Hot Mix, Warm Mix & Cold Patch Asphalt
Hot Mix Asphalt is a high quality, thoroughly controlled, engineered material comprised of approximately 5% asphalt and 95% aggregates (rock, gravel and sand), using asphalt cement as a binder. The asphalt is a petroleum product and the aggregates are mined and then crushed in local quarries. All of these materials are required to meet certain standards established by PennDOT and other agencies to assure that they will perform their intended functions.
All HRI, Inc. asphalt plants meet or exceed all required quality and safety standards set by local, state and federal governments, and have over 200 asphalt mix designs available.
Warm-mix asphalt technologies allows HRI, INC. to lower the temperatures at which material is mixed and placed on the road. Reductions of 50 to 100 degrees Fahrenheit have been documented. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases. In addition, engineering benefits include better compaction on the road, the ability to haul paving mix for longer distances, and extending the paving season by being able to pave at lower temperatures.
A blacktop patch material consisting of sand, ¼" aggregate and emulsified asphalt. The cold patch is stockpiled at our plant locations and is ready to use with no mixing or heating required. HRI manufactures cold patch according to the Penn DOT Bulletin 27 specifications. Cold patch is typically used for temporary patching during the off season, when hot mix asphalt is not available.
