road paving adhesives
Various types of rock materials are used in road paving which are primarily divided into two major types: acidic and basic rocks. Such minerals have different adhesive properties to bitumen. Adhesion improving additives used in bitumen solutions are designed for use in road construction as antistripping additives to improve adhesion of road bitumen to mineral materials in manufacture of asphalt concrete and bitumen-mineral mixtures.
SONDOR
Three types of adhesion-improving additives are available, i.e. type A, type B, type V. They differ in adhesive efficiency and are designed to provide bonding of road bitumen with acidic materials in manufacture of asphalt concrete and bitumen-mineral mixtures by road construction and repair companies. Adhesion-improving additives are high-temperature reaction products of amine-containing compounds with acids.
