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 Winter Grade formula is uniquely engineered to work at installed temperatures below 40º 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.
