“The 3D paver placed the P209 crushed aggregate base course, paved the airstrip and passed the straight-edge test without any remedial work required,” Harrigfeld said. “It’s not a common practice to lay gravel with a paver because it’s extremely abrasive. I had never done it before so I was worried about the amount of wear we would have on the paver. As it turns out, the amount of wear was minimal compared to the amount of time we saved and still met the critical tolerances that the system allowed us to have.”
In addition to meeting tight tolerances, using the Trimble PCS900 allowed Harrigfield to complete paving operations in a shorter time frame - in 17 days instead of the at least 25 days he estimated it would have taken without 3D paving technology.
“The Trimble technology on the paver helped us in the race to not only meet the county’s deadline for completing the Miley Memorial Field Airport airstrip rehab but also beat the weather coming in for the season. Two or three days after we completed the job, we had an eight- to 10-inch snowfall that would have shut that job down for the year," Harrigfeld said. "During our crunch to get everything completed we had tremendous support from our local Trimble dealer who helped get everything set up on the paver and was on site monitoring the progress. I’m happy with the work our crew did and the cooperation we received from our dealer. I’m proud of the results and would have no hesitation ever flying into that airport.”
