Sunflower Paving Inc., a full-service paving company with locations in Lawrence, Topeka and Kansas City, was originally founded as a flatwork company 30 years ago. Gradually, Sunflower Paving expanded its concrete division into other facets of commercial concrete, including everything related to horizontal concrete, such as public and private work on curbs, sidewalks, paving and handicap ramps.
In 2009, the company purchased Asphalt Improvement Corp. to form its asphalt division, specializing in county highways, municipal street overlays, parking lots and asphalt patching.
The expansion into asphalt spurred Sunflower Paving to form a new milling division just a year later to help crews keep up with an increased workload.
“We started the milling division because while we were doing asphalt work, we were waiting on milling subcontractors to arrive and get the work done on time,” says Jeff Engroff, president of the Lawrence-based company. “We decided to bring the milling in house to do milling operations on our own jobs and for other contractors.”
Finding the right machine
A milling machine is obviously a significant investment, so Engroff and Travis Burris, director of the asphalt and milling divisions at Sunflower Paving, made sure to do their homework.
“Before we buy a new piece of equipment, we determine what the guys in the field want — not only what they’re used to, but what they want to use,” Engroff explains. “We research the brand in terms of its quality and the service the dealer will provide. Then we try to make the best judgment possible to acquire the highest quality machine and the best service we can get for the price.”
After careful consideration of all equipment alternatives, Sunflower Paving decided to purchase the Volvo MT2000 milling machine.
“The Volvo MT2000 was a new machine and the company went out of its way assure us they would stand behind the machine,” Engroff adds. Sunflower Paving’s experience, results and success with the new machine affirm the company’s decision.
“Adding the capability of a new milling machine not only allowed us to satisfy our jobsite needs, but it also allowed us to be more flexible in our work scheduling,” Burris adds. “It was ‘hit or miss’ when we were waiting for subcontractors. Now, having our own milling machine allows us to take care of the work more quickly, easily and more efficiently.”
Sunflower Paving purchased the machine from The G.W. Van Keppel Company, Kansas’ full-line Volvo dealer headquartered in Kansas City. “We work with both the Topeka and Kansas City branches of G.W. Van Keppel. They provide us with the training that we need to operate the equipment efficiently. They are quick to help us with our service and support needs,” Engroff says.
New services provided
Sunflower Paving’s milling crew, which consists of Foreman Lee Torneden and two to five crew members depending on the application, use the new milling machine on asphalt projects, including full-depth patching on streets, city street milling and overlay projects, and county and state highway milling and overlays. They also perform concrete milling on road and bridge projects.”
Powered by a Cummins QSX-15 6-cylinder engine, the unit with a 78.75-inch drum handles milling depths up to 14 inches and has three distinct cutting speeds to allow the operator to match productivity and fuel consumption and meet sound level restrictions for each individual project.
Advanced technology aboard the milling machine provides clear communication regarding the milling operation along with operator convenience, including multiple diagnostic screens with easy-to-read messages displayed for quicker diagnostics and troubleshooting.
The load control technology keeps track speed from exceeding the parameters for conveyor capacity and engine speed for improved productivity. Its stability control system has a dedicated sensor that monitors the cross slope of the machine and automatically adjusts the support legs back into balance if the machine begins to operate outside the acceptable balanced range.
