LTPP PAVEMENT MAINTENANCE MATERIALS: SHRP JOINT RESEAL EXPERIMENT, FINAL REPORT

The Strategic Highway Research Program (SHRP) H-106 maintenance experiment and the Federal Highway Administration (FHWA) Long-Term Monitoring (LTM) of Pavement Maintenance Materials Test Sites project studied the resealing of joints in concrete pavements. The purpose of joint resealing is to reduce the amount of water entering a pavement structure and to prevent the filling of joints with incompressible materials. Although joint resealing is a common maintenance practice, premature seal failure is frequent, leading to additional repair and expenditures. The purpose of this study, then, was to address the merits and deficiencies of current joint resealing materials, designs, and practices. The study evaluated the relative performance of selected sealant materials, as well as the effect of selected sealant installation methods. The study also identified sealant material properties and tests that correlate well with field performance. The effect of joint seal performance on pavement life was not addressed in this study. This report documents the entire PCC joint resealing study, including the installation of 31 unique joint seal treatments (i.e., combinations of sealant material and installation method) at 5 different test sites, the laboratory testing of experimental sealant materials, and the 7-year performance monitoring of the various joint seal treatments. It also discusses the results of comprehensive statistical analyses conducted on material performance and laboratory testing data. The results of a detailed cost-effectiveness analysis are also presented.
