LTPP Data Analysis: Relative Performance of Jointed Plain Concrete Pavement with Sealed and Unsealed Joints
NCHRP 20-50(2) was conducted to compare, based on the data available from the LTPP studies, the performance of JPCP designed and constructed with unsealed joints to that of JPCP with sealed joints. There are just five LTPP sites suitable for this analysis: the SPS-4 sites in Arizona, Colorado, and Utah. These sites are all located in the dry western region of the United States, for which reason it would be unwise to extrapolate the results of this analysis to other regions of the country that receive more precipitation. Nonetheless it is hoped that the analysis methods used in this study may serve as useful examples for future analyses of other sealed-versus-unsealed joint experiments in other climates. Despite the conventional wisdom concerning the need to keep concrete pavement joints well sealed, previous studies on the subject have not demonstrated that JPCP with sealed joints and JPCP with unsealed joints perform differently in terms of spalling, faulting, IRI, or deflections.
