Asphalt Paving has been Dunn's core business for over 133 years and is still the primary service we offer. From paving an interstate, a subdivision, a parking lot or patching a problem area, Dunn Roadbuilders values your business. Whether milling an existing pavement to lower the elevation for drainage before resurfacing or to remove asphalt prior to excavating an existing roadway for utility work, Dunn Roadbuilders has two milling machines to service you. Site Work may consist of grading, soil stabilization, pipe work, minor concrete and structures, utility construction or more extensive dirt work.
