• Abstract:
  The Coefficient of Thermal Expansion (CTE) is an important parameter in Portland Cement Concrete (PCC) pavement analysis and design as it is directly proportional to the magnitude of temperature-related pavement deformations throughout the pavement service life. Several studies in the past few years have classified the CTE as an extremely sensitive input in the Mechanistic-Empirical Pavement Design Guide (MEPDG) for structural design of rigid pavements, because the CTE affects slab stresses due to initial temperature-induced movements, corner deflections, joint faulting, pavement smoothness, and sawcut timing (ARA 2004).
