How Aggregates Are Transported 

Aggregates are transported to the point of use. The preferred method of transportation depends on a wide variety of factors, including delivery and schedule requirements, distance to the site, volume of material to be delivered, loading and unloading facilities, and the availability of different transportation methods.   

By Truck  

Transportation by truck is the most common method. Trucks can quickly be loaded at our locations and can dump or drop their loads unassisted at the destination. They can deliver practically anywhere there is a road. From small pickups to tractor trailer rigs, trucks are filled to match their weight load requirements, making deliveries more economical.

Transporting materials at the mine site can be completed by utilization of a haul truck. Haul trucks are never driven on public use roads. Depending on the size of the haul truck, they can carry between 30 to 90 tons of stone. Haul trucks move the rock to the jaw crusher of the plant, conveyor belts and stock piles. The wheels of the truck can be 8 to 12 feet high. Two pickup trucks could hide in the bed of a large haul truck. A driver sitting in the cab of the truck would be approximately fifteen feet off the ground.

Deliveries to customers are generally handled by smaller ”dump” trucks. Dump trucks can carry up to 22 tons of material per truck. Our scale operators help to enforce weight laws by making sure trucks do not leave the scale overweight.

By Rail

Rail shipping may be more economical than truck transport. Typically, rail shipment is used to transport stone to areas of the country where the quality of the local stone product is poor, or they have limited natural stone resources available locally. Aggregates can be loaded into either 100-ton bottom dump hopper cars, gondolas, or moved in a single car.

By Water  

When a quarry has access to a navigable river, aggregate can be moved by hopper or flat deck barges. Hopper barges commonly hold 1,500 tons of aggregate.
