Mineral powder is produced from carbonate rocks by fine grinding on special equipment.
It is used as an additive in the production of asphalts. When the product is added to the asphalt mass, its strength, wear resistance increases, and other characteristics improve. The product is added to asphalt mixtures in clearly regulated quantities. The introduction of carbonate powders into the mixture allows you to extend the service life of asphalt pavements. Coatings with the addition of a carbonate powdery substance are resistant to corrosion. Sometimes the absence of this product is compensated by the addition of bitumen, this leads to an increase in the cost of asphalt and a deterioration in its quality.

Adding to concret
Mineral powder has a positive effect on the properties of concrete, to some extent it strengthens its strength, resistance to deformation. The product helps to reduce moisture absorption. The quality of cement depends on the amount of carbonate powder. The more it is, the better the cement and vice versa.
