Best Practices for Crack Treatments for Asphalt Pavements

Crack sealing and crack filling are widely used treatments for maintenance of asphalt pavements. However, successful crack sealing and crack filling applications continue to be viewed as an art. When not properly applied, these pavement preservation treatments can result in early failures and costly corrective maintenance for highway agencies. Although much research has been performed in the United States and abroad on the materials, techniques, and designs for crack sealing and crack filling, variability in the current state of the practice regarding construction techniques and the resulting effectiveness of crack sealing and crack filling have not been investigated. This report presents best practices for crack treatments for asphalt pavements developed through a critical review of the current states of the art and practice. The research included a critical review of the worldwide literature on crack sealing and filling, with emphasis on identifying current best practices. A survey of state, local, and provincial highway agencies was then conducted to fill gaps in the results of the literature review. This report fully documents the research and includes chapters on the current states of the art and practice that support the chapter discussing the selected best practices. It will be of interest to engineers in public agencies and industry with responsibility for construction and maintenance of asphalt pavements.
