Clear view of drums and edges
 Bomag’s redesigned
BW161AD-4 features slanted drum-support legs that give the operator a clear
view of the drum edges, eliminating the need for operators to lean out of
the cockpit during operation. Bomag says the design also gives the operator
an unrestricted view of the drum surface and sprinkler system across the
entire 66-inch rolling width.
The 21,826-pound tandem is powered by a
131-horsepower diesel. It uses a new exciter system to deliver 36,000 pounds
of centrifugal force at 2,700 vpm and 27,225 pounds at 3,600 vpm — increases
of 23 and 60%, respectively, compared to the previous model. Other features
include a sliding, pivoting operator seating system, and a number of
maintenance access features, including wide-opening engine access doors that
eliminate the need to raise the operator platform to perform engine service.

5 new crack-sealing features
 Cimline has
introduced five new features for its Magma series crack sealing machines in
2004. The Superflex III heated hose is said to have the lightest weight and
smallest diameter of any electrically heated hose in the field. Using a
third-generation Teflon core, the hose is extremely flexible and can be
handled without gloves.
The wand is new, too, featuring a lightweight,
adjustable handle and a recirculation feature that is said to prevent
spillage. A trigger on the handle controls flow, while a ball valve is used
to control drips. Cimline has also added a 30-gallon-per-minute material
pump, up from 20 gpm in the previous model.
Two other features are new options: an integrated
air compressor for crack cleaning and sealing in one operation, and a dual
hose option.

Produces heat, not emissions
 Astec says its new
Phoenix Talon aggregate-drying burner achieves high efficiency and ultra-low
nitrous oxide and carbon monoxide emissions because of a unique design that
combines pre-mix, gas-burning technology and advanced air-atomized,
nozzle-mix oil burning technology. The result: it can operate in areas with
the tightest standards for NOx with no modification. The operator simply
changes the excess air level via the controls in the control house to
operate in the lean-burn range.
The design incorporates an integral fan, as well
as silencers, which make the Talon one of the quietest burners on the
market, according to Astec.

New spec for PQI method
TransTech Systems
reports that AASHTO has released a new specification covering the use of
electromagnetic surface-contact devices for measuring the density of hot-mix
asphalt pavements in situ. AASHTO TP68 explains the use of such devices
which determine density by measuring the changes in the electromagnetic
field that result from the compaction process. The TP68 test method is a
rapid, non-destructive technique that can be applied by relative correlation
or by comparison with core samples that offer a know density of the actual
material under test. TP68 details the apparatus to be used, preparation of
the test site, correlation of the device by relative or core comparisons,
operation of the device, and the recording of results.
TransTech’s PQI 301 Pavement Quality Indicator and
prior versions are covered by the new specification.

upsized its motor grader offerings with the addition of the 130-horsepower,
25,300-pound model 785. The new model’s frame has 40 degrees of
articulation, and a 17-foot, 4-inch wheelbase. Its turbocharged powertrain
includes a six-speed powershift transmission. Its rear wheels are gear
driven, and it has internal multi-disc brakes. The 12-foot moldboard has 60
inches right or left side shift and an open, 54-inch, gear-driven turntable
with 360 degrees of rotation and a 23-inch lateral shift. LeeBoy recommends
the 785 for ditching, grading, and site preparation, as well as maintaining
gravel roads and removing snow.

Two new commercial pavers debut
 Ingersoll-Rand
has introduced two new commercial pavers that combine established big-paver
technology from
Blaw-Knox and small-paver innovations from IR. The 73-horsepower,
15,500-pound 3020 comes standard with IR’s V-3 Xtend-a-Screed. It paves 8-
to 13-feet wide, using screed-under-screed technology, and its extensions
have been redesigned for more torsional stiffness and precision placement.
The 3020 has an 8-ton hopper and dual independent auger and conveyors
systems. It has the lowest hopper bed in its class — 21.5 inches — to
minimize truck bed and hitch interference during the transfer of asphalt to
the paver. Curved hopper wings improve material flow and enhance clean up.
One size above the 3020 is the new 3120 paver. The
15,800-pound unit features an 87-horsepower engine and IR’s Liberty Screed
which paves in 8- to 15-foot widths. The Liberty screed has front-mounted
hydraulic extensions, a four-burner propane heating system, and the ability
to adjust both the angle of attack and the height of the extensions. It has
the same low-profile hopper bed as the 3020.

Beefed-up commercial paver
LeeBoy says its
new 8515 asphalt paver retains the maneuverability and size of its popular
8500 series paver, but adds big-paver enhancements that reduce operating
costs and increase productivity for users. New from the ground up, the 8815
has a heavier track assembly and undercarriage, and a hydraulically raised
hopper bed that provides maintenance access to the undercarriage and tracks.
The 74-horsepower tractor has a two-speed
hydrostatic drive and carries a 7.5-ton hopper that features heavy-duty
radius hopper wings that enhance the flow of material into its dual 36-inch,
slat-feeding conveyors. The screed is a beefed up Legend system with
long-wearing sonic augers and heavier cutoff plates for clean starts and
stops.

Wheeled excavator reaches anywhere
Gradall says the
new XL 4300-II is the first 45,000-pound excavator to combine a tilting,
telescoping boom and wheeled mobility for on- or off-road surfaces. Gradall
claims the 166-horsepower machine’s load-sensing hydraulics maximize its
productivity in excavating and demolition applications, while its
traditional tilting/telescoping boom lets the unit excel in fine grading,
sloping, ditching, truck loading, spreading rip rap, trimming trees, and
other delicate functions. The boom design also creates a low working
profile, enabling the machine to work under bridges, beneath tree limbs, and
in tunnels where conventional excavators may not be able to operate. The new
model has a maximum digging depth of 20 feet, 11 inches, maximum ground
level reach of 30 feet, and a bucket breakout force of 25,449 pounds.

Mid-size reclaimer brings versatility
 Wirtgen has
introduced a mid-sized, 400-horsepower stabilizer/ reclaimer as a
high-performance, versatile alternative to its production-size,
670-horsepower WR 2500 S. The new WR 2000 cuts grades or asphalt roadways up
to 20-inches deep and has a maximum cutting width of 79 inches. It
stabilizes with both emulsion and foamed asphalt, and can be equipped with a
high-capacity water pump for dry soil conditions, or cement- or lime-
stabilization work. The cutter features a V-belt drive and automatic
tensioner, and four speeds, from 112 to 181 rpm. Wirtgen says the new drive
system delivers more power to the cutter with less maintenance than previous
chain and hydraulic system designs.

Versatile, high-production planer
Roadtec’s new
RX-900 cold planer can be ordered with either an 860- or 950-horsepower
engine and can operate as a three- or four-track machine. The machine has a
maximum cutting depth of 14 inches, and can cut in widths of 7 feet, 2
inches; 8 feet, 2 inches; 10 feet; or 12 feet, 6 inches. Roadtec says the
three-track mode makes the unit more maneuverable in deep cuts, while the
four-track mode is best for straight, 2- to 3-inch cuts.
