Here is how Shirey set up the paving configuration to get both good production and pavement smoothness. Forty-four tandem and tri-axel dump trucks were required to keep paving continuously. At the fore of the train was the Shuttle Buggy followed by a Caterpillar paver. Next, each paving train included two new Ingersoll-Rand DD118 HF vibratory compactors for breakdown followed by two DD90HF vibratory compactors for intermediate compaction. Lastly, there was DD110 vibratory compactor used in the static mode for finishing.
Shirey says his company is considering purchasing two new Roadtec Stealth pavers to replace the old pavers. If this is done, the company will either rent a second Shuttle Buggy from Hawbaker or purchase one to round out the paving trains.
Contractors not owning an MTV should consider bidding on projects requiring one if the work looks profitable. Prior to bidding, however, it is prudent for them to contact Roadtec for the name of a qualified contractor who rents Shuttle Buggies such as Hawbaker. That way, they are assured of having one available for carrying out the project.
