  Joints Pavement Interactive

  2020-6-4Types Contraction Joints. A contraction joint is a sawed formed or tooled groove in a concrete slab that creates a weakened vertical plane. It regulates the location of the cracking caused by dimensional changes in the slab. Unregulated cracks can grow and result in an unacceptably rough surface as well as water infiltration into the base subbase and subgrade which can enable other
