FIELD PERFORMANCE OF A LOW-MODULUS SILICONE HIGHWAY JOINT SEALANT

A field study undertaken to evaluate the performance of Dow Corning 888 silicone highway joint sealant in various climates and pavement conditions indicates that sealant performance remains high for 6 years and beyond. Nine-year-old joints in Georgia and Michigan are performing well. Pavement seals in Connecticut, Georgia, Illinois, Indiana, Iowa, New Mexico, Michigan, Minnesota, and South Dakota, covering four major climatic zones (wet, freeze; no freeze; dry, freeze; and dry, no freeze) were inspected and evaluated. The study also identified factors that affect performance. Of these, installation procedures and shape of the actual seal are the most influential and also the most controllable. The inspections revealed that Dow Corning 888 silicone highway joint sealant can overcome inadequacies in field installation procedures and provide a reasonable seal life.
