Anti-stripping agents in surface dressings

2 Usage of anti-stripping agents 3.7.2./ Anti-stripping agents in surface dressings 

As it was mentioned, the anti-stripping agents are used in surface dressings. They may be incorporated using one of the following ways  

The first way is fairly time-consuming and thus is rarely used. The second one significantly reduces the viscosity of the bitumen film and delays the bond development. The third way has an advantage over the other ways, since a good adhesion is achieved not only between aggregates but also with the old surface. Thus, the third way has been established and is used because of more positive results observed.
