Cold Mix Asphalt and Concrete Batching in One Plant

Polygonmach’s PVB-150 is a revolutionary dual-purpose mixing plant that functions as both a mobile asphalt plant and a concrete batching plant. This innovative model is the first of its kind – a fully mobile, dual-mode system that can produce cold mix asphalt for road repairs as well as high-quality concrete for construction, all in one compact unit. Designed and developed by Polygonmach in Turkey, the PVB-150 volumetric mixer is already proving its value on real projects (with the first unit in operation in Konya) and is poised to transform how international contractors approach on-site asphalt and concrete production. In this article, we’ll explore the PVB-150’s design, technical superiority, and why it stands alone in the market with unmatched flexibility and value.

A Mobile Asphalt Plant and Concrete Batching Plant in One

The PVB-150 serves as two plants in one: a mobile cold mix asphalt plant for producing cold asphalt or emulsion-based mixes, and a fully capable mobile concrete batching plant for on-site concrete production. This dual functionality is enabled by a unique design that supports both continuous volumetric mixing and traditional batch mixing modes within the same equipment. In asphalt mode, the PVB-150 can output up to 200 m³/hour of cold mix asphalt on demand, ideal for binder-less or emulsion-stabilized road base and patching materials. In concrete mode, it operates as a high-capacity batching plant with precise weighing and mixing to deliver uniform concrete. Contractors no longer need separate plants for asphalt and concrete – the PVB-150 consolidates both capabilities into a single mobile solution, a feature no other equipment on the market truly offers at this level.

This dual-purpose mixing plant was engineered specifically to meet the needs of modern infrastructure projects and maintenance tasks. Whether you’re patching potholes on a highway, resurfacing a road, or casting concrete for a bridge deck, the PVB-150 can adapt to the job. Polygonmach has essentially created an on-site concrete plant and a mobile road repair solution in one package. By switching modes, the same plant that produces cold asphalt for road repair in the morning can be batching fresh concrete for pavement or structural work in the afternoon. This kind of versatility and multi-functionality (including use as a soil stabilization mixer or cement-treated base plant) is unprecedented, giving contractors a new level of flexibility at the jobsite.

Innovative Dual-Purpose Design and Technical Superiority

Polygonmach’s PVB-150 is not a repurposed concrete plant with add-ons, but a ground-up innovative design built for dual-purpose use. At its heart is a high-performance twinshaft pugmill mixer that ensures thorough and consistent mixing of materials. Driven by a powerful 7.5 kW motor and synchronized by a robust cogged gear system, the twinshaft mixer prevents any chance of desynchronization between its shafts. It is equipped with durable Hardox 450 alloy mixing paddles and SKF bearings with automatic lubrication, guaranteeing long-life, reliable operation under continuous use. The mixer’s dimensions (1,000 × 2,050 mm) are engineered for optimal blending efficiency, whether mixing aggregate with bitumen emulsion for cold asphalt or cement and gravel for concrete. This level of engineering precision in the mixing module gives the PVB-150 a clear technical edge, delivering homogeneous mixes batch after batch.

Another pillar of the PVB-150’s technical superiority is its high-precision weighing and dosing system. The plant employs a subtractive weighing technology for its aggregate bins and cement hopper, which ensures extremely accurate batching of materials by weighing what is discharged rather than what is loaded. Three aggregate hoppers (each 8 m³ capacity) sit atop belt feeders, and each hopper is lined with low-friction liners and equipped with vibrators and safety grids. This setup guarantees consistent flow of aggregates and prevents clogs. The aggregate dosing is inverter-controlled for precise flow regulation. On the cement/binder side, the PVB-150 integrates a 6,000 kg cement silo (approx. 5–6 tons capacity) complete with dual screw conveyors and high-accuracy load cells. This cement/binder hopper can handle ordinary cement for concrete or store binding agents like bitumen emulsion or cement dust for cold mix asphalt, with equal precision in dosing. In addition, the plant includes additive tanks (3 × 50 L) with flowmeters and dosing pumps for admixtures or liquid additives, and a water dosing system featuring a 5.5 kW pump (delivering up to 30 m³/h flow) with flowmeter control for exact water metering. All of these components work in concert to ensure that whether in asphalt or concrete mode, the mix proportions are spot-on for each recipe, eliminating guesswork and enhancing quality control.

Mobility and Rapid On-Site Setup

One of the PVB-150’s greatest advantages is how mobile and easy to deploy it is, especially considering its dual functionality. The entire plant is built on a road-legal, two-axle trailer chassis that can be towed to site with a standard truck tractor – no special transport permits required. All components of the mixing plant (hoppers, mixer, conveyors, silos, etc.) are mounted on this single trailer frame in a compact layout for transport. This ultra-mobile design makes relocation between job sites fast and cost-effective. Contractors who frequently move between project sites or highway maintenance crews doing spot repairs will appreciate that this mobile construction plant can follow them wherever needed.

Setting up the PVB-150 on a new site is remarkably quick and hassle-free. The trailer is equipped with hydraulic self-erecting support legs, which allow the plant to lift and set itself upright without the need for a crane. At the push of a button, the hydraulically actuated legs will level and stabilize the unit, and can even unfold certain components into working position. This self-erecting feature dramatically reduces installation time and cost, enabling full setup within hours or even minutes instead of days. In fact, Polygonmach notes that the PVB-150’s mobile frame with self-lifting chassis can be ready for operation in as little as 10 minutes after arriving on site. No extensive foundations are required – the plant can operate on any firm, relatively level ground without special civil works. Additionally, since it’s trailer-mounted and compact, it can squeeze into confined or urban job sites that would be inaccessible to large stationary plants. This ease of transport and setup gives contractors tremendous logistical flexibility: they can batch concrete on-site at a remote project in the morning, then relocate and produce cold mix asphalt for a road repair in the afternoon, all with the same equipment.

Once on site, the PVB-150’s mobility features continue to shine. The discharge conveyor is hydraulically adjustable, so you can directly feed mix into a dump truck, paver, or concrete pump hopper as needed, at various heights. When the job is done, teardown is equally swift – conveyors and legs fold up, and the unit is ready to tow to the next location. This stands in stark contrast to traditional fixed asphalt plants or stationary concrete batching plants, which can take days to disassemble and weeks to re-assemble at a new site (if they’re even movable at all). With the PVB-150, “your site becomes your plant”, eliminating material transport delays and increasing productivity.

 The above technical specs underscore how the PVB-150 packs full-scale plant performance into a mobile format. For instance, having 3×8 m³ aggregate bins and a 6-ton cement silo on a trailer is a significant capacity, allowing continuous production without constant refilling. The inclusion of an onboard generator and hydraulic erection system speaks to the focus on independence and quick logistics. Everything about the design aligns with the goal of maximizing flexibility and efficiency on-site.
