Study of Preformed Open Cell Neoprene Joint Sealer for Use in Transverse Weakened Plane Sawed Joints
Various highway jointing patterns and joint sealants were evaluated. The test sections are on both a lime-treated and untreated swelling subgrade. Unsealed joints are compared to those containing preformed neoprene, standard rubberized asphalt, and rubberized epoxy. Random joint spacings were also tried. Joint movements were measured and detailed visual observations of the joints were noted. Difficulties were experienced during construction which may have led to some controversial results. It was concluded that joints sealed with the asphalt were cheaper to construct and performed better than the preformed neoprene in that they had less infiltration, spalling, and adhesion failures. It was also concluded that unsealed joints were better than those sealed. This could be a reflection of the unusually dry climatic conditions. (BPR abstract)
