Research Brief: An Analysis of Concrete Joint Sawing

September 16, 2015

As concrete hardens, internal stresses can result in the formation of random, uncontrolled cracks in portland cement concrete (PCC) pavements. Joints are cut to release some of these early-age stresses and to avoid uncontrolled cracking. This brief describes research the Hub is conducting to ultimately find the answer to an important question: What is the latest time (also known as the level of maturity) before which pavement joints must be cut to avoid the generation of random cracks?
