Old asphalt pavement regeneration additive, method for preparing regenerated asphalt pavement mixture from old asphalt pavement regeneration additive and preparation method thereof
The invention discloses an old asphalt pavement regeneration additive, a method for preparing a regenerated asphalt pavement mixture from the old asphalt pavement regeneration additive, and a preparation method thereof. The addictive comprises the following components in percentage by weight: 80-90% of tung oil; 9-15% of mineral oil; 1-5% of rosin resin; 4%-15% of an ethylene-vinyl acetate copolymer; 4%-15% of powdered butadiene styrene rubber; 1%-5% of hydroxide; the preparation method of the old asphalt pavement regeneration additive comprises the following steps: S1, weighing the componentsin percentage by weight; S2, heating the mineral oil to 100-120 DEG C while stirring; S3, adding rosin resin, and continuously stirring for 30-60 minutes at the temperature of 100-120 DEG C, so thatthe rosin resin is completely dissolved; and S4, sequentially adding the ethylene-vinyl acetate copolymer, the powdered styrene-butadiene rubber and the hydroxide. The old asphalt pavement regeneration additive, the method for preparing the regenerated asphalt pavement mixture from the old asphalt pavement regeneration additive and the preparation method thereof can improve the durability of an asphalt pavement and are easy to popularize.
本发明公开了一种旧沥青路面再生添加剂及其制备再生沥青路面混合料的方法及其制备方法，由下列重量百分比的组分组成：桐油：80～90％；矿物油：9～15％；松香树脂：1～5％；乙烯‑醋酸乙烯共聚物4％～15％；粉末状丁苯橡胶4％～15％；氢氧化物1％～5％；旧沥青路面再生添加剂的制备方法，包括以下步骤：S1、按重量百分比称取各组分；S2、将矿物油搅拌下加热升温至100～120℃；S3、投入松香树脂，在100～120℃下继续搅拌30～60min，使松香树脂全部溶解；S4、依次投入乙烯‑醋酸乙烯共聚物、粉末状丁苯橡胶和氢氧化物。该旧沥青路面再生添加剂及其制备再生沥青路面混合料的方法及其制备方法，能够提高沥青路面的耐久性，易于推广。
