Paver Setup

• Verify paver tractor and screed are properly maintained, greased, fueled, and fully operational.
• Verify all equipment is ready including electronics, skis, and cables.
• Perform safety walk around check, check fluids, and condition of screed plate, augers, chains, extensions, attachments.
• Use stringline, paint, or fixed structure to establish steering guide.
• When using joint matcher, position sensor at leading edge of screed.
• Verify mat width to avoid longitudinal joint in wheel paths.
• Block screed up and use stringline to check for crown or verify flatness of screed and extensions.
• Use starting blocks or asphalt pad under screed to establish thickness of roll-down. (~1/4 inch per inch of compacted thickness)
• Use CAT Paving-By-The-Numbers as generic guideline for paver setup. See your specific manufacturer’s manual for specifics.
