Hollow-glass-micro-bead heat-resistant asphalt mastic-gravel mixed material and preparation method therefor

The invention discloses a hollow-glass-micro-bead heat-resistant asphalt mastic-gravel mixed material and a preparation method therefor. The mixed material is prepared from SBS modified asphalt, hollow glass micro-beads, coarse aggregates, fine aggregates, mineral powder and a fiber stabilizer which serve as raw materials. According to the mixed material, the compressive strength is high, the number of surface pores of the mixed material is relatively small, the oil absorbency is relatively low, the cooling effect is good, and the preparation method is simple. 本发明公开了种中空玻璃微珠热阻沥青玛蹄脂碎石混合料及其制备方法，由SBS改性沥青、中空玻璃微珠、粗集料、细集料、矿粉及纤维稳定剂为原材料制备而成，该混合料的抗压强度高，混合料表面孔较少，吸油率较低，降温效果好，并且制备方法简单。
