Newsbrief - Information about crack and joint sealants now on the Web

Crack and joint sealants are used in the construction, maintenance and rehabilitation of pavements made of asphaltic or cementitious concrete. Sealing is one of the most common approaches used to limit the intrusion of water, salt and grit into joints and cracks, resulting in reduced deterioration and extended service life for pavements.

The performance of these sealants depends on the characteristics of the pavement and the method of installation, as well as on the type of sealant used, making it difficult to determine what the best product for a particular job really is. At present, there are dozens of publications on sealants and fillers for cracks and joints, but much of this literature is published by transportation agencies and departments in the form of internal reports; as a result, needed information is not always accessible to other interested parties.

To help improve access to information on this subject, IRC has developed two Web sites that make articles, reports and references more widely available.

  • This site provides a Canadian and urban perspective, highlighting the work of IRC's Urban Infrastructure Rehabilitation Program in increasing the durability of crack sealants and improving their installation. Documents can be downloaded or ordered from the Web site.
  • Site of the U.S. Transportation Research Board's committee on sealants and fillers for joints and cracks, provides a North American perspective on the subject through its reviews of current specifications, and material and equipment suppliers. The site also provides useful links and references.
