Derry Construction Paves the Way with Cat SDX Screed Plates

The Cat SDX Screed Plate System is transforming paving operations, and Derry Construction is leading the way as the first in western Pennsylvania to implement it. Designed for superior performance, these innovative screed plates enhance density, create smoother surfaces and reduce change times, making them a valuable upgrade over traditional screed plates.

Enhanced Compaction and Density

One of the standout benefits Derry Construction has experienced with the SDX Screed Plates is improved and more consistent compaction across the width of the mat—the new asphalt surface behind the paving machine.

“The most impressive part about the plates is how even they compact the asphalt through the entire width of the road,” said Paul Pavsek, superintendent for Derry Construction. Asphalt compaction typically decreases as you move away from the center of the road. However, the Cat SDX plates ensure greater compaction with even distribution across the entire width of the roadway.

This even compaction contributes to better International Roughness Index (IRI) scores and overall road durability. By minimizing air voids and increasing density, the SDX plates help contractors achieve a more uniform surface, leading to better long-term performance of paved roads.

Potential for Greater Efficiency

Along with improved compaction, Derry Construction has noticed the potential for increased efficiency in their existing paving process since implementing the SDX plates.

“We usually use two rollers to follow the paver and get it more compact,” said Daniel Slavek, vice president of Derry Construction. “We think we may be able just to use one roller with these plates.

Reducing the number of rollers needed on a job could save time and operating costs. With less reliance on additional compaction equipment, paving crews can complete jobs faster while maintaining quality.

How the SDX Screed Plates Work

Unlike traditional flat screed plates, the SDX design features a three-dimensional angular surface at the front and a tapering smooth surface at the back. As asphalt passes through the grooves, this creates a kneading action, reducing air voids and increasing the density behind the screed. The plates also strengthen unconfined edges and improve joint matching, leading to higher-quality pavement.

Key benefits of the SDX Screed Plate System include:

• Better Quality: The kinetic mixing action of the plates increases density and smoothness while improving joint matching capabilities.
• Faster Service: Hardware-free installation allows screed plates to be changed quickly, reducing downtime.
• Increased Longevity: The design runs flatter than traditional plates, leading to longer wear life and interchangeable modular plates for even wear distribution.

Real-World Results

Derry Construction’s early success with the SDX Screed Plate System highlights its advantages for paving contractors. Improved density, more uniform compaction and potential reductions in roller use all contribute to a more efficient and cost-effective paving process.

When Derry Construction first wanted to use these plates for paving in 2024, Caterpillar sent one of the system’s engineers to assist. Along with Cleveland Brothers, Caterpillar provided guidance and ensured a smooth transition as they used the system for the first time.

The Cat SDX Screed Plate System offers a compelling solution for contractors looking to enhance road quality while reducing downtime and maintenance. Derry Construction’s experience demonstrates that the system delivers real-world benefits, making it worthwhile for paving projects of all sizes.
