Are you heating your PMA optimally without damaging the binder?
This guide by industry veterans Ron Corun and Bob Kluttz outlines the essential best practices for handling polymer‑modified asphalt (PMA) at the plant.
We talk critical steps—emptying tank heels, using dedicated storage tanks, proper circulation in horizontal tanks, and avoiding direct-fire heat to protect binder integrity. We also spotlight temperature control, slow re‑heating after long storage, shear‑thinning viscosity behavior during production, and practical setup for pumps and slat conveyors. We also underscore the importance of clean truck beds, careful compaction temperatures, and the shortened working window for highly modified (HiMod) binders.
