摘要
PROBLEM TO BE SOLVED: To provide a modified asphalt composition, an asphalt mixture and an asphalt pavement material, which are excellent in work efficiency during production or pavement execution, excellent in rut resistance, crack resistance, water resistance or the like as asphalt pavement, and further excellent in long-term storage stability and uniformity.;SOLUTION: This modified asphalt composition contains 100 pts. wt asphalt (A), and 1-20 pts. wt modified polyethylene (B) formed by grafting an unsaturated silane compound to polyethylene as much as 0.1-5 wt%, wherein, in the modified polyethylene (B), a melt flow rate measured by 21.16N load at 190°C based on JIS-K7210 (1999) is 2-100 g/10 min., and a melting peak temperature by a differential scanning calorimeter is 100-140°C.;COPYRIGHT: (C)2012,JPO&INPIT
