Joint Sealants for Airport Pavements. Phase I. Laboratory Field Investigations
The objectives of this study were to determine the essential characteristics of sealants for joints in Portland cement concrete (PCC) airport pavements that should be incorporated in specifications and select best candidate sealants for field evaluation. Laboratory and field investigations of sealants were performed for data needed to meet these objectives. Major factors that sealants must be resistant to are: chemicals (jet fuel, hydraulic fluid, lubricating oil), physical (elongation, compression, intrusion), and environmental (thermal, sunlight, weathering). In laboratory specification conformance tests, only 3 of 18 (17%) of the sealants passed the tests. In field inspection of sealants and discussion with airport personnel, there was no one clearly outstanding performing seal that was identified; however, several airports favored the Dow Corning 888 silicone seal. There is a strong indication of material of specification (or both) deficiencies. Sealants selected for evaluation in Phase II have the following material compositions: silicone, polyurethane, coal tar/polyvinyl chloride, and chloroprene. Keywords: Coatings; Sealers; Concrete joints; Runways. (KT)
