Members. 
  
We want to recognize all of our SCAPA Summer Conference Sponsors for your continued support -- because of you, we can continue to put on quality events. Be sure to thank the representatives from each of our Sponsor organizations when you see them.
  
The Asphalt Pavement Alliance (APA) recently announced that the South Carolina Department of Transportation (SCDOT) has won a 2021 Perpetual Pavement Award (PPA): By Performance for a 4-mile section of four-lane divided Interstate 95 from mile marker 0 to mile marker 4 in Jasper County that is more than 45 years old. SCDOT has earned 10 PPAs: By Performance since the program began in 2001.
  
SCAPA Associate Member Training on Compensation Strategies, presented by DHG's Mark Deverges, was very well attended and received by SCAPA members and other industry professionals. See the highlights here and...

SCAPA Associate Members: Consider providing a presentation for the SCAPA Associate Member Training Series. This is a monthly program wherein one SCAPA Associate member will partner with SCAPA to organize a virtual educational event for SCAPA membership and industry partners. Please fill out the included form to submit your presentation.

In this article titled “Development of a Framework for Balanced Mix Design,” the authors discuss the Superpave asphalt mix design system and its purpose. It was envisioned to include three levels (Level I-III) based on the design traffic for the pavement. Level I was envisioned to be for low-traffic pavements and the mix design requirements would be primarily based on traditional volumetric properties. Level II would be used for the majority of projects that carry moderate traffic levels and would include volumetric requirements plus a limited set of mixture performance tests. Level III would be for high-traffic pavements and would also start with a volumetric based mix design followed by an expanded set of advanced performance tests. However, the “performance tests” were never implemented except for a few special projects, primarily because the tests were not considered practical for routine use for the thousands of mix designs used each year in the United States.
Time: Tuesday, July 26, 2022; 2:00 PM to 3:30 PM EDT
Speakers: Raven Adams, Sustainability Specialist, Granite Construction Inc.; Heather Dylla, PhD, Vice President of Sustainability and Innovation, Construction Partners Inc.; and Milena Rangelov, PhD, Research Engineer, Federal Highway Administration
Description: Increasingly, paving contractors are being asked by stakeholders to quantify the greenhouse gas (GHG) emissions associated with their operations. This may come in the form of demand from shareholders for corporate GHG emissions reporting, customer requirements for environmental product declarations, or internal initiatives for process improvement to achieve emission reduction goals. Various tools exist that allow organizations to quantify GHG emissions, each of which has its own methodology, scope, and system boundaries. This webinar will explore the various tools and approaches that organizations use quantify GHG emissions associated with asphalt pavements, ranging from direct emissions associated with operations to cradle-to-grave life cycle assessments (LCAs).
  
The 2022 SCDOT certification course schedule has been released. Online registration is available on TCTC's website at www.tctc.edu/scdot.
The site will have only one of each course type available for registration at a time, so not all of the sections will show as available. 
Asphalt Facts
ONE OF THE MOST COST-EFFECTIVE WAYS TO REHABILITATE A WORN-OUT CONCRETE HIGHWAY IS TO RUBBLIZE IT, THEN OVERLAY IT WITH ASPHALT.

In Arkansas, 276 miles of concrete interstates were given new life in a rubblize-and-overlay program. Rubblization makes the base into an interlocked matrix of pieces as the concrete breaks up. The asphalt overlay can even turn a failed concrete pavement into a Perpetual Pavement.
