Although the elasticity of the gutta percha is not as high as that of gutta percha treated by vulcanization, a part of plasticity is kept and the gutta percha becomes a rubber-plastic dual thermoplastic elastic material. High and low temperature performance of asphalt can be improved, and technical requirements of national and ministerial standards are met.
