Section 6F-1-Pavement Subbase Design and Construction
This section will deal with the proper design and construction of subbases. The subbase is the layer of aggregate material that lies immediately below the pavement and usually consists of crushed aggregate or gravel or recycled materials (see Section 6C-1-Pavement Systems for more information). Although the terms “base” and “subbase

The Ultimate Buying Guide to Crushed Stone and Gravel
We often refer to all small, loose stones as “gravel.”. But actually, there is a fundamental difference between gravel and crushed stone. Gravel is a material of naturally occurring loose stone chunks with rounded edges. You can find it occurring naturally, perhaps in a gravel pit or river. Crushed stone, on the other hand, is manufactured.
· Gravel Cost. One of the cheapest options available is quarry process, which costs, on average, $0.40 per square foot. At the other end of the price spectrum is marble chips. Expect to pay $2.00 per square foot for this high-end material. River rock is a little less expensive, averaging $1.50 per square foot.
