Claims13
A curable composition which comprises (a) 10-90% by weight of an epoxy-modified diene-based block copolymer containing a polymer block consisting of an aromatic vinyl compound and a polymer block consisting of a compound having a conjugated double bond, in which unsaturated double bonds are partially epoxidized, (b) 90-10% by weight of asphalt mixed with tar, and (c) a curing agent for an epoxy-based resin.
A curable composition wherein 1-100 parts by weight of tar is mixed with 100parts by weight of a curable composition comprising (a) 10-90% by weight of an epoxy-modified diene block copolymer consisting of an aromatic vinyl compound and a polymer block consisting of a compound having a conjugated double bond, in which unsaturated double bonds are epoxidized, (b) 90-10% by weight of asphalt, and (c) a curing agent for an epoxy-based resin.
A cured article molded from a curable composition as set forth in any one of claims 1-6.
An asphalt emulsion which comprises;
- (i) 100 parts by weight of asphalt, (ii) 5-100 parts by weight of an epoxy-modified diene-based block copolymer containing a polymer block consisting of an aromatic vinyl compound and a polymer block consisting of a compound having a conjugated double bond, in which unsaturated double bonds are partially epoxidized, (iii) 30-800 parts by weight of water, and (iv) 0.06-8 parts by weight of an emulsifier.
An asphalt mixture for paving which comprises 1-5 parts by weight of fillers, 1-15 parts by weight of a water-hardenable inorganic material, 2-15 parts by weight of a modified asphalt emulsion containing an epoxy-modified diene-based block copolymer, and 100 parts by weight of aggregates.
