E-missions covered by asphalt pavers

Wherever the paving job is, the new Caterpillar E-Series highway-class asphalt pavers are out in front on emissions requirements. The first asphalt pavers to meet Tier 4 Interim standards, courtesy the Cat C7.1 ACERT engine, the 10-foot-class AP1055E tracked paver and the sister AP1000E wheeled model are also available with the C6.6 ACERT engine for markets where only Tier 3 is required. Both engine models deliver 225 horsepower. To meet Tier 4 Interim emissions requirements, the C7.1 engine combines the Cat NOx Reduction System and Cat Clean Emissions Module. Each paver model has a dual operating station, equipped on the left side with the Advisor Monitoring System, an interactive, text-based, multi-language interface packed with fuel-saving features. These include an engine speed control that automatically adjusts engine rpm when the propel lever moves to and from neutral, and an eco-mode that lowers engine speed to 1,650 rpm when less demanding operating conditions exist. The display provides project-planning calculators, a start-up checklist, engine operating conditions and service code information. On the tracked AP1055E paver, the Mobil-Trac undercarriage uses large oscillating bogies and hydraulic accumulators to overcome surface irregularities. For more information, visit

Platform-mounted truck does not require CDL

Moving a formidable under-bridge access platform from jobsite to jobsite just got considerably easier, thanks to Terex Roadbuilding’s first truck-mounted cross model – matching the trailer platform with a truck chassis. Being within the 26,000-pound maximum gross vehicle weight limit, the HPT 11/38 does not require a driver/operator with a Commercial Driver’s License (CDL). The telescopic platform is 38 feet long and a maximum 42 inches wide and, upon arrival at the jobsite, is self-propelled into position by hydrostatic drive. Single-lane deployment takes a mere five minutes. Platform weight capacities of 1,000 pounds total and 500 pounds at the end are enough to securely accommodate multiple workers with tooling. Offering a maximum 16 feet of lowering depth and 180-degree rotation, the under-bridge access platform is ideal for applications ranging from bridge inspection and restoration to stripping operations and utility work.

VOLVO TRUCKS

Daycab tractor can run on natural gas

The United States has plenty of natural gas . . . and truck fleets have an option to put it to good use. The Volvo VNM Daycab tractor model now comes with a factory-installed natural gas option, ideal for “localized or closed-loop operations,” says Ron Huibers, Volvo Trucks’ senior vice president, sales and marketing. Such applications “present a great opportunity for companies to utilize our nation’s abundant domestic supply of natural gas,” says Huibers. “Volvo is already delivering the cleanest trucks in the world in terms of regulated emissions, and now we’re offering an alternative fuel option to move our nation’s goods while emitting less carbon dioxide.” The tractor is powered by a 9-liter, 320-horsepower Cummins Westport ISL G engine that uses clean-burning compressed or liquefied natural gas. The heavy-duty engine, generating 1,000 foot-pounds of torque, requires only a three-way catalyst to meet EPA 2010 on-road emissions standards.

VAISALA

Weather moves

Wondering what the true benefits of a Road Weather Information System (RWIS) would be for your agency? Intelligent transportation systems manufacturer Vaisala has a free, quick way for you to find out. The RoadDSS Value Calculator in an online tool that evaluates potential cost and community savings to using various RWIS or road decision support systems. The calculator asks 12 questions about road maintenance operations. Once the user has input infrastructure and cost information, the calculator uses embedded algorithms to produce calculated savings based on referenced study findings. The report provides a breakdown of all direct and indirect savings, including such safety factors as accident reductions and environmental factors such as reductions in carbon and other pollutants. A user can adjust any of the information input to tailor the end report to reflect the agency’s needs. For more information, visit www.vaisala.com/roaddsscalc
