• Abstract:
  This report contains a product evaluation of Thoro System's "Roadpatch" and "Thorite". Roadpatch is a cement base, fast-setting patching material. The material is fortified with special alkali resistant glass fibers. It is designed to repair potholes in portland cement concrete. Roadpatch was demonstrated in Arizona on a section of concrete pavement. In a two-year evaluation, the product performed well. All of the patches held up under heavy traffic. The Arizona Transportation Research Center recommends that this material be considered for use on maintenance projects. Thorite is another Thoro System product. It is fast-setting, non-shrink material for patching curbs. The Thorite material cracked and failed within one year. The patch did not bond well to the original concrete or to the other patches. Based on its poor performance, the Arizona Transportation Research Center has recommended not using it on further curb patching projects. /Abstract from report summary page/
