2A modified crushed stone is a type of well-graded aggregate typically used in road construction. These small stones have few air voids between them and are modified with additional elements, such as stone dust, making them the perfect solution when a dense, uniform base is needed. Also, 2A modified stone has a specific size and grading that meets Pennsylvania Department of Transportation (PennDOT) specifications.
As a fine-sized aggregate, 2A modified stone is made up of a combination of crushed particles that come in various sizes. This stone option often has a 2 1/2″ top size and ranges down to dust.
Since 2A modified stone is ground down to smaller particles, it has the unique characteristic of being compact. As a result, this material is often used in construction projects where compaction is needed. 2A modified makes the perfect base material in road construction and provides a stable foundation for asphalt and concrete application. The compactable aggregate can improve the overall durability and stability of the surface by creating a solid base that can withstand traffic.
Some common uses for 2A modified stone include:
You can find and purchase 2A modified stone from a local supplier in your area. However, choosing a reliable option is vital to ensure you get high-quality, well-graded 2A crushed stone for your PennDOT-approved projects. As a reputable supplier with over 80 years of experience, York Building Products is the go-to source for first-grade 2A modified stone that can support all your applications.

2A modified stone is a common base material for residential and commercial construction projects. The FAQs below cover what makes this stone compactable, where it performs best and other topics.
2A modified stone is “compactable,” meaning it binds tightly together under pressure, and that matters for your project because it creates a dense, stable base that resists shifting, settling and cracking over time. This foundation helps your surface hold up under heavy traffic and everyday loads.
You should use 2A modified stone instead of another crushed stone grade for your application because it delivers a compactable, dense base that holds up under heavy use. It’s the right choice for driveways, roads, paver installations and pipe bedding. If your project requires drainage or a looser fill, a different grade may suit you better.
Yes, 2A modified stone meets PennDOT specifications for road and driveway construction as a compactable subbase beneath asphalt and concrete. York Building Products produces 2A modified from crushed limestone, and we test it to confirm the material meets the grading requirements for approved residential and commercial construction.
The particle size range of 2A modified crushed stone goes from a top size of two and a half inches down to fine stone dust, making the material compactable. The varied pieces nestle together and fill gaps, giving you a tightly interlocked base that is appropriate for road construction, driveways and foundation work beneath asphalt and concrete.
Compaction of 2A modified stone affects pavement stability and longevity by locking particles together into a dense, interlocked base layer that distributes weight evenly across the surface, reducing stress on the pavement above. The result is a more stable, durable finished surface, whether asphalt or concrete, that can handle regular traffic loads and hold up over time.
Yes, 2A modified stone can be used for paver bases because it gives you a stable, level foundation beneath patios, driveways and sidewalks, for pipe bedding, because it provides consistent support for underground piping at the bottom of a trench and for road fill because it creates a stable, compactable base that asphalt and concrete bond to.
