Crushed stone is a construction aggregate with a very similar appearance to gravel. However, gravel is naturally rounded and eroded over time, whereas crushed stone is mined and then crushed into specific sizes for practical applications. Grades of crushed stone are categorized by the size of the new stones after the mined material has been crushed.
Crushed stone is a sustainable resource that can be made from many varieties of hard rock. The most common types of rock used are quartzite, granite and limestone. York Building Products uses Pennsylvania’s natural abundance of limestone to produce AASHTO #8 and other grades of crushed stone. At our Principio Quarry in Port Deposit, MD we produce our AASHTO #8 from the local source of granite.
Professionals use different types of crushed stone in various construction projects, from pavement base material to utility pipe bedding and even decorative lining for walkways.

AASHTO #8 is an angular crushed stone used across a wide range of structural and surface applications. To help you understand this stone better, we have answered a few of the most common questions, including what makes it effective for concrete and asphalt production, why it will not compact and why that works in your favor.
Yes, AASHTO #8 is suitable for concrete mixes because its consistent grading creates a uniform, workable product, asphalt mixes because its consistently sized particles blend smoothly with asphalt binder for a stable surface, pipe bedding because it allows water to drain freely around utility lines and driveway topdressing because it gives you a clean, uniform surface layer that holds up well under regular use.
#8 stone “will not compact” because it doesn’t have fines to fill the gaps between particles, and that is important for your application because the open structure allows water to drain freely, making it suitable for pipe bedding, drainage layers and other projects where water movement is a priority.
#8 is highly effective as a raw material for concrete and asphalt production as its consistently sized particles create uniform mixes, giving concrete slabs their structural durability and blending smoothly with binder in asphalt for a stable, long-lasting surface.
The exact size range of AASHTO #8 crushed stone is half an inch down to about three eighths of an inch in diameter, making it a practical choice for concrete and asphalt work, pipe bedding and any application that needs a workable material.
Yes, #8 can be used for both structural applications and decorative driveway topdressing because it performs well in concrete and asphalt mixes and as bedding for pipes and tanks and has a clean appearance. You will need a compacted base layer underneath if you want the surface to stay firm.
