Abstract:
The main objective of this study was to evaluate factors influencing the durability of the joints in portland cement concrete pavement in the state of Indiana.

The scope of the research included the evaluation of the absorption of water in concrete, the absorption of deicing solutions in concrete, the relationship between the degree of saturation and concrete deterioration, and the role of Soy Mehyl Esters (SME) as a potential concrete sealant.

The aforementioned items were studied in conjunction with the observation of premature joint deterioration in concrete pavements. Previous work by the PI identified that deteriorating joints were observed to frequently have standing water and damaged joint sealant. This work was conducted to better understand the potential mechanisms responsible for joint deterioration, a series of mortars were tested that are consistent with the mortar fraction of concrete paving mixtures.

The first portion of the work examined the role of deicing salt solutions on the wetting and drying behavior of concrete elements. The second portion of the work examined the concept of the degree of fluid saturation and its relationship with freeze-thaw damage. The final portion of the work examined the potential use of penetrating concrete sealers (like soy methyl esters) to reduce water absorption and the corresponding freeze-thaw damage.
