A curable composition contains a bituminous substance (A) and a saturated hydrocarbon polymer (B) having a reactive silicon group represented by the general formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ - Si(R 1 3-a )X a €ƒ€ƒ€ƒ€ƒ€ƒ(1)
(wherein R 1 is a C 1 -C 20 alkyl group, a C 6 -C 20 aryl group, a C 7 -C 20 aralkyl group, or a triorganosiloxy group represented by (R'O) 3 Si-; when two R 1 s are present, they may be the same or different; the three R's each represent a C 1 -C 20 monovalent hydrocarbon group and may be the same or different; X is a hydroxyl group or hydrolyzable group; when two or more Xs are present, they may be the same or different; and a is 1, 2, or 3).
