Modified aggregate as well as preparation method and application thereof
The invention relates to a modified aggregate as well as a preparation method and an application thereof. The method comprises the following steps: spraying an ethoxysilane coupling agent aqueous solution on the surface of the aggregate; and curing the aggregate sprayed with the ethoxysilane coupling agent at the temperature of 150-180 DEG C to obtain the modified aggregate. The invention also comprises the modified aggregate prepared by the preparation method. In addition, the invention also provides an application of the modified aggregate in preparation of an asphalt mixture. The modified aggregate can be firmly and stably adhered to asphalt and has good water stability.
本发明涉及一种改性集料及其制备方法和应用。该方法包括以下步骤：将乙氧基硅烷偶联剂水溶液喷洒于集料表面；将喷洒有乙氧基硅烷偶联剂的所述集料于150‑180℃下固化得到所述改性集料。本发明还包括上述制备方法制备得到的改性集料。另外，本发明还提出一种上述改性集料在制备沥青混合料中的应用。该改性集料能够与沥青牢固稳定的黏附，且具有较好的水稳定性。
