Caterpillar RM500B Recycler Review: Build Your Next Road Project from the Base Up

The next chapter of a road can begin with the material already beneath it. For contractors planning pavement reclamation or soil stabilisation, this Caterpillar RM500B offers a machine worth exploring—with an 8-foot working width, a supplier-listed water system and a rebuilt-engine description.

About this review: This article assesses supplier information, original photographs and Caterpillar’s model documentation. We have not inspected or operated the machine. Details were checked on 17 October 2026; confirm the selected unit and current quotation with the supplier.

A road recycler with a clearly defined role

Caterpillar describes the RM500B as a rotary mixer for full-depth reclamation and soil stabilisation. In practical terms, it belongs in the discussion when a project calls for processing existing pavement materials or mixing soil as part of an engineered treatment plan.

Omnia’s matching offer identifies this machine as a used, 2015 RM500B, stock US2366. Its advertised asking price is US$170,000. That gives your enquiry a specific starting point: one machine, one reference and a project brief the supplier can respond to.

Caterpillar RM500B specifications at a glance

Unit details: the advertised marketplace offer and Omnia’s matching US2366 machine record. These are advertised specifications, not independent measurements.

Turn the working dimensions into a useful project enquiry

The listed 8-foot width is approximately 2.44 metres. Use that figure when discussing treatment lanes, pass overlaps and access with your project team. Think about the actual work area: a long open run, a narrow section or a sequence of separate treatment zones each calls for a considered operating plan.

The advertised maximum working depth is 18 inches, approximately 457 mm. Your required treatment depth should come from the project design. Give the supplier the material type and specified depth, then confirm the fitted rotor and tools for that application. Maximum depth is a specification; the finished result also depends on the material, setup and treatment process.

A C15 engine and water system: focus on the quoted configuration

The offer specifies a CAT C15 ACERT Tier 3 engine and describes the engine as rebuilt. Request the rebuild scope, date and supporting records so the purchase documents capture exactly what is being supplied.

Power figures explained: Omnia advertises 548 HP; the marketplace pairs that figure with 403 kW. Caterpillar’s RM500B LRC documentation expresses 403 kW as 540 hp gross under SAE J1995. Confirm the rating basis for this unit from its engine records when comparing quotations.

The seller also lists a water system. For your enquiry, specify the treatment process and ask for a demonstration of its controls and delivery arrangement. Have the responsible project team establish the mix design and water requirement before selecting operating settings.

Model context: Caterpillar’s RM500B LRC documentation. Model information provides context; the written quotation should identify the equipment fitted to stock US2366.

See the advertised machine in the original photos

The supplier photographs show the yellow RM500B, glazed cab, large rubber tyres and machine body from several angles. Use these views to prepare questions about access, controls and the equipment included in the sale.

Request a working video and inspection

For a useful video request, quote US2366 and ask for a current walkaround showing the serial plate, operating-hours display, start-up and relevant operating functions. Ask the supplier to include the water system and explain the fitted rotor configuration. Omnia’s FAQ says it can provide working videos and arrange OEM or independent inspections. Agree the scope for this machine before finalising an order.

Product location and worldwide delivery

Product location: North Carolina, USA. Omnia’s detailed stock page and the matching marketplace description identify that state. Use the confirmed collection point when arranging a visit or requesting haulage.

The supplier advertises worldwide shipping. Its product page also mentions customs paperwork and regular shipping updates. The shipping service covers documentation assistance, marine-insurance arrangements and shipment coordination. A destination-specific quote is needed to confirm service to your country, port or final site.

The advertised weight is 60,000 lb, approximately 27.2 tonnes. Request the actual shipping weight and transport length, width and height for the agreed configuration. Include the destination and access conditions in your enquiry so the supplier can identify the appropriate inland haulage, loading arrangements and sea-freight method where required.

Delivery sources: Omnia’s shipping services and purchase and shipping FAQ. Worldwide shipping is a general service statement; confirm the route and agreed delivery point for your order.

Shipping costs and order terms to confirm

Omnia’s published standard terms place transport costs with the customer and identify freight, packing, insurance, taxes and applicable duties as additional costs. They also allocate loading or unloading resources at the delivery point to the customer and address import/export permissions. Ask for an itemised quotation showing which services and charges are included.

The FAQ describes wire transfer before shipment, with Letters of Credit or Cash against Documents available in some circumstances. It also describes a negotiable 30-day reservation using a 10% deposit and weekly shipment updates.

The standard terms separately state a 10% non-refundable deposit and balance within 14 days of the pro forma invoice. Those published terms refer to sterling, while this US machine is advertised in dollars. Confirm the contracting entity, currency, deposit conditions, payment schedule and applicable delivery terms in writing.

For acceptance planning, the FAQ states that Omnia does not provide a warranty on used machinery. Agree the inspection arrangements and applicable sale terms for the selected unit.

Commercial reference: Omnia’s standard terms, particularly sections 4, 6, 8 and 9, read alongside the supplier FAQ and your unit-specific quotation.
