一般抗剥落剂是在沥青与集料混合的前几个小时加入，但考虑到天气等意外情况，处理好的沥青有时需要在超过170℃的条件下存放几个星期。竞争对手的抗剥落剂由脂肪胺制成，受热很快分解。三、四个小时后其抗剥落性能大幅度减少。雅美公司生产的AD-here® LOF 65-00是氨基胺的衍生物，即使高温放置几个星期，其抗剥落性能也不会减少。相对于脂肪胺，AD-here® LOF 65-00有更长的胺链和更大的分子量，这就大大降低了产品受热时的挥发度。

The general anti stripping agent is added in the first few hours before mixing asphalt with aggregate, but considering the weather and other unexpected situations, the treated asphalt sometimes needs to store for more than 170 weeks. The competitor's anti - stripping agent is made from aliphatic amine, and the heat is quickly decomposed. After three or four hours, its resistance to exfoliation decreased greatly. The company's AD-here LOF 65-00 is an amine derivative, even if the high temperature placed a few weeks, the anti stripping performance is not reduced. Compared with fatty amines, AD-here LOF 65-00 has a longer amine chain and a larger molecular weight, which greatly reduces the volatilization of the product when it is heated.

为说明抗剥落剂的稳定性，做了一系列的AASHTO T-283测试。PG 64-22沥青中加0.5%的 AD-here® LOF 65-00，置于170℃的烘箱中，在0、7、14和21天后分别将该沥青样品与集料混合、压实（集料是花岗岩和石灰石的混合物）。然后进行静态断裂测试。

In order to illustrate the stability of the anti - stripping agent, a series of AASHTO T-283 tests were made. PG 64-22 bitumen plus 0.5% AD-here LOF LOF 65-00 is placed in 170 degrees oven. After 0, 7, 14 and 21 days, the bituminous sample is mixed and compacted with aggregate, which is a mixture of granite and limestone. Then the static fracture test was carried out.
