Qual a diferença entre o betão betuminoso e o revestimento misturado com plantas?
Jul 13, 2025
In road construction, two common materials dominate the scene: plant-mixed surfacing and traditional asphalt concrete. While they may appear similar at first glance, their composition, application methods, and performance differ significantly. For contractors, understanding these differences is essential—not only for optimal project performance but also for choosing the right asphalt mixing plant or block machine manufacturer.
SL Machinery is committed to equipping infrastructure developers with reliable, high-output machines that fit the demands of modern paving. Whether you’re considering an central de asfalto para venda or exploring different material solutions for your next project, it’s essential to know what sets plant-mixed surfacing apart from standard asphalt concrete.

What Exactly Is Plant Mixed Surfacing?
Plant mixed surfacing is a blend of aggregate and bitumen that is first processed in a road- building plant such as an advanced asphalt plant. The words are employed to specify that the pre-mixed pavement materials meet particular requirements for performance, and they differ from field-blended alternatives.
One of the key benefits of the process is that it provides temperature control, consistent mix quality, and better adhesion properties. This kind of material is a very common option for the topmost layers of the roads that will have high abrasion and will be free from rutting and water damage problems. The plant mixed surfacing production process, in comparison with on-site asphalt concrete such as here, is more standardized, and, typically, some or all of the feedstocks are modified by polymers.
How It Differs from Conventional Asphalt Concrete
- Mixing Location:
Asphalt concrete can sometimes be blended partially on-site, while plant mixed surfacing is entirely mixed at the factory. - Material Composition:
Plant mixed surfacing allows for the integration of advanced modifiers and finer grading control. - Controlo de qualidade:
Factory mixing ensures stricter control over temperature, binder ratio, and moisture content. - Application Thickness:
Plant mixed materials are often used for thinner, more refined surface courses; asphalt concrete is generally used in base layers. - Durabilidade:
With additives and better mixing, plant mixed surfacing can outperform traditional asphalt in terms of water resistance and load-bearing capacity.
The Role of the Asphalt Mixing Plant
The distinction in performance between these materials ultimately comes down to how they’re produced—and that means choosing the right equipment. At Maquinaria SL, we specialize in asphalt mixing plants that deliver high-quality mixes for both types of surfacing materials.
A modern central de mistura de asfalto enables:
- Precise control of aggregate sizes and proportions
- Integration of anti-aging agents and polymers
- Energy-efficient drying and heating systems
- Automated batching and real-time monitoring
With the right setup, contractors can meet road authority specifications for both plant mixed surfacing and asphalt concrete, all while improving cost-efficiency.
Why Machinery Choice Matters
Some project developers may overlook the impact that a machine has on road performance. However, using outdated equipment or poorly configured systems can result in uneven binder distribution, temperature inconsistencies, or premature cracking of pavement.
That’s why SL Machinery, as a trusted fabricante de máquinas de blocos and asphalt solutions provider, offers tailored systems that improve mix stability, batch consistency, and ultimately, pavement lifespan. Whether you are seeking an asphalt plant for sale or upgrading from manual operations, we offer full production line customization and overseas support.

Think Beyond Asphalt—Think Quality at the Core
What exactly is the difference between Plant Mixed Surfacings (PMS) and Asphalt Concrete (AC)? In fact, it is not only the materials that are different, but the system of production as well as the facilities and procedures are the machines involved. Choosing SL Machinery, you will not only purchase the best asphalt plant — you are securing for continuous, quality products, and long-lasting roads.
