Tech Brief - July 2024 - Proper Joint Preparation
To seal or not to seal has been a question for more than a quarter century. Joint sealing has been a process in constructing concrete pavements for over a hundred years, yet the challenge of quality installation continues. The purpose of joint sealing is to reduce the amount of water entering a pavement structure and to prevent the filling of joints with incompressible materials.
