May 24, 2010

The National Stone, Sand & Gravel Association (NSSGA) in conjunction with the Aggregates Foundation for Technology, Research and Education (AFTRE) are hosting an “Inverted Pavement Systems” Webinar to be held on Tuesday, June 1 from 11 a.m. ET to noon ET.

Inverted pavement systems take advantage of the structural integrity of the aggregate base layer which is sandwiched between an asphalt pavement layer (above) and a cement treated base layer (below).

Industry representatives will talk about the advantages of this system and the results of investigations sponsored by AFTRE.

Webinar presenters are Shane Buchanan, Ph.D., P.E., senior materials engineer with Vulcan Materials Company, Birmingham, Alabama and Randy L. Weingart, P.E., director, quality management & product research, Luck Stone Corporation, Richmond, Virginia.

AFTRE has sponsored research on inverted pavement systems in conjunction with the Georgia Department of Transportation at Georgia Tech University.

Design technology developed through the International Center for Aggregates Research (ICAR) has been applied to designing inverted pavement systems and continues to be developed.

The inverted pavement system has been used effectively in other countries for several decades and was recommended for consideration in North America by an FHWA Technology Scan Tour conducted several years ago.

The webinar will overview the components of the system, its performance history and the status of current AFTRE research on the system. The intended audience includes aggregate company executives, marketing, sales and production personnel.

This is the first in a series of webinars being developed through AFTRE as a means of educating aggregate industry representatives.
