Weiler Combination Compactor Meets Challenge of Asphalt Paving in Mountains
To reach compaction rates in the low 90s when placing 2,600 tons of asphalt as a driving layer three inches thick on a subdivision’s winding labyrinth of roadways on the side of a mountain range in Utah is the kind of job that requires a highly skilled crew and the proper equipment.
Staker Parson Companies had both. Staker Parson is a general contractor specializing in road and highway construction, site development, excavating and demolition, and is also a producer of sand, rock, ready-mixed concrete and asphalt. To help reach the target compaction densities on this project, the company utilized a Weiler C110 Combination Compactor.
“We’re paving on hills, up and down, which creates a challenge achieving compaction,” said Doug Howell, paving foreman. “The Weiler C110 Combination Compactor is our breakdown roller, and does most of the compaction.
“The specs require 94, and the C110 is consistently hitting 92. A finish roller compacts the last little bit. The C110 is a very versatile roller. It’s nice to have when you’re against curb and gutter, like this job. The wheels roll right on the edge and tie it into the curb really nicely.”
The C110 is powered by a 132-hp Cat C4.4 electronic diesel engine with ACERT Technology. The engine meets Tier 4 Interim emissions standards.
The single frequency and five amplitude settings provide high or low impacts for working on thick or thin lifts. The vibratory system provides high amplitude settings that apply extensive force.
The compactor features a static linear load at the front drum of 137.4 lb/in and a high centrifugal force of 31,000 pounds (138.2 kN) with a low centrifugal force of 12,400 pounds (55.2 kN).
“The C110 is a large enough roller that it can maintain a good pace, but is small enough that we can use it in driveways,” Howell said. “Having the C110 keep up with the paver helps us finish jobs a lot quicker. We’re not waiting for rollers, and trying to achieve density by having to reroll and reroll. The sooner we can hit our density targets and be done, the sooner we can move on to another job.”
The machine’s efficiency helps Howell keep expenses down. “Everything is tight. We’re really watching the hours on the equipment and the man hours,” he said.
Staker Parson Companies does a wide range of asphalt paving jobs. “We do everything from highways that are millions of dollars to driveways that are thousands of dollars,” Howell said. “We use the C110 as our finish roller when we’re paving highways.”
Operator comfort and visibility are excellent on the C110. Features include controls, levers and gauges that are easily reachable by the operator, front- and rear-facing work lights, and a rearview mirror. The hood design and rear-mounted radiator help reduce sound levels.
“The operators who run the roller really like it,” Howell said. “They like the visibility. They can see really well going forward and backward.”
Tracy Townsend, who has operated screeds, pavers and rollers in her 20 years at Staker Parson Companies, worked the Weiler C110 Combination Compactor on this subdivision job. “I like the roller, in particular,” Townsend said. “The visibility is very good. It thumps pretty hard, so I hit the densities.”
The water spray system features triple filtration, dual spray bars with 10 nozzles, dual pumps and a 160-gallon (605 L) tank. Two self-adjusting, spring-loaded scrapers and the system’s high-flow operation maximize drum coverage to prevent material buildup and keep the drum clean.
Routine component service can be easily handled at ground level and the one-piece hood tilts forward, providing easy access to the engine and cooling system, while extended oil service intervals increase uptime and reduce operating expenses.

Bergkamp Pivot Tack System for FP5 Flameless Pothole Patcher eliminates tripping hazards and keeps tack off of equipment
Tack that is sprayed into potholes to increase adhesion within a patch can also adhere to equipment hoses. In addition, the hoses can present jobsite tripping hazards. To address these common issues, Bergkamp Inc. has engineered a new Pivot Tack/Air Hose System for its FP5 Flameless All-In-One Pothole Patcher. Located at the back-right side of the FP5's hopper body, the system's pivoting arm holds the original tack hose off of the ground and parallel to the hopper, locked in place for transporting with a spring-loaded pin.

Municipalities are responsible for the care and maintenance of vast amounts of roads, from lanes to highways. When those roads are repaired or replaced, there's the potential to generate a significant amount of aggregate material - concrete and asphalt removed from the surface that must be dealt with.
Today's roadbuilding contractors are taking this material and recycling it more than ever before. However, research is showing that some municipalities are far better than others when it comes to using this type of aggregate in their roads - and some are far behind.
Municipalities across Canada are burdened with aging transportation infrastructure, much of which was constructed in the post-war era and is nearing the end of its useful life. The 2016 Canadian Infrastructure Report Card (CIRC) found that one third of municipal infrastructure across the country is in fair, poor or very poor condition, and this includes 39 percent of roads and 26 percent of bridges. Cold weather and the use of corrosive de-icing salts further threaten the reliability of the transportation infrastructure we rely on every day.
Case Construction Equipment has introduced the latest additions to the DV Series of vibratory rollers. With models available in both double drum and combination (front drum with rear pneumatic tires) configurations, these rollers are powerful, easy to transport and nimble enough to work in a variety of residential and commercial construction applications where the operator may encounter tight quarters, curbs, structures and other obstacles.
Due to the rapid increase in heavy-duty transport, the global road network is showing visible signs of aging in many places. In order to ensure that the road infrastructure remains functional over the long term, roads are increasingly requiring structural rehabilitation. Wirtgen developed the high-performance W 380 CRi cold recycler specifically to meet these requirements. This innovative machine will be unveiled to the world at the Bauma trade show.
Wacker Neuson has updated its 1.2-ton tandem vibratory roller line to include improved visibility, curb clearance and easier service access.

Additionally, they are an excellent choice for landscape and golf course contractors to statically roll sod, fairways and greens.
