Abstract:Freezing and thawing damage is the most common cause of distress in Kansas pavements. Many
locally available aggregates in Kansas do not meet current standards for use in concrete pavements because
of poor freeze-thaw durability. The use of nanotechnology to potentially improve the performance of
aggregates with poor freeze-thaw durability in concrete was explored. Aggregates were impregnated by
silica, alumina, and titanium nanoparticles, sealed with three different sealers, or soaked in a latex solution
before inclusion in concrete mixtures and testing in freezing and thawing. Additionally, a powdered latex
additive was added as a cement additive to an additional concrete mixture. While the nanoparticles, two
sealers, and soaking in the latex solution slightly improved the performance of concrete in a freezing and
thawing environment, none of the treatment methods improved the performance significantly enough for
inclusion in Kansas pavements.
