Addressing drying shrinkage in concrete, Aug 30, 2019· However, even with good joint design, some drying shrinkage cracking can occur between the joints, resulting in maintenance issues and repair costs Reducing drying shrinkage, and thus the need for joints in a concrete slab, can reduce the overall maintenance cost and improve structural performance Reducing shrinkageConcrete Engineering, MnDOT Smoothness Program What we do The Concrete Unit provides leadership and assistance to agencies, contractors, and consultants on specifying, constructing and maintaining long lasting concrete structures and pavementsConcrete Pavement Joint Design and Construction, Concrete Pavement Joint Design and Construction Louisiana Transportation Conference February 10, 2009 Dr Michael Ayers Director of Education and Training Why Joint Concrete Pavements?
