PERFORMANCE OF ARIZONA'S SPS-4 JOINT SEALING ENVIRONMENT
This paper describes how Arizona is one of four states that has built and monitored experimental concrete pavement test sections with sealed and unsealed joints as supplements to the LTPP SPS-4 experiment. The supplemental experiments in three of these states differ from the other SPS-4 sites in that the pavements were constructed for the experiment, and incorporate a variety of joint sealant types and joint configurations, as well as narrow unsealed joints. The performance of concrete pavement test sections and the joint sealants at the Arizona SPS-4 site has been monitored since the pavement's construction in 1991. This monitoring has included deflection testing, distress surveying, profile measurement, test section length measurement, joint width measurement, and joint sealant condition evaluation. The paper presents the findings from nine years of monitoring of the performance of the pavements and joint sealants at the Arizona SPS-4 site.
