1,000-watt light tower
 GTM Canada’s new 1,000-watt light tower illuminates
up to 100,000 square feet for nighttime road construction and maintenance.
This alternative light source is portable and easily installed by a single
person in three minutes.
The unit is light and compact — it collapses to fit
in a car trunk 2 by 2 by 1.5 feet. The light tower extends to a 15-foot
working height.

Hydroseeder
The new T280/T330 Series II HydroSeeders from Finn
Corporation are the first in the large hydroseeder line to use the field
proven clump (clutch/pump) technology. The clump’s unique single-shaft
design maximizes horsepower efficiency. The unit also features a centrally
located discharge boom; an optional remote control for engine throttle and
pump functions; a newly designed loading hatch with a larger opening and
curbside lid for more efficient loading of hydroseeding mulch; and a
low-profile pivoting hose reel with three locking positions.

Walk-behind joint cleanout saw
Sawtec’s walk-behind JS-110 Joint Cleanout Saw cuts
to a 3-inch depth and to within 1.25-inches of front walls. It cleans joints
at 20 to 60 feet per minute depending on the application and the material
being cut. Screw-down, fine depth control allows the operator to easily set
and gauge depth of cut. A new double pointer increases visibility and
improves cutting accuracy. The saw features a blade guard designed with
upcut rotation which enables easy dust extraction and allows quick
connection to a dust collection system.

Mow/apply herbicide simultaneously
 Diamond Mowers’ new Wet Blade cuts brush up to
4-inches thick and applies herbicide to the cut portion of the stem
simultaneously, saving time and money on roadside vegetation management.
Centrifugal force runs the chemical underneath the blade as it spins, where
it stays until it touches the top of stubble. A Diamond boom mower can be
fitted with the Wet Blade herbicide injection system.

Bird repellent
Bird-X’s new BirdShield is a food-grade,
biodegradable bird repellent that, after it dries, has a grape-like odor
that irritates birds, yet is environmentally friendly and harmless. Simply
paint or spray it on porous, non-porous, or sealed surfaces. Repellency is
greatest on porous surfaces and can last up to 10 days or more.

Double Joints Pavement System
 Nikolai Beloreshki, civil engineer/bridge and road
construction specialist, says the Double Joints Pavement System he developed
will help prevent the cracking and premature destruction of pavement caused
by temperature changes that cause materials to contract and expand.
The key to the DJPS technology is a rigid
trapezoidal-profile reinforcing concrete beam placed along the entire length
of the joint and not bonded to the pavement. Beloreshki says the RCB
distributes the surface loads along the entire length of the joint onto a
larger area, reducing the pressure in the base. The two sloped sides of the
RCB provide reliable support to both sides of the slab along the entire
length of the joint, allowing for free contraction and expansion of the
slab. Built-in water stops on either side of the RCB create near-perfect
waterproofing.
Advantages include:
* Improved quality and enhanced durability of
construction.
* Substantial increase in productivity and reduction
in construction time — the new technology allows for independent and
simultaneous completion of construction tasks over a larger area. Pre-cast
or cast-in-place RCB elements can be used.
* Significant reduction in investment and production
costs — the system eliminates dependency on heavy and expensive equipment.
* Elimination of vibrations and improved driving
experience.
According to Beloreshki, the DJPS technology allows
companies to become more competitive in the construction market. Companies
will no longer have to buy large concrete placing machines to bid for
highway and airport projects.

Over-height truck warning system
International Road Dynamics offers a new practical
solution to the problem of bridges and highway overpasses being struck by
over-height trucks. The Vehicle Over-Height Detection and Warning System
detects vehicles approaching areas with height restrictions, provides a
warning message to the driver, and directs the driver to take an alternate
route.
The system is comprised of a transmitter and
receiver. When the transmitter detects an over-height vehicle, a message is
transmitted to a warning device, such as flashing lights on a sign, to alert
the driver. In addition, an audible alarm can be sounded to warn the driver.

Three-wheel sweeper
The
Johnston MX450 three-wheel sweeper’s
front-and-center cab location provides an unobstructed view of the street,
curb, and gutter brooms at all times, increasing sweeping efficiency,
operator effectiveness, and safe sweeping performance. With front-wheel
