During its 30th Annual Meeting in Palm Springs, Calif., in February, the Asphalt Recycling & Reclaiming Association (ARRA) announced the recipients of its Annual Awards for Excellence, given this year to two public officials in two of the technical disciplines represented by the organization.
ARRA’s 2006 winners by category are: Joseph F. Peterson, P.E., Excellence in Full Depth Reclamation, District Materials Engineer, North Region California Department; and Joe Schroer, Charles R. Valentine Award for Excellence in Cold In-Place Recycling, field materials engineer, Central Materials Lab.
During the last three years, Peterson has promoted and educated within Caltrans the benefits of recycling and reclamation. In 2005, because of his efforts, three cold-foam full-depth reclamation (FDR) projects were completed by Caltrans along with two other projects entering the design phase. Peterson served as the design engineer and as Caltrans quality-control advisor on all of these projects. Peterson also was the writer of the original cold-foam FDR specification within Caltrans and conducts all the reclamation and recycling training within Caltrans, currently having completed training within six of the 12 districts.
Peterson served as the original design engineer and acted as the state’s consultant and quality-control representative in 2005 on the San Luis Obispo County/Santa Barbara County Highway 33 job, a cold-foam in-place recycling project involving several grade and material changes throughout. The shoulders were recycled contiguously with the mainline using two staggered foaming reclaimers.
The Valentine Award involved Highway 71 in northwest Missouri. In the recent past, if you were visiting Northwest Missouri State or taking a break at Mozingo Lake, you may have traveled on the four-lane route of Highway 71. As you headed north from St. Joseph you may have noticed that the asphalt pavement you were driving on was in need of rehabilitation. Well, so did District 1 of the Missouri Department of Transportation (MoDOT). But with MoDOT dollars being very limited, they decided to look for other ways to reconstruct this stretch that would allow them to cover more miles with fewer dollars. That is where the idea of CIR and FDR came into play.
CIR was done on the main driving lanes and FDR on the shoulders.
Brown and Brown began the shoulder work in June 2005 with its CMI RS-650 to reclaim 4 in. of base and 2 in. of hot-mix asphalt.
Once the shoulder work was completed, Brown and Brown addressed the main driving lanes using lime slurry and SemMaterials engineered emulsion to recycle the existing 4 in. Herzog finished the project with a 1.75-in. Superpave hot mix.
ARRA elected Tom Johnson to the office of president for the 2006-07 term. As president of MidState Reclamation Inc., Lakeville, Minn., he is involved in FDR, CIR, cold milling and soil stabilization/modification. Johnson has served as vice president and secretary-treasurer and as program chairman and chairman of ARRA’s Technical Subcommittee on Full Depth Reclamation.
Other 2006-07 officers elected were: vice president Greg Brown, Brown & Brown Inc.; and secretary/treasurer Dave Cannon, Cutting Edge Reclamation LLC. ARRA’s immediate past president is Stephen Damp of Miller Paving Inc. in Ontario, Canada.
