How to Lay a Crushed Limestone Driveway
Apply a Weed Barrier Fabric. Cover the base with weed barrier fabric. Cover the fabric with a 4- to 5-inch layer of crushed #1 or #2 limestone rocks. This size rock resembles lemons or grapefruits and provides a firm base for the driveway. Work these rocks into position with a scraper blade attachment on the skid-steer loader or the dozer.

A Guide To The Visual Screening Of Quarries | Agg-Net
This is a technique developed to deal with visually intrusive limestone and chalk excavations. One method used in limestone quarries has been restoration blasting, where the technique seeks to form a scree and headwall-type landform found in limestone dales in central England. A similar principle can be applied to other screening landforms.
Limestone Calculator
volume needed = 3.0 m³ × (1 + 10%) = 3.3 m³. Finally, we obtain the weight of the limestone rocks we need, as shown here: weight of limestone needed = volume needed × density of limestone. weight of limestone needed = 3.3 m³ × 2,410 kg/m³ = 7,953 kg. Based on our crushed limestone calculations above, you can now call your …
