GOMACO’s Paver-Mounted GSI a Paving Contractor’s Tool GOMACO is experiencing an increased demand for the new paver-mounted GSI (GOMACO Smoothness Indicator) as a tool for paving contractors checking their rideability on-the-go. GOMACO introduced new hardware and software for this paving contractor’s tool at World of Concrete 2012 in Las Vegas. The pavermounted GSI was displayed on a GOMACO GP-2400 two-track slipform paver. The new paver-mounted GSI will feature new durable hardware with a wider, 7 in. (17.8 cm) diagonal touch-screen monitor and a new adjustable mount for achieving the optimum viewing angle. A single CAN-based connection is all that is now needed to the screen, reducing cable runs and connections while adding versatility to the adjustable screen mount. WiFi, Bluetooth and USB connectivity also will be added to the new model to provide wireless printing and wireless downloading and uploading capabilities from a laptop. Behind the scene software enhancements will include easier setup and troubleshooting guides, as well as new userfriendly screens for data visualization. The paver-mounted GSI provides immediate smoothness readings, right out of the paver, and displays these readings on
the touch-screen monitor so they can be viewed instantly. The GSI traces the slab and takes smoothness readings simultaneously from three different sensors on each trace. The GSI can trace up to eight wheel tracks, for a total of four lanes in a single pass. The GSI trace over the new slab will provide smoothness readings in multiple indexes, including the GSI number, IRI, PI (profile index based on the California profilograph), or it can be exported as an .erd file to create several other indexes. The indexes are derived from the true profile of the surface, determined by the data collected. These indexes are viewed and monitored on the GSI’s touch-screen monitor. The on-the-go surface smoothness information includes station and footage documentation for later reference of bump and smoothness locations. The GSI’s bump alarm can be set with project parameters. If a bump occurs during paving that is out of parameter, a bump warning is displayed and the bump’s station location is marked on the graph for exact reference. The GSI’s feedback allows on-the-go adjustments to fine-tune the paving operation. Contractors instantly know how changes to a number of different paving
variables directly affect the quality of the ride. Instant results eliminates having to wait until the cured concrete has been profilographed to see how the variables affected ride. The GSI also is available as a mobile unit, providing the same smoothness monitoring and quality assurance as a pavermounted GSI. It also can be outfitted with GSITools, GOMACO’s software application that performs post processing of exported GSI trace data. With GSITools, the GSI can be used in a variety of applications, including the Grade Analysis Tool, which can build a profile of the grade and estimate the concrete yield of the project. The GSI Survey Tool is a new application. A GSI trace over an existing roadway can provide data for a 3D model in an overlay application. The GSI will collect the data with multiple traces (up to eight) in a single pass. This single pass with the GSI on the project totally eliminates the tedious handwork of two survey engineers and provides an accurate visualization of an existing roadway for a 3D model to be used for stringless paving of an overlay project.

Two paver-mounted GSI units monitor the smoothness of the new concrete slab. The information is instantly displayed and reviewed on a single touch-screen monitor mounted on the side of this GOMACO GHP2800 paver.
Terex Streamlines Its Roadbuilding Organization Terex has streamlined its North American Roadbuilding manufacturing facilities, enabling it to work more closely as a unit and offer improved equipment sales and service to its customers. Leading this effort, Don Anderson, general manager of Terex Roadbuilding, now has managerial responsibilities for all three North American road building equipment facilities located in Canton, S.D., Fort Wayne, Ind., and Oklahoma City, Okla. “Terex continues to be the only manufacturer to offer contractors a full array of both asphalt and concrete Terex has streamlined its North American Roadbuilding manufacturing facilities, equipment solutions,” said closely as a unit and offer improved equipment sales and service to its customers. Anderson. “We are focusing on our core road and bridge building businesses and right-sizing those businesses to meet Roadbuilding district managers in North America will have sales responsibilities for the entire road building equipment demand, so we can better serve our customers.” Continuing its commitment of servicing and supporting offering, which includes more than 75 products from the customers and dealers, Terex Roadbuilding North America three North American manufacturing facilities. Leading this team is David Rinas, who now serves as has realigned its field sales force to mirror the centralized focus at the factories. Beginning in 2012, all Terex director of sales and marketing of Terex Roadbuilding North
America. Rinas joined Terex in 2009 as sales director of Terex front- and rear-discharge mixer trucks in Fort Wayne and now also serves as interim site director of the Fort Wayne facility. He now has sales and support management responsibilities throughout the United States and Canada for the entire Terex Roadbuilding asphalt and concrete equipment lines. “We maintain a diverse and experienced field sales force, with some of our district managers tallying more than 30 years of experience in providing equipment soluenabling it to work more tions to dealers and contractors,” said Rinas. “By allowing them to sell the entire product offering — no matter if it’s an automatic roller paver from our new manufacturing facility in Canton, an asphalt paver or reclaimer/stabilizer built in Oklahoma City or a mixer truck from Fort Wayne — this enables our district managers to develop a deeper relationship with our dealers and customers.” For more information, visit www.terex.com.
