Here's how you can use the crushed stone calculator: Select your surface shape, e.g., Rectangular.. In surface length, enter the length of your surface, e.g., 12 feet.. In surface width, enter the width of your surface, e.g., 8 feet.. Now, enter in depth, how deep do you want to fill the layout of your surface, e.g., 3 inches.. The waste factor tells how much crushed stone …

Usually the rock is blasted or dug from the quarry walls then reduced in size using a series of screens and crushers. Some quarries are also capable of washing the finished aggregate. Figure 1. Aggregate mine. ... For instance, a newly crushed aggregate may contain more dust and thus be less receptive to binding with an asphalt binder ...
Crushed stone produces much more angular and elongated aggregates, which have a higher surface-to-volume ratio, better bond characteristics but require more cement paste to produce a workable mixture. ... The grading or size …
For example, coarse aggregate has specific grading requirements for each different size from #1 to #8. A #1 aggregate has a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate has a nominal size of 3/8 to 0.094 inch. A …
