The staff of Asphalt Contractor recently attended the Asphalt Recycling & Reclaiming Association’s (ARRA) In-Place Recycling and Reclaiming Seminar in August in Lake Geneva, WI.
The In-Place Recycling & Reclaiming Seminar, with a live demonstration, is designed as a forum for pavement professionals representing state, local and federal agencies, contractors, suppliers, consultants, academia, and MPOs, all working together to take advantage of the synergy to be gained from sharing information and identifying common issues for further investigation.
The seminar provided a platform for national pavement professionals to present the state-of-the-art technologies that went on to be the building blocks of the Basic Asphalt Recycling Manual (BARM).

A look at each process

During the conference, representatives from each ARRA discipline, including hot in-place recycling, thin pavement techniques, cold in-place recycling, full-depth reclamation and soil stabilization, gave an overview of each process, what type of equipment is used and at what point in the pavement lifecycle each process is best suited.
There was also a look at industry trends, including intelligent compaction, GPS control and aerial survey, that can help both agencies and contractors get the best results out of their pavements.
Representatives included Rock Solid Stabilization & Reclamation, Gallagher Asphalt, Roadtec, Midstate Companies, Cat Paving, Topcon and more.

Live demos

The live demonstration attended by the staff of Asphalt Contractor included several different types of full-depth reclamation (FDR) and soil stabilization techniques.
On a 3,000-foot section of Klemman Road near Hebron, IL, just south of the Illinois-Wisconsin border, the Rock Solid Stabilization & Reclamation crew demonstrated 4- and 8-inch FDR with oil emulsion, 12-in stabilization with cement, and a 12-in. stabilization with Jolena, a fly ash/cement combination.
Attendees got to see how the process was performed step-by-step, get an up close look at the equipment and materials in action, ask questions and network with their peers.
Jonathan Pease, president of Rock Solid Stabilization & Reclamation Inc., headquartered in Genoa City, WI, helped coordinate both the In-Place Recycling Seminar and live demo in Lake Geneva, as well as one held the week prior in Fargo, ND, which included live demonstrations of several types of processes.
“This conference is really designed as a collaborative effort between the ARRA association members and equipment suppliers to help promote these techniques to state and local agencies,” says Pease. “It’s crucial for them to understand all the tools available for making their pavements last. It also saves taxpayer money if the right process is used at the right time in the pavement’s lifecycle.”
