Road Crush

Road Crush is a term used for a mixture of gravel and fines. Used primarily in road building, it is a durable aggregate that compacts extremely well. FT Aggregates manufactures a Premium Road Crush that boasts some of the highest 2 face fracture counts and compaction rates in the industry. The better an aggregate compacts and locks together, the stronger the base becomes.

Road Crush can go by many names; aggregate base, base course, base material, driveway gravel, sandy gravel, crushed gravel, crushed rock, and many more. There are many different types of road crush, each with a different purpose. When prepping an area for a gravel pad it is recommended that a different material be used than that is used resurfacing a county road. Road crush can be used for almost anything that requires a stable base; retaining walls, driveways, county roads, a base material for asphalt roads, compaction material for concrete footings, laying paving stones, and so much more.

Most municipalities will have their own sieve specification or gradation for construction projects in the area. Roadways, hiways, and bridges will often fall under different specifications. In Alberta, the governing body is Alberta Transportation. Aggregates are manufactured to very precise specifications determined by the customer’s tender documents. These products are not interchangeable with aggregate material that does not meet specifications.
