| description | The invention discloses a preparation method of modified granite aggregate, and an adhesion testing method. The preparation method comprises the following process steps: heating styrene-butadiene-styrene triblock copolymer (SBS) modified asphalt, then adding a liquid anti-stripping agent into the heated SBS modified asphalt, stirring evenly, and placing the obtained mixture in an environment of 175-180 DEG C to prepare a mixed solution a; weighing granite aggregate and cement, and heating up to 175-181 DEG C; then, uniformly stirring the heated granite aggregate and cement, and carrying out heat preservation at 175-180 DEG C to obtain a mixture b; blending the mixed solution a in a mixing container, adding the mixture b during blending, and uniformly stirring to obtain the modified graniteaggregate. The modified granite aggregate is placed in a constant temperature water bath at 76-84 DEG C, part of the aggregate is taken out and put into cold water at set intervals, and the aggregateis completely taken away |
