World of Asphalt will be held in Houston, Texas, from March 6 to 8 and features educational programming and exhibits focusing on the latest technology and innovations for the asphalt industry. The Agg1 Aggregates Academy & Expo, co-located with World of Asphalt, offers educational sessions and exhibits on the latest developments for the aggregates industry. The following are highlights of products that attendees can expect to see at the shows.
The Cape May County Municipal Utilities Authority recently purchased the first BOMAG BC1172RB refuse compactor in the state of New Jersey to help increase its refuse compaction capabilities and extend the life of its landfill. The BOMAG BC1172RB is the largest refuse compactor manufactured by BOMAG. Its dimensions of 15.8 feet high by 17 feet wide and weight of 120,000 pounds give it the size and static weight to move and compact the refuse productively. The BOMAG BC1172RB has 72 teeth per wheel and weighs 120,000 pounds. Its static weight, along with the number of teeth per wheel, creates optimum compaction. It also has a two-wire cutting system for each wheel, which protects the wheels from wire wrap-arounds. Slope grading tests were conducted, showing that the machine has high ground clearance and is built to handle tough inclines.
B o t h t h e MPH362-2 and MPH364-2 models of BOMAG’s 79-inch rotor width asphalt re-cycler / soil stabilizers have been repowered with a six-cylinder, electronically-controlled 360-hp Cummins QSM11 water-cooled diesel engine, which is Tier 3 Stage III, EPA certified. Both models are available with one of three rotor configurations, including an asphalt recycler rotor designed to cut, pulverize and mix old and deteriorated asphalt pavement for reuse as road base material. Each rotor – recycling or stabilizing – is 79 inches wide and offers rotor speeds of 135 and 150 revolutions per minute. The recy-cler rotor features 168 bullet-shaped cutting teeth, which are strategically positioned for uniform material pulverizing, sizing and mixing with minimum vibration and shock load to the rotor and drive components.
Weighing in at 100,090 pounds, the BOMAG BC972RB-2 refuse compactor, an update of the BC9772RB model, is designed to deliver the size and compaction force needed to tackle the workloads of the largest capacity landfills.
BOMAG has improved key drive-train components on its 79-inch rotor width asphalt recycler/soil stabilizers. Both the MPH362-2 and MPH364-2 models have been repowered with a six-cylinder, electronically-controlled 360 hp Cummins QSM11 water-cooled diesel engine, which is Tier 3 Stage III EPA certified. Other improvements include the use of a double reduction planetary rear drive system, which is propelled by a pair of axial-piston variable displacement motors. The drive system on previous models used a ring and pinion differential assembly. The new hydrostatic system demands less horsepower than ring and pinion systems, which results in improved fuel economy. Additionally, overall cost of ownership is reduced due to fewer wear parts to maintain and repair. Upgrades to control systems and changes to electronics have also been implemented.
The Bomag BC1172RB refuse compactor includes Bomag’s exclusive premium wheel/ tooth design and performance warranty. Units are powered by a 590-horsepower, water-cooled Deutz diesel engine, with a 120,000-pound operating weight. Offering 100 percent maximum gradeability and travel speeds of more than seven miles per hour, these refuse compactors include four-wheel independent hydrostatic drive and will cover an area more than 19 feet wide with two passes.
Designed to offer contractors and road maintenance agencies the choice of a recyc-ler/stabilizer with a centre-mounted rotor, the model MPH122 features a wider rotor, greater cutting depth and a more powerful engine than previous models. All four recycler/stabilizer models from BOMAG (three are rear-mounted rotor models) feature a hydrostatic rotor drive with automatic power adjustment that allows them to stabilize or recycle a variety of materials, including oil and chip surfaces and asphalt roadways.
