Cobleskill Rehabs Two Stretches of I-88
Established in 1954 with the purchase of a limestone quarry in Cobleskill, New York, Cobleskill Stone Products Inc. has grown into an aggregate producer, material supplier and construction services provider for upstate New York. When it comes to asphalt paving jobs, a large portion of the company’s business revolves around overlays for states, counties and municipalities. Recently, the firm used a Dynapac MF2500CS mobile feeder to help pave two rehabilitated stretches of I-88—one near Schenevus, and the other near Central Bridge.
“Continuous paving also eliminated bumps in the mat from the machine stopping and letting the screed settle, which resulted in a more consistent and higher quality finished product.”—Sam Galasso
Multiple Lifts, Smooth Results
“The Central Bridge project included three lifts of blacktop to put down,” explained Michael Moore, vice president of Cobleskill Stone Products. Those were a base, binder and top course.
“The job specs only required using a material transfer vehicle (MTV) for the binder and top course, but we chose to use one for all three courses,” added Dan Mark, the project superintendent on the Central Bridge project.
Mark explained that using an MTV allowed the crew to eliminate truck transitions, lay more tons at a consistent speed, and provide “better rideability.”
Job specifications for the MTV included a 30-tonnage capacity between the MTV and the hopper.
“We looked at multiple brands before choosing the Dynapac MF2500,” Moore said. “Using a tracked machine opposed to a wheeled machine had specific appeal because we were working with crack and seat material. Once we established the carrying capacity met the job specs, we looked at the remix capabilities built into the machine and the oscillating conveyor, and it was clear the machine fit the bill for how we wanted to approach the project.”
The Dynapac MF2500CS mobile feeder has a maximum operating speed of 82 feet per minute and a feed capacity of 2,000 tons per hour, when using an optional swing conveyor, or a feed capacity of 4,000 tons per hour with a standard conveyor.
At the I-88 Schenevus project, Cobleskill Stone Products’ operators typically laid 17 feet of asphalt per minute, totaling upwards of 3,000 tons of material per day, which allowed them to complete echelon paving with two pavers running side-by-side for a portion of the project.
“One of the days, we were able to lay almost 3,400 tons of material,” noted Sam Galasso, supervisor. “The MF2500 helped tremendously with production and eliminated the cold joint in the center of the mat. Continuous paving also eliminated bumps in the mat from the machine stopping and letting the screed settle, which resulted in a more consistent and higher quality finished product.”
“Machine uptime for the I-88 project was 100%,” Moore said. “The user-friendly interface made it easy to operate and allowed our operator to train other employees to run the machine.”
When looking for the right machine for the I-88 project, Cobleskill Stone Products turned to Steve Kenney, a sales representative at Anderson Equipment Company, and Tom Kiselica, the paver and feeder marketing developer at Dynapac.
“The machine was fit for this job site,” Kenney said. “The controls are directly in front of the operator, who can operate the machine from either side of the cab.”
Cobleskill Stone Products also relies on Anderson Equipment Company and Dynapac for support.
“Both Tom and Steve have been excellent,” Moore said. “They checked in on the job’s progress and machine’s performance multiple times. We’ve worked with them before and know that they go above and beyond to make sure our Dynapac equipment is running.”
