• Abstract:
  The aim of this project was to evaluate the effectiveness of the crack cleaning device (CCD) for improving the current crack/joint preparation practices and for possible adoption as a standard in Nebraska Department of Roads (NDOR). Through the collaborations with NDOR and the City of Omaha, the results of surveys and field tests demonstrated the effectiveness of the CCD over the existing devices. With employing the CCD, improved road maintenance practices are anticipated. Economic analyses show its potential benefit in an economic sense; for example, a saving of about $10,000 per year is expected if replaced for a router. Taken all together, the CCD was analyzed to be the best alternative among all existing methods compared. With the positive results obtained from this project, this research recommends the adoption of CCD in crack/joint preparation work.
