A moisture curable composition which is useful for sealing pavement joints consists essentially of 100 parts by weight of a hydroxyl endblocked polydiorganosiloxane, 55 to 120 parts of non-reinforcing, non-acidic filler wherein at least 40 percent by weight of the filler is treated with calcium stearate, 2.5 to 10 parts of diacetamidosilane, and 1 to 6 parts of aminoxysilicone compound. The composition is self leveling when applied to a horizontal surface and when cured has an elongation of at least 1200 percent, a durometer on the Shore OO scale of from 45 to 75 inclusive, and a modulus at 150 percent elongation of less than 50 pounds per square inch.
