Asphalt Additives Increase Adhesion Between Asphalt Cements and Aggregat
Asphalt Additives are any one of numerous substances that can be put into the asphalt binder to alter the characteristics of the ultimate blend of HMA. Asphalt Additives increase adhesion between asphalt cements and aggregates and improve pavement performance via reduced pavement rutting and moisture-induced damage. Effective asphalt content is the quantity of asphalt not absorbed by the aggregate; the total amount of asphalt that effectively forms a bonding film on the aggregate surfaces. Effective asphalt content is calculated by subtracting the total amount of absorbed asphalt from the total asphalt content. The asphalt binder functions being an inexpensive, waterproof, thermoplastic adhesive. In other words, it acts because the glue that holds the trail together. In its most common form, asphalt binder is merely the residue from petroleum refining. Asphalt, black or brown petroleum-like material that has a consistency varying from viscous liquid...
