MODIFIED ASPHALT COMPOSITION AND PAVEMENT OF BRIDGE USING THE SAME

摘要

The present invention relates to a modified asphalt composition for bridge surface pavement, which comprises: 70-96 wt% of straight aspha 1-10 wt% of residue; 1-10 wt% of a thermoplastic resin; 1-10 wt% of petroleum based PITCH; and 0.01-0.5 wt% of a thermal stabilizer. The present invention can increase the elasticity while reducing the thickness so as to be excellent in bending followability to the steel plate.
