Intended use dictates the residue level, viscosity, and break profile. Tack coats require controlled breaking and strong adhesion on thin films. Slurry and cold mixes require stable handling and controlled mixing with aggregates and fillers. Waterproofing needs film formation and flexibility, often requiring polymers. Plant configuration follows these needs by adding dosing systems for modifiers, specialized storage, filtration, and instrumentation. If multiple end uses are produced, the plant needs dedicated tanks and strict cleaning to avoid contamination that changes break behavior or compromises membrane or road performance.
