Because Tennessee reclaimed asphalt pavement (RAP) regulations allow paving companies like Hoover Inc. to have a larger reserve if asphalt is screened to a specified reduction size, Hoover Paving Manager Tom Hoover Jr. decided to rent a portable Atlas Copco Powercrusher PC3 to help increase the company’s RAP production.
Hoover already had its own stationary crusher, but the rented Powercrusher helped the company increase its stockpile for years of future projects, contributing 120,000 tons in its first four months of use.
When RAP production paused, the company also found use in the Powercrusher for reducing waste rock from its pit to aggregate. The crusher has the ability to “take big rocks” and ground whatever is put it in it, says Thomas Lovvorn, Hoover paving superintendent.
According to Atlas Copco, the Powercrusher’s throughput rate is 250 tph. Designed as a primary crusher, the machine kept RAP to less than 3/4 in. by running with a 5/8-in. top screen and 9/16-in. bottom screen at Hoover’s Lebanon, Tenn., site.
