NATIONAL SURVEY OF ACP CRACKSEALING PRACTICES

This report was initiated to review current cracksealing practices employed by transportation departments across Canada. A telephone and follow-up written survey solicited responses to questions regarding departmental policy, practices, materials and research. The results of the survey indicate that in areas where cracksealing is employed as an annual maintenance activity, the methods and materials utilized are quite similar to each other. The current state-of-the-art method includes: routing of cracks, cleaning with compressed air, sealing with a high quality hot-pour asphalt sealer and squeegeeing. Some jurisdictions use a hot lance to pre-heat and dry cracks before sealing. Most jurisdictions support the philosophy that cracksealing is beneficial to extending the life of pavement. Most research is aimed at testing new, longer lasting mateirals and installation techniques which would improve the economics of cracksealing. (A)
