Abstract: “Usually the adhesiveness is defined as the capacity of a binder to cover an aggregate without dispersing itself when touching the water or the traffic aggressions. Therefore, the adhesiveness additives are products that improve the adhesiveness of the bitumen to a certain aggregate. The improvement of causeway’s bitumen adhesiveness is becoming a current practice in our country, especially when is used acid (siliceous) aggregate. The used additives – amino derivatives - have a high stocking stability, a low toxicity degree toward the amine, diamine, polyamine-based additives and are liquid products perfectly compatible with all bitumens and easy to use, in comparison to the paste or solid additives, which must be made liquid to be used. The mineralogyc nature of aggregate is, also, very important because the bitumen „prefers” basic aggregates. However, in practice, the most used aggregates for hot (or cold) coating are acid. There is a continuous problem for specialists to find the opt”
