Stone
P.J. Keating Company's quarrying operations in Lunenburg, Dracut, and Acushnet, Massachusetts, as well as Cranston, Rhode Island, supply our Hot Mix Asphalt and other business operations with the raw materials they need. We also supply crushed stone to a number of outside buyers and contractors.
We quarry, crush and screen millions of tons of stone every season. P.J. Keating Company recognizes the aesthetic value of nature and the frailty of the environment. Retired lands are restored in a positive program of reclamation.
Aggregate Calculator
The Aggregate Calculator helps you to estimate the aggregate tonnage required for your job. To use the Aggregate Calculator, simply enter the width, length, and thickness of your job, and click on whether you are measuring the thickness in feet or inches. Next, click on either Base Rock, Drain Rock, or a custom density selection. The Base Rock and Drain Rock selections will fill in the density of the rock for you; the Custom selection allows you to enter a rock density in the Density field. Finally, click on the "Calculate" button. The calculator will estimate the number of tons of aggregate that will be required. Click here to calculate.
* Please note that densities will vary somewhat between different loads, but the default values assigned for Base Rock and Drain Rock are good standard "rules of thumb" for estimating.
