Asphalt plants come in two configurations: stationary and portable. The right choice depends on your production volume, how often you move between locations, and your site setup. Stationary plants are built for high-volume, fixed-location production. Portable asphalt plants are designed to be relocated between job sites while still producing high-quality hot mix asphalt. Understanding the difference helps you size and configure the right plant before you build.

What is a Stationary Asphalt Plant?
Stationary drum mixers are often bigger than their mobile counterparts. They require more space to set up and are usually stationed at a single location for an extended period. The purpose of a stationary plant is to produce large quantities of hot mix at a single location.
Stationary plants are usually more complex than their mobile version. These plants require more permanent foundations and preparation, as the components’ weight can be much greater. Additionally, transportation costs are often higher because stationary plant components must be trailered. This typically results in an oversized/overweight load.
The Advantages of Stationary Plant
A properly operating stationary plant is more efficient than a mobile plant. This is the result of the output being higher and generally located near a reliable, cheaper fuel supply. Stationary plants tend to have a heavier build and greater robustness, as they are designed to remain in place for a long period without needing to be transported every few weeks or months.
- Capacity. Higher output capacity suited to sustained, high-volume production
- Longevity. Heavier, more robust construction designed for long-term fixed use
- Fuel Cost Savings. Generally located near a reliable fuel supply, lowering operating costs
- Transportation Cost Savings. Lower per-ton transportation costs once installed
- Customization. Greater flexibility for customization and add-on components
What is a Portable Asphalt Plant?
A mobile or portable mixing plant can also produce quality hotmix on a smaller scale. The primary factor distinguishing a stationary from a portable plant is the maximum physical size. Mobile plants are much more compact and need to be transported down the road several times a season. They are often the best choice for temporary projects or remote locations.
The Advantages of a Mobile Asphalt Plant
- Mobility. They are typically smaller and use fewer components, making them easier and cheaper to transport, with an integral highway axle design.
- Use Less Space. Mobile plants have smaller components that are tightly packed, requiring less space.
- Less Installation time. The overall size is smaller, weight is less, and minimal foundation prep is required to operate a portable plant. It can be installed in a shorter timeframe, making it ideal for shifting locations and limited space. Most portable mixing plants are prewired, facilitating faster installation.
- Lower costs. When facilitating temporary projects, mobile plants use smaller components, less space, and require less installation time. This results in lower setup and operating costs than a stationary unit.
In general, if you need a plant that can be quickly installed and shipped from site to site, you’ll want a portable version. A stationary version, on the other hand, is the better choice for customers with a high volume of hotmix production at a single location.
CWMF designs and builds both stationary and portable hot mix asphalt plants, sized from 200 to 600 tons per hour to match each operation’s production goals. Our Revolution D™ portable plant is engineered for producers who need flexibility without sacrificing output. Our stationary plants are built for long-term, high-volume production with the same heavy-duty design standards. With more than 30 years of plant design experience, we work directly with producers to configure the right plant for their site, production requirements, and budget.

More FAQs About Stationary vs. Portable Asphalt Plants
What is the difference between a stationary and portable asphalt plant?
A stationary asphalt plant is permanently installed at a fixed location and designed for high-volume, long-term production. A portable plant is built to relocate between job sites and is better suited for temporary projects, remote locations, or producers who work across multiple sites.
How do I know what size asphalt plant I need?
Plant size is typically measured in tons per hour (TPH). The right TPH rating depends on your production volume, project types, and site requirements. CWMF builds plants from 200 to 600 tons per hour and works directly with producers to size and configure the right plant for their operation.
What is the CWMF Revolution D™ portable plant?
The Revolution D™ is CWMF’s portable drum mixer plant, designed for producers who need flexibility without sacrificing production quality. It is available in multiple configurations and is engineered for efficient transport and fast setup between locations.
Is a portable asphalt plant as capable as a stationary one?
Portable plants produce quality hot mix asphalt but at a smaller scale than most stationary plants. They are optimized for flexibility and fast installation rather than maximum throughput. If sustained high-volume production at a single location is the priority, a stationary plant is typically the better choice.
Can CWMF build a custom asphalt plant for my operation?
Yes. CWMF designs and builds complete hot mix asphalt plants to order, working with producers to evaluate production goals, site requirements, and budget before recommending a configuration. Contact us to discuss your project.
