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。

Emulsion tests and recovered-binder tests are separate. Use the recovery method and conditions shown; confirm the required specification edition and application-specific tests with your enquiry.
Grade selection also depends on the aggregate and intended treatment. Packaging, handling conditions, storage
period and final specifications are confirmed for each enquiry.
