“Ideally, you want to keep moving,” says Koppelmann. “We were able to work fast enough that there was no worry of cold joints or damage from the roller sitting too long in one spot.” Koppelmann indicated a new dump truck would show up with a load every 15 minutes.
The heavy equipment they had to carefully maneuver down this tiny 12-ft. wide path? A Dynapac 90 Dirt/Stone Roller, Caterpillar Backhoe 420F, CAT Grader 140G, CAT Excavator 312 and CAT Roller CB-24, along with a Roadtec Paver RP-150. Through diligence of the crew, they were able to accomplish the goal of minimally disrupting the area around the path that was being constructed.
The asphalt mix E&B used was selected by the designer and Indiana Department of Transportation. The asphalt was placed on a 6-in. base of 53 stone. Approximately 790 tons of an intermediate mix was used for the entire project, followed by 460 tons of an HMA surface mix. The trail was 2-in. of intermediate and 1 ¼-in. of surface. The parking lot was 4 ½-in. of intermediate and 1 ½-in of surface.
E&B also re-graded and enlarged the stone boat ramp and parking lot. By readjusting the grades and double checking elevations, they were able to ensure the new pavement would fall in the right direction. This helps extend the life of the ramp as a proper grade allows water to drain adequately so there will be no standing water. The parking lot was increased by more than 55 sq. ft. and the boat ramp now measures 45 ft. x 55 ft., up from the initial 30 ft. x 30 ft.
Koppelmann indicated they stayed on schedule, despite the setbacks, by making sure they had a full days’ worth of work available to place asphalt. “There was a true partnership between the city of Wabash, the engineering and consulting firm and us to keep this project moving at a steady pace and to keep the project as cost efficient as possible for the city,” Koppelmann says.
The project, which finished in June 2012, received a National Asphalt Pavement Association (NAPA) Quality in Construction Award for 2012. “We take pride in winning those awards,” adds Koppelmann. “We try to do our best to instill quality in all our crews out in the field.”
