Biological method for improving adhesion of asphalt and granite aggregate
The invention discloses a biological method for improving the adhesion of asphalt and granite aggregate, which is characterized in that calcium carbonate is generated by mineralizing and depositing bacillus pasteurii on the surface of granite, so that the granite is subjected to surface modification, and the adhesion of the asphalt and the granite aggregate is further improved. The surface modification specifically comprises the following steps: soaking granite in a bacterium solution containing bacillus pasteurii, and then adding a mineralizing solution for blending culture, so as to realize modification treatment on the granite surface. The method is simple in process, the adhesion of the granite can be improved by 2-3 grades, and the method is a biological green and environment-friendly method.
本发明公开了一种提高沥青与花岗岩集料粘附性的生物方法，其是利用巴氏芽孢杆菌在花岗岩表面矿化沉积产生碳酸钙，从而对花岗岩进行表面改性，进而提高沥青与花岗岩集料的粘附性。所述表面改性具体是利用含巴氏芽孢杆菌的菌液浸泡花岗岩，之后加入矿化溶液进行共混培养，以实现对花岗岩表面的改性处理。本发明方法工艺简单，可使花岗岩的粘附性提高2~3个等级，是一种生物绿色环保的方法。
