Frequently asked questions:
What is the difference between Limestone and Sandstone?
Choosing the best crushed stone for driveways can be difficult if you aren’t familiar with the pros and cons of each type, so doing research is crucial.
The Layers of a Crushed Stone Driveway
Before looking at the types and sizes of crushed stone, it is important to be able to visualize what a driveway made of this material consists of:
A driveway bed of 6 to 12 inches deep, the base of which has been compacted.
Three layers of crushed stone, each about 4 inches thick.
The first and bottom layer will consist of the biggest size stone, the next will be smaller, and the last will be a combination of stone and coarse dust.
Types of Crushed Stone
Crushed stone is typically produced from limestone or sandstone. Large pieces of rock are run through a crusher, one or more times, and graded by mesh screens into different sizes.
Fine stone, fines or screenings, which are the consistency of coarse powder, are also yielded during this process. Crushed stone comes in a large variety of sizes and colors.
Our limestone has a bluish tint. When the stone is crushed, it has rough edges and surfaces that create friction when a vehicle is driven over it, making it one of the ideal materials for driveways. In addition, crushed stone driveways are natural and rustic in appearance, and come at a reasonable cost.
Limestone is a rock composed of calcium carbonate (CaC03). It is the rock type most commonly used to make crushed stone in the United States. It holds this position because it is widely available and suitable for a greater diversity of uses than any other type of rock. Limestone can be used to make cement. It is the primary ingredient of concrete. It is used as a base material for highways, rural roads, buildings, and railroad construction.
Thanks to its abundance, durability and the ease with which it can be extracted and cut, limestone has long served as an important building material. The Great Pyramid of Giza in Egypt, for example, was constructed entirely from limestone. It was also highly popular in the late 19th and 20th centuries, used on a range of buildings and monuments across Europe and the US. Limestone is also used to build roads, in the manufacturing of cement and to extract iron from its ore.

Sandstone and quartzite are composed primarily of quartz, a very durable mineral, but each has its drawbacks in the construction industry that limits its use.
Sandstone is generally composed of sand grains cemented together by calcite, clay, or silicate minerals that have precipitated between the sand grains. The cement usually does not completely fill all of the voids between the sand grains, leaving a porosity that typically ranges between 5 and 30%. This pore space allows the rock to absorb water. That water will expand in volume by up to 9% every time it freezes. Over the course of many freeze-thaw cycles, the forces of this expansion has the ability to dislodge grains and break the rock. This is why sandstone is not popular for long-term use in areas where freezing temperatures occur.
Sizes of Crushed Stone
There are many sizes of crushed stone available, usually from 1/4 inch up to 2 1/2 inch. In between, you get 3/8 inch, 5/8 inch, 3/4 inch; these sizes are all suitable for driveway construction. Fines are the smallest size, sometimes referred to as dust.
The most common sizes used in driveway construction are #2 and #3. The #2 is about 3/4 inch to 1 inch, and #3 is about 2 1/2 inches in diameter. Any of these sizes of crushed stone may come with or without fines. Stone without fines is ideal for lower levels of driveways as it lets the rainwater run freely through it and it creates a firm base.
Modified stone is a mixture of stone and fines. Stone that falls into a modified specification is sometimes used for the top layer of a crushed stone driveway as it creates a stable layer that does not easily shift about.
