Bituminous composition

A bituminous composition comprising:

• (a) a bitumen;
• (b) at least 1.0 percent by weight of at least one elastomeric block copolymer, wherein said elastomeric block copolymer is selected from the group consisting of unsaturated and hydrogenated block copolymers, said unsaturated block copolymer and said hydrogenated block copolymer prior to hydrogenation comprising
• (1) at least two polymer blocks A, said block A being predominantly a polymerized alkenyl arene block having a number average molecular weight within the range of about 10,000 to 35,000, and
• (2) at least one polymer block B, said block B being predominantly a polymerized conjugated diene block,
• (3) wherein said at least one block B is between said at least two blocks A;
• and
• (c) at least 0.25 percent by weight of a monoalkenyl arene polymer, said monoalkenyl arene polymer selected from the group consisting of a homopolymer of a monoalkenyl arene and a copolymer consisting essentially of more than one monoalkenyl arene and said monoalkenyl arene polymer having a number average molecular weight in the range of 0.4 to 1.5 times the number average molecular weight of said blocks A and said monoalkenyl-arene polymer having a number average molecular weight within the range of 10,000 to 40,000 and the amount of component (b) plus the amount of compnent (c) in the composition is within the range of about 1.25 to 15% by weight where the percent by weights are based on the total amount of components (a), (b) and (c).
