Wirtgen Slipform Paver Simply Handles Shut Quarters and Tight Timing on Interstate Undertaking



The tight timeframe and shut quarters that include interstate freeway paving are powerful situations for contractors. When Capital Paving & Development took on resurfacing of Interstate 44 in Missouri, it turned to a Wirtgen slipform paver to fulfill these challenges.

The primary paving phase on the Interstate 44 undertaking had a complete width of 19 toes, the second 22 toes. Every consisted of a 12-foot-wide lane and adjoining shoulder. In whole, the undertaking stretched alongside 8 miles of freeway.

Paving was completed with the Wirtgen SP 94i slipform paver, a rugged and modular 4-track machine that matches properly on high-output tasks in difficult situations.

Truck entry to the positioning was tough, because of the lively interstate. Concrete might solely be unloaded straight in entrance of the SP 94i paver, as there was no room to feed from the aspect.

“On this undertaking, we knew we had been going to have entry points and that there could be no room for a conventional dowel basket,” mentioned Ryan Porter, Senior Undertaking Supervisor at Capital Paving & Development. To cope with that concern, the SP 94i is offered with a machine-integrated dowel bar inserter.

“As a substitute of placing the basket out in entrance of the paver and tipping excessive of it from vans, the DBI inserts the dowel bars proper behind the mould,” mentioned Tyler Kirchhoff, Foreman, Capital Paving & Development. “That makes it simpler on the crew and simpler for the tipper vans to get again.”
