UPM cold asphalt mixes are seasonally adjusted to work in all weather, all year-round. Just choose the proper grade for your temperature and use it as needed. The Spring/Fall Grade formulation is engineered to perform at installed temperatures from 40º – 60º F. Unlike HMA, UPM cold mix can be stockpiled and used on an as-needed basis. It requires no heating and it can be loaded into trucks and taken right to the location of the needed repair. UPM cold mix requires only a shovel and the truck tires to compact it. So no additional machinery or equipment is necessary. UPM® Permanent Pavement Repair Material cold mix has none of these restrictions or limitations. 50lb bag - 56 Bags per Pallet.
