If the owner uses normal care, homogeneous materials can be safely stored without worry of polymer separation1. But, if a compatibilized PMAC is cooled, then reheated, manufacturers recommend the owner circulate the tank to distribute the temperature evenly, even though agitation is not necessary. Not all deliveries of PMAC will be used immediately. The polymer-modified asphalt supplier can give more specific information on the product being used. If reheating is required, owners should do it gently, taking care not to overheat the modified asphalt.
Some owners prefer hot oil heating systems to prevent localized overheating.
Recirculating the material in the tank helps distribute the heat, just as it does with any asphalt material. Polymer-modified asphalts don't necessarily require new equipment purchases Preblended, compatibilized, modified asphalts do not require special equipment during production. Millions of tons of such polymer materials have been successfully used in batch or drum mix plants without any special equipment, alterations or additions to the plant2. Experience shows that the production of hot mix with compatibilized, modified asphalt that is ready to use is not much different from normal mixes. There are some subtle differences, however, which owners should take into consideration to get the most benefit from the enhanced properties.
