<p><P>PROBLEM TO BE SOLVED: To provide an elastic pavement material using an asphalt-based binder which enhances construction performance by improving the blending of the binder so as to reduce the 180°C-viscosity of the binder while maintaining pavement strength to a certain extent. <P>SOLUTION: This elastic pavement material contains the asphalt-based binder containing asphalt, rubber, and an aggregate. The asphalt-based binder contains an ethylene-methacrylic acid copolymer. Preferably, the quantity of the ethylene-methacrylic acid copolymer blended in the asphalt-based binder is in a range of 30-80 wt.%. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
