Specifications include, but are not limited to: All open cracks and joints from 1/4” to 1-1/4” shall be routed to remove at least 1/8” from each sidewall. This will result in a minimum reservoir width of 1/2” to a maximum reservoir width of 1-1/2”. The depth of the routing shall be approximately a one to one ratio (width to depth), subject to the discretion of Public Works. Cracks wider than 1-1/2” shall be repaired using pothole repair techniques instead of sealing or as directed by Public Works. Routing shall be performed on all new cracks and joints, and cracks and joints with loose, sunken, or missing sealant. No sealant shall be installed until all cracks and joints have be cleaned free of all deleterious materials, including any dust, old sealant, incompressibles, and organic material*, and are sufficiently dry. Following the initial routing and cleaning operation, all cracks and joints shall be HCA lanced within 10 minutes of application of the sealant. Equipment for the two operations should be kept in a compact configuration such that not more than 50 feet separates equipment required by the two operations. Extreme care shall be used to ensure the crack sidewalls do not become overheated and burned. *When vegetation exists in the cracks and joints, it shall be removed and those cracks and joints shall be treated with a herbicide that sterilizes the soil subject to the approval of the City.
