The state of interface on rubber particle and asphalt mixture was observed by a scanning electron microscope. As a result, it was found that the surface of untreated rubber particles is not bonded with the asphalt, but polymer treated mixture was found to have the affinity of rubber particles with asphalt improved. Tensile bonding strength was tested on rubber plates and asphalt. The result revealed that the polymer-reformed mixture has two times as large tensile bonding strength as that of the untreated mixture. With regard to the characters of asphalt mixture mixed with rubber particles, the stability shows a decreasing trend as compared with the standard asphalt concrete, but presents an excellent performance in wear. The fluidity resistance value is inferior to the standard, but not as great as presenting a problem under normal using environment, where its applicability as a road paving material was verified. 4 figs., 2 tabs.
