Abstract:

PROBLEM: The coefficient of thermal expansion (CTE) is a fundamental property of construction

materials such as steel and concrete. Although the CTE of steel is a well-defined

constant, the CTE of concrete varies substantially with aggregate type, mix design,

and moisture condition.

The Mechanistic-Empirical Pavement Design Guide (MEPDG) demonstrates the

importance of CTE in design and performance of Portland cement concrete (PCC)

pavements. It is known that CTE has significant effects on slab cracking, curling and

warping, joint faulting, and pavement smoothness. A better understanding of CTE

effects on performance of Louisiana’s PCC pavements is needed.

OBJECTIVE: After summarizing the current practice for measuring CTE of PCC, the researcher will determine the variance of CTE for concrete mixes used in Louisiana and provide

recommendations for use of CTE in PCC pavement design. Additionally, the current

specification for maximum spacing of transverse joints in jointed plain concrete

pavement (JPCP) will be evaluated.
