3/4-inch crushed rock. 3/4-inch crushed rock is a common size of crushed rock that is commonly used for a variety of construction and landscaping rock projects. The main purpose of using 3/4-inch crushed rock is to create a stable and durable base layer that can support heavy weight, withstand heavy traffic, and provide proper drainage.
improves the size distribution and range. Crushed stone is also a processed aggregate. It is created when the fragments of bedrock and large stones are crushed so that all particle faces ar e fractur ed. Variation in size of particles is achieved by screening. Aggregates that have received little or no screening are known as crusher run.
AASHTO #8 is a large grade of crushed stone. Like AASHTO #1, #3, and #57, it is a clean material that will not compact. However, the top size of AASHTO #8 aggregate is significantly smaller, making it ideal for different applications within the construction industry.

Coarse aggregates are those that have a nominal size of more than 4.75 mm, such as gravel, crushed stone, and blast furnace slag. Fine aggregates are those that have a nominal size of less than 4.75 mm, such as sand, silt, and clay. Filler materials are those that have a nominal size of less than 0.075 mm, such as cement, fly ash, and lime.

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller.This product is often referred to as 1/4'" minus as it refers to the size, or grading, of this particular aggregate.
The crushers sort the rocks by size, separating them into piles labeled with a size number. Some common crushed stone sizes you will encounter are: #1 – The largest crushed stone, around 2 to 4 inches in size. #2 – From 2 to 3 inches in size. ... #10 – The smallest classification of 1/4 inch or less. Often referred to as stone dust.
It means that the stone was put through the #57 sieve which produces gravel stones of about 1" to 1.5" in size. #1 crushed stone refers to the largest sized crushed stone. It is about 2″ to 4″ in size. Its uses are for tor larger jobs such as culvert ballast. At the other end of the size chart is a very small-sized stone — #411 stone.
This is the largest size of crushed stone, usually measuring between 3 and 8 inches in diameter. Its primary use is for erosion control, like stabilizing shorelines and slopes. Understanding Screen Sizes and Crushed Stone …
Explanation: Crushed stone, gravel and ordinary sand are examples of normal weight aggregate. They are commonly used in manufacture of normal weight concrete, asphalt concrete and roadway sub-base. 7.
Here's a look at the size of crushed stone grade that varies from small to large. Small Crushed Stone (Less than ¼ Inch to ¼ Inch) Small crushed stone is often used as both a decorative and functional surface layer—on top of a compacted base and sub-base layer—for many construction and landscaping projects, such as:
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 …
