Type of emulsion

(OP)
In our project, for construction of crushed stone base layer the constituent aggregates are silicate but the constituent aggregates of first asphalt layer are carvonate. What type of emulsion we must apply, anionic or cationic?

RE: Type of emulsion

For silica aggregates, it makes little or no difference. For carbonate aggregates, I would use an anionic emulsion since the pH of the aggregate is going to be alkaline. Anionic emulsions are also alkaline.
