An Ammann AP 240 Pneumatic Tyred Roller helped a Kenyan company compact a thick asphalt layer while also meeting targets for density and timeliness at Kisumu International Airport in Kisumu, Kenya.
“The AP 240 can be used to compact asphalt layers up to 150 mm layer thick when ballasted to the proper weight,” said Nayim Shah, director of Pride Enterprises. “With that weight, we can achieve the required strength.”
Adding the ballast was effortless, Shah said. “We ballasted it ourselves,” he said. “It was a very simple process.”
The 150-mm surface lift at the airport was tested, and results confirmed the AP 240 achieved its compaction density targets.
Density wasn’t the only goal. As with all airport projects, time was at a premium, and the compaction work needed to be done during the facility’s least busy times. “We were working overnight, and with the new AP 240, we were not worried about any breakdowns,” Shah said.
He noted that operators found the machine easy to control. “It is very user friendly – a simple machine to operate,” Shah said. Operators also appreciated the consistency of the braking system and the quiet, spacious cab.
Shah likes the low cost of ownership and the ease of maintenance. “The machine currently has 332 hours and we have only done one servicing,” Shah said. “There have been no other expenses associated with it.”
