Quality of asphalt pavement depends a lot on bitumen adhesion to the aggregate. Good adhesion depends on bitumen properties we use and aggregate we mix. In our market the most common aggregates are: dolomite, granite, gravel, kvarcit/diorit and bitumen comes from different refineries. Very often adhesion is weak and has to be improved by adding liquid or solid additives into the bitumen tanks or bitumen supply to the pug mill line. Liquid additives may be of different chemistry and convenient for automatic dosing by using special dosing equipment or manual adding if product is solid and packed in 25 kg bags.
We have very wide range of additives to improve bitumen’s adhesion, but before we offer the best, we recommend to make laboratory trials with real aggregate, bitumen and selected additive.
