June 2, 2016

CSHub researchers are working to understand pavement fracture at all levels, from the nano-scale up, so it is important to have a model that allows for the evaluation of cracks as they are forming in the concrete. This brief explains the development of a new two-phase representation, which incorporates the elastic material properties of the pavement and subgrade, and offers a more realistic response which allows researchers to more accurately model eigenstresses (stresses produced without external loading).
