• Abstract:
  The coefficient of thermal expansion (CTE) has been widely considered as a fundamental property of ; Portland cement concrete (PCC) pavement but has never played an important role in the thickness design ; procedure for PCC pavement until recently. In the Mechanistic-Empirical Pavement Design Guide ; (MEPDG), developed through NCHRP 1-37A project, the CTE became a direct input parameter that was ; closely related to pavement performance. Therefore, it was imperative to measure accurate CTE for PCC ; pavement to predict critical pavement distresses within the designed years. Research has shown that CTE is ; related to cracking, joint faulting, and International Roughness Index (IRI) in jointed plain concrete ; pavements (JPCP).
