摘要
用附聚法和降粘法浓缩ＳＢＲ１５０２胶浆制取道路沥青改性用胶乳。结果表明：总固物质量分数可由（２１±２）％上升到４５％～５０％。该胶乳与齐鲁石化公司炼油厂１００号乙沥青混合，改性后的道路沥青具有良好的使用性能，可满足高等级路面沥青的技术要求。
The latex for road asphalt modification was prepared using SBR 1502 rubber cement by the coneentration of agglomeration and viscosity reducing methods.The result showed that the total solids content increased from(21±2)%to 45%～50%.The modified road asphat had good scrvice properties.
