Concrete pavements represent a large portion of the transportation infrastructure. While the vast majority of concrete pavements provide excellent long‐term performance, a portion of these pavements have recently shown premature joint deterioration. Substantial interest has developed in understanding why premature joint deterioration is being observed in jointed portland cement concrete pavements (PCCP). While some have attributed this damage to insufficient air void systems, poor mixture design, or chemical reaction between the salt and the paste, it is the hypothesis of this work that a component of this damage can be attributed to fluid absorption at the joints and chemical reactions between the salt and chemistry of the matrix. This paper discusses the role of soy methyl ester‐polystyrene blends (SME‐PS) as a potential method to extend the service life of concrete pavements by limiting the ingress of salt solutions.
