Beschreibung
Zusammenfassung:	The present invention provides a reactive modified asphalt and a method for producing same; in particular, a reaction-bonded modified asphalt that can be subjected, with concrete, to chemical cross-linking and a physical fitting effect is provided; the reactive modified asphalt is prepared using starting materials comprising asphalt, a rubber modifier, and a waterproof bridging agent; one end of the waterproof bridging agent is combined with the C=C double bond, carboxyl (-COOH), and carboxyl (-OH) in the asphalt, and the other end is combined with the hydroxyl or acid radical generated after cement hydration; a chemical cross-linking reaction is performed with concrete; the modified material is tightly joined with cement into an integral body; the relevant parts have the function of a chemical bond, and after curing, have an irreversible bonding effect; during the process of solidification of the cement, the waterproof material creeps into and penetrates the pores of the cement gel and concrete, achieving a tight bonding effect that is tight, firm, and irreversible.
