Slipform machines have given us the ability to place long sections of high quality pavement.
Slipform machines have given us the ability to place long sections of high quality pavement.

The advent of slipform paving gave contractors the ability to produce high-quality concrete roads using moving forms technology. Electronic controls and microprocessors have greatly improved the way slipform pavers operate, with great advances in control systems, which today feature self-diagnostics and intelligent electronic-over-hydraulic control. The increasing demand for better quality roadways continues to drive the research and development for machines to produce a smooth and durable pavement.

No one could have imagined 50 years ago the amount of truck traffic on today's road system. Maintaining and rebuilding today's roads has driven the industry to be more creative. Today, we can slipform a four-lane, 50-foot wide road in a single pass. I think the workers of the past would be very impressed with the quality we achieve today.
