A self-leveling silicone composition, which isuseful as a sealant in contact with asphalt, cures uponexposure to moisture in the atmosphere to an elastomer havingan elongation of at least 1200 percent and a modulus at both50 and 100 percent elongation of less than 25 pounds persquare inch. The composition consists essentially of ahydroxyl endblocked polydiorganosiloxane, non-acidic,non-reinforcing treated filler, diacetamido functionalsilane, aminoxysilicone crosslinking compound andnon-reactive silicone fluid diluent.
