Shelly and Sands, Inc. purchased its first ever and the first ever sold in Ohio Wirtgen slip form barrier wall machine after a successful demonstration to replace an aging machine. The Wirtgen slip form barrier wall 4 track machine model SP25 was put to work first on I-70 in St. Clairsville, Ohio.

The SP25 easily slipformed a 60” high barrier wall on Beaver Excavating’s ODOT project. The mix was supplied by Tri-son Concrete and was dry batched and dispatched through transit mixers and introduced into the auger feed system that was provided at the time of the demonstration. It was later swapped out for a bi fold conveyor feed system that unloaded dry batch mixed concrete quicker into the mold. The folding conveyor gives easier placement of the machine when hauling from job to job. Foreman on the job Chris Stillion commented on how smooth the propel system was compared to other machines he uses. The operator of the machine likes the visibility from the operators control station and its smoothness when pouring dry mixes such as barrier wall mix designs.

Shelly and Sands, Inc. put another Vogele Niveltronics Big Ski system on one of their newest Vision series paver, Kelly Paving division’s KF407 to help in smoothness and ride ability specifications for the IRI testing in Eastern Ohio on the Douglas Applegate Connector in Steubenville, Ohio. This will be the 14th or more Big Ski they will utilize for their screed automation in grade and slope applications. The Niveltronics Big Ski has been successful for Shelly and Sands, Inc. in achieving multiple smooth paving awards throughout Ohio and retaining incentive bonus money many times. The crews at Shelly and Sands give the Niveltronics system very high marks for ease of use and accuracy. “It’s plug and play”…

Also used on this project in conjunction with the latest in paving technology from Vogele America’s paving division Shelly and Sands, Inc. is using the latest in compaction technology from the Hamm roller division. The new Hamm roller model HD 110+VVHF vibratory roller is capable of over 4000 v.p.m in low amplitude used in combination as displayed with the new Hamm model HD120+OV oscillatory roller. The HD120+OV allows for more time available for compaction (T.A.C.) as it is nondestructive in nature and allows the operator more time further back on the asphalt mat to get the required density without destroying the integrity of the material in the asphalt mix.
