Dump Truck Gravel Capacity Guide: How Many Cubic Yards Can Different Trucks Hold

Planning a gravel project and wondering how much material you can haul in one trip? You’re not alone. Most homeowners and contractors face this same question when estimating delivery costs and project timelines.

Standard dump trucks hold 10-12 cubic yards of gravel, while super dumps can carry 14-16 cubic yards. Large articulated and belly dump trucks handle 25-32 cubic yards. The exact capacity depends on truck type, gravel density, and local weight restrictions.

Quick tip: Always check your local DOT weight limits before loading. Exceeding axle weight restrictions can result in hefty fines and safety hazards.

Understanding these capacities helps you plan better, save money on multiple trips, and ensure your project stays on schedule. Let’s break down everything you need to know about dump truck gravel capacity.

Understanding different dump truck types and their capacities

Not all dump trucks are created equal. The type you choose dramatically affects how much gravel you can transport in a single load.

Standard dump trucks are your most common option, typically holding 10-12 cubic yards. These work well for residential driveways, small landscaping projects, and light commercial work. You’ll find these trucks easy to maneuver in tight spaces and neighborhoods.

Super dump trucks step up the game with 14-16 cubic yard capacity. They’re perfect for medium-sized projects like parking lots or larger driveways. The extra capacity means fewer trips and lower overall delivery costs.

Articulated dump trucks are the workhorses for off-road projects, carrying around 25 cubic yards. Their articulated design helps them navigate rough terrain that would challenge standard trucks. Think construction sites with unfinished roads or remote locations.

Belly dumps and end dumps represent the heavy-duty category, hauling 29-32 cubic yards of material. These massive trucks work best for large commercial projects, road construction, and major landscaping jobs.

Factors that affect how much gravel you can actually haul

Capacity numbers tell only part of the story. Several factors determine how much gravel your truck can safely carry.

Weight restrictions top the list of limiting factors. Most states limit axle weights to prevent road damage and ensure safety. A truck might have space for 15 cubic yards but can only legally carry 12 cubic yards of dense gravel due to weight limits. Understanding how much weight dump trucks can hold is crucial for staying compliant with regulations.

Gravel type and moisture content significantly impact capacity. Dry pea gravel weighs much less than wet crushed stone. Rain-soaked gravel can add 20-30% more weight, forcing you to reduce volume to stay within legal limits.

Road conditions and travel distance also matter. Longer hauls over rough roads require more conservative loading to prevent shifting and maintain vehicle stability. Urban routes with low bridges or weight-restricted roads may further limit your options.

Important note: Always factor in a 10-15% buffer for settling and compaction. Gravel naturally settles during transport, so you’ll need slightly more material than your calculations suggest.

Calculating gravel volume and weight for your project

Getting your calculations right saves time, money, and prevents multiple delivery trips. Here’s how to estimate your needs accurately.

Start by measuring your project area in feet. Multiply length times width times desired depth to get cubic feet. Divide by 27 to convert to cubic yards. For example, a 20-foot by 30-foot driveway with 4-inch depth needs about 7.4 cubic yards.

Account for gravel density when estimating weight. Crushed stone weighs roughly 1.3 tons per cubic yard, while pea gravel weighs about 1.7 tons per cubic yard. These weights help determine if you’ll hit truck weight limits before reaching volume capacity. If you’re wondering whether a dump truck can carry 20 tons, the answer depends on the truck configuration and local regulations.

Factor in waste and compaction by adding 10-15% to your calculated needs. Gravel settles over time, and some material gets lost during transport and spreading. This buffer ensures you have enough material to complete your project properly.

Consider access limitations at your site. Can large trucks navigate your driveway or street? Sometimes smaller trucks making multiple trips work better than one large delivery that can’t reach your project area. Before scheduling delivery, you might want to read about whether a dump truck can drive on your driveway to avoid potential damage.

Safe loading and transport practices

Proper loading techniques protect your investment and ensure everyone’s safety during transport and delivery.

Load distribution matters more than total volume. Spread gravel evenly across the truck bed to prevent tipping and maintain vehicle stability. Avoid piling material too high, which creates wind resistance and shifting risks. The number of axles on your truck affects weight distribution—learn more about how many axles a dump truck has and why it matters.

Secure your load with tarps or netting, especially for longer hauls. Flying gravel damages other vehicles and creates liability issues. Most professional haulers include load securing as standard practice.

Plan your route carefully, avoiding weight-restricted bridges and low overpasses. Check local regulations for oversized loads, which may require special permits or escort vehicles for the largest dump trucks. If you’re operating commercially, make sure you understand whether your dump truck needs a DOT number for compliance.

Communication with your driver ensures smooth delivery. Discuss site access, unloading location, and any obstacles beforehand. Clear communication prevents delays and potential property damage during delivery.

Understanding dump truck gravel capacity helps you make informed decisions for your project. Whether you need a standard 10-yard truck for your driveway or a massive belly dump for commercial work, matching truck size to project needs saves money and ensures timely completion. Remember to factor in weight restrictions, gravel type, and site access when planning your delivery. With proper planning and the right truck choice, you’ll have exactly the amount of gravel you need delivered safely and efficiently.
