Asphalt cold planer SB-3000

David Madden explained the crews must pave back what they’ve milled up by the end of the shift in Texas and Louisiana where Madden Contracting Company LLC, headquartered in Sibley, Louisiana, performs a substantial amount of mill-and-inlay work. To get pavement prepped and all the tons down consistently, Madden himself has gotten creative and his crews have trialed a number of new machines over the years, including the SP-200 spray paver from Roadtec Inc., Chattanooga. With the launch of the new SB-3000 from Roadtec, Madden Contracting has continued its experimental spirit with positive results. In 2019, Madden Contracting performed a 4-inch mill and inlay with a Superpave C mix, sealcoat and permeable friction course (PFC) on a section of U.S. 79 in Texas. The team was so pleased with the outcome, they submitted the project for a Texas Asphalt Paving Association (TXAPA) quality pavement award, which is now under review. This spring, the crew repeated the project on the next section of U.S. 79, using the SB-3000 in front of the paver. “It’s an absolute mirror image,” Greg Greathouse said. He’s the roadway superintendent for Madden Contracting/Longview Asphalt Inc. and worked on both sections. “They tie into each other. Each job is about 5 miles long.”
