Kentucky Transportation Center
The Kentucky Transportation Center has developed CatStrong CRP-X, carbon fiber reinforced polymer rod panels that are bonded to existing reinforced and deficient pre-stressed concrete bridge structural members to increase their capacity. Production uses small-diameter carbon fiber rods set on a fiberglass mesh to form a sheet ranging from CRP-70 to CRP-195. A CatStrong CRP-80 panel can resist more than 80,000 pounds of tensile force per 1-foot-wide section and weighs only 2.9 ounces per square foot, according to its maker. That square foot provides a strength equivalent to a square foot of A36 steel that is 0.12 inches thick and weighs 4.85 pounds. Visit www.betterroads.com/info.
Nonstop, seamless slurry transfer
The VSS Macropaver Slurry Transfer Vehicle (STV) can be run continuously without creating seams, and works with any brand of truck-mounted slurry machine. It can load aggregate at 8 tons-per-minute and both water and emulsion at 200 gallons-per-minute, and the STV allows the paver to work uninterrupted while applying slurry or microsurfacing. Emulsion and water are fed into the STV via a hose from the conveyor-equipped nurse unit tank using separate hydraulically driven 3-inch self-priming centrifugal pumps. The STV also can be used as a loader on stockpile sites or on jobsites, eliminating the need for a front end loader, emulsion and water storage tankers.

Operator friendly artic
John Deere’s 460E articulated truck is the largest of Deere’s E Series ADTs. The 46-ton 460E features a Deere PowerTech 13.5L IT4 engine with 481 net horsepower. A purpose-built ZF transmission includes a high-capacity retarder, eight forward and four reverse gears. New axles include on-the-fly differential locks and outboard planetaries, and each axle is independently pressure lubed and filtered. The axles use internal wet disc brakes with independent cooling circuits. When ground conditions get soft and difficult, the system canl automatically control the axle differential locks as well as the inter-axle differential lock, all while the truck is still moving. A newly designed stay-tight oscillation joint, high-suspension travel on all axles, and balanced weight distribution provide agility. An onboard weighing system allows operators to view the weight and the number of loads carried.

Pothole repair in four steps
Jetpatcher Road Repair Machines range from 2.5 to 10 cubic yards of hopper capacity, with emulsion tanks to suit. They use a four-stage process for asphalt repairs. Stage 1 uses a high-volume, low-pressure blower to clear loose debris from the pothole. In Stage 2, the Jetpatcher coats the pothole with an asphalt emulsion that seals the hole and prevents further moisture damage. Stage 3 mixes aggregate with the asphalt emulsion, which is then blown into the hole. In Stage 4 a light layer of dry aggregate is applied to the patch, preventing it from sticking to tires before the emulsion is fully cured. The patch is now ready for traffic.
