Modified asphalt, preparation method thereof and asphalt concrete
The invention discloses modified asphalt, a preparation method of the modified asphalt and asphalt concrete. The modified asphalt is prepared from the following components in parts by weight: 6-22 parts of SBR (Styrene Butadiene Rubber) modified asphalt, 1.5-3.0 parts of modified apatite ore, 350-580 parts of gravel, 36-92 parts of fiber filler, 1.5-3 parts of a high-viscosity agent, 1.5-3 parts of an anti-aging agent, 80-140 parts of water, 20-35 parts of fine aggregate and 40-55 parts of coarse aggregate, and the fine aggregate comprises waste tire powder and steel slag. According to the modified asphalt, the preparation method of the modified asphalt and the asphalt concrete, a layer of black paint is sprayed on the surface of a metal souvenir before laser etching is carried out on the metal souvenir, so that the situation that a laser device is used for directly carrying out laser etching processing on the surface of the metal souvenir is avoided, and only the black paint on the corresponding part needs to be removed through laser etching; and meanwhile, the smooth and attractive degree of the surface of the metal souvenir can be prevented from being damaged.
本发明公开了一种改性沥青、该改性沥青的制备方法与沥青混凝土，按重量份包括以下各组分：SBR改性沥青6～22份、改性磷灰石矿1.5～3.0份、碎石350～580份、纤维填料36～92份、高粘剂1.5～3份、抗老化剂1.5～3份和水80～140份，细集料20～35份，粗集料40～55份，所述细集料包含废旧轮胎粉料和钢渣。该改性沥青、该改性沥青的制备方法与沥青混凝土，在金属纪念品进行镭雕之前，在金属纪念品表面喷涂一层黑色油漆，使得避免需要使用激光器直接在金属纪念品表面进行镭雕加工，只需镭雕去除对应部分的黑色油漆，便能够得到需要的图像以及文字，同时还能够避免破坏金属纪念品表面的光滑美观程度。
