Zusammenfassung:	A latex composition includes (i) 100 parts by mass (in terms of a solid content) of an anionic latex containing, as a main component, a conjugate diene copolymer containing (A) 55 to 99.99% by mass of a conjugate diene unit, (B) 0.01 to 5% by mass of an unsaturated carboxylic acid unit, (C) 0 to 44.99% by mass of an aromatic vinyl compound unit, and (D) 0 to 40% by mass of another unsaturated compound unit copolymerizable therewith, (ii) 0.1 to 20 parts by mass of a nonionic surfactant, and (iii) 0.1 to 10 parts by mass of a cationic surfactant. The latex composition has both of an excellent compatibility with an asphalt and a strong adhesiveness to an aggregate.
