借助乳化剂将细小沥青液滴分散于水中。电荷、破乳行为及集料相容性影响选型；乳液与回收结合料的测试须分开核对。 同一项目中的粘层、表面处理和冷拌料也可能需要不同的乳化等级。请提供施工用途、集料资料、规定的破乳类别、所需试验和储存安排。
这些是SRNT目录的参考限值，不是批次实测结果或COA。每次询价须确认可供性、标准版本及合同限值。
技术指标名称和目录脚注保留英文，以确保含义准确。

K-grade names and acceptance limits depend on the destination-market specification. The test procedure, sieve opening, recovery method and storage-test period must be agreed before acceptance. “Agreed method” identifies a procedure to be set in the purchase specification.
Grade selection also depends on the aggregate and intended treatment. Packaging, handling conditions, storage
period and final specifications are confirmed for each enquiry.
