Heritage Group businesses came together today for a Cold Central Plant Recycling project in Boone County. US Aggregates, Asphalt Materials, Heritage Research Group, Milestone Contractors and Pavement Maintenance systems were involved in supporting the Boone County Highway Department with an asphalt recycling project. We sectioned off an area in the NW corner of our Thorntown Plant for Boone County to use for this project. The production of Engineered Emulsion Cold Central Plant mix took place in this designated area of the quarry. The material was used to pave County Road 700 N to the west of the plant. ONE HERITAGE!
