Lava Rock vs Recycled Asphalt
Side-by-side comparison of Lava Rock and Recycled Asphalt to help you choose the right gravel for your project.

Lava Rock
Lava rock is a lightweight, porous volcanic stone commonly used in landscaping. Its rough texture helps retain moisture while allowing airflow to plant roots.
Recycled Asphalt
Recycled asphalt is made from reclaimed asphalt pavement that has been crushed and screened. When compacted, it hardens over time as residual asphalt binder reactivates, creating a durable and cost-effective driving surface.
