The company says the new models are easier for paving crews to handle and operate as well as improve safety. The Vögele models also have a quicker setup time.
Cat Upgrades Large Pavers – New Screeds, Paving Settings Can Be Saved
For simplified setup of similar paving projects, Caterpillar has added a new pave start assistant on its large asphalt pavers. The system, which debuted at World of Asphalt, is available on the new Cat AP600, AP655, AP1000 and AP1055 asphalt pavers. The upgraded pavers also feature Cat's new nomenclature, which drops the letter after the model number. The pavers also get new screeds: SE50 V, SE50 VT, SE60 V, SE60 V XW or SE60 VT XW. Pave start assistant records the functioning conditions of both the paver and screed, including paving width, paving speed and tow-point position, which then can be resumed by operators when needed.
A “One Person” Cold Planer: Wirtgen’s New Compact W 120 Fi
Wirtgen designed its new W 120 Fi cold milling machine to be operated by one person and packed it with much of the automated technology from its large F Series models to make it easier for inexperienced operators, the company says. It also marks the first Wirtgen cold planer with a John Deere engine since Deere acquired Wirtgen in 2017. The cold planer has a 4-foot milling width and 13-inch cutting depth, primarily for use on parking lots, driveways, pathways or as a tie-in machine on road projects. It is designed to be maneuverable in tight spaces, such as curbs and parking lot islands.
BOMAG Goes Light & Compact with Half-Lane BM 2200/65 Cold Planer
BOMAG designed its new BM 2200/65 half-lane cold planer to be light and compact for greater maneuverability and easier transport. With a 58-inch milling radius, the planer can handle such tasks as small roundabouts and cul-de-sacs. It can be used on a wide range of milling jobs, BOMAG says, thanks to various drum designs and a choice of three rotor speeds. It weighs 60,296 pounds and runs on a 630-horsepower Cummins Tier 4 Final engine.
CrackPro RMV: A Truck-Mounted Robot That Finds and Seals Road Cracks
A robotic sealcoat vehicle has hit the market that automatically finds and seals cracks and only uses two workers. The CrackPro Robotic Maintenance Vehicle is the result of a partnership between SealMaster and Pioneer Industrial Systems, whose president, Todd Hendricks, invented the concept. He said he got the idea in 2019 after watching a crack seal crew and thought there should be a safer, more efficient way. The company then set up its RMV division and reached out to SealMaster.
The Asphalt App Predicts the Price of Liquid Asphalt Up to 18 Months Out
A former executive for a large highway and heavy construction company has created an app that predicts the price of liquid asphalt for up to 18 months to help contractors bidding on projects. Brian Lawrence developed The Asphalt App, which is based on a proprietary algorithm that incorporates daily closing prices of a variety of energy products when making its predictions. Lawrence is the owner, president and CEO of Asphalt Unlimited.
Trimble’s Asphalt Compactor Technology Helps Improve Mat Quality and Paving Productivity
Trimble released its Roadworks Paving Control Platform for Asphalt Compactors, a system designed to accurately control the compaction process while reducing unnecessary passes. With it you can view compaction progress, pass counts and mat temps on a color display. You can monitor pass counts only or pass counts plus temperature, add temperature sensors or precision accuracy and wirelessly transfer intelligent compaction data from the machine to the office.
LITTLE HELPERS ON THE JOB
“The Maintainer” – Mauldin’s M415XT is a Unique Multitasking Machine
Mauldin’s M415XT is designed to give small paving contractors a lot of what they need on the jobsite without having to buy separate machines. Called “The Maintainer,” its main design is a small motor grader, but with its 10-foot boom height, and high-flow hydraulic quick-attach capability on the front and rear, it can also act as a compact loader, as well as perform a variety of other jobs, such as sweeping, compacting, loading – whatever kind of attachment you want to run, the company says.
Patch and Pave Small Areas with the Mazio Skid Paver Attachment
Contractors can turn their skid steer into a paver to patch and pave roads, pathways, bicycle tracks, parking lots, driveways and utility trenches with the new Mazio skid-steer-mounted Skid Paver. The attachment, which can be installed on any type of ISO 24410 skid steer loader, has a 1.5-cubic-yard hopper capacity, a paving width of up to 6.2 feet and a paving speed of 82 feet per minute. It can lay down hot or cold mix asphalt in thicknesses of 2 to 10 inches, while a liquid propane gas heater keeps the material heated to 284 degrees Fahrenheit.
Cut, Mill Roads with FAE’s New Aspahlt Shredders for Skid Steers, CTLs
FAE is launching three new skid steer and compact track loader attachments for shredding or cutting through asphalt and concrete roads. The RPL/SSL and RPM/SSL shredders are based on similar technology as cold planers. Teeth attached to a rotor scrape and cut to prepare a surface for a new layer of asphalt or concrete. They can also be used for excavation operations. The company is also launching an RWM/SSL model that uses a disc rotor for targeted excavations on asphalt and concrete surfaces for such tasks as laying utility lines.
Liebherr Intros its Smallest Truck-Mounted Concrete Pump, the THP 80-LP
Concrete Vibration Screed Leveling Machine For maneuvering urban and residential jobsites with limited space, Liebherr debuted its smallest truck-mounted concrete city pump at World of Concrete 2022.
