End use drives residue level, break rate, and additive selection. Tack coat grades need controlled breaking and good adhesion on dusty or aged surfaces. Slurry or micro surfacing needs specific viscosity and compatibility with fillers and aggregates. Waterproofing grades need film formation, flexibility, and often polymer modification. Plant configuration follows, including storage segregation, additive dosing systems, polymer tanks, higher torque mills, and temperature control. If you plan to supply both road and waterproofing products, dedicated tanks and cleaning protocols become essential to prevent cross contamination.
