Crack treatment consists of at least two and up to five steps, depending on the type of treatment( Crack Sealing or filling) , treatment policy and available equipment. These steps are:
Crack cutting
Crack cleaning and drying
Material preparation and application
Material finishing/shaping ( mainly use Crack Sealing Machine)
Blotting
Steps 1, 4 and 5 are considered optional. Crack Cutting is rarely done in filling operations, but is frequently done in Crack Sealing operations. In regions with significant annual temperature variations, typical of many northern states, crack cutting is often performed to achieve material shape factors that can provide added flexibility for withstanding high crack movements.
Most crack treatment programs use squeegees to finish or shape the material at the surface; capped and recess configurations require no finishing.
