BOMAG launches the BW 18 RH, an 18-tonne pneumatic roller compactor that positions itself in the intensive compaction segment for road construction projects. The machine stands out for its optimized ballasting concept and advanced compaction technology. It targets road construction companies seeking maximum performance with reduced maintenance.
A self-weight of 18 tonnes to eliminate ballasting
The BOMAG BW 18 RH has an operating weight of 18,000 kg, which is its main selling point. This mass allows compacting thick asphalt layers without adding extra ballast. For companies, this means fewer handling operations, less downtime, and faster implementation on site. The oscillating chassis ensures even load distribution across both tire trains, even on uneven terrain.
The standard configuration includes nine tires at the front and eight at the rear, all with a width of 280 mm. This asymmetrical arrangement ensures complete surface coverage without uncompacted zones. Tire pressure can be adjusted between 2 and 8 bars depending on material and layer thickness, offering flexible use suitable for bituminous asphalt as well as base layers.
VARIOMATIC vibration system for targeted compaction
The machine integrates the VARIOMATIC system from BOMAG, which automatically adjusts vibration frequency and amplitude based on the degree of compaction achieved. Onboard sensors continuously measure material stiffness and adjust vibration parameters to prevent over-compaction or under-compaction. This system reduces the number of passes needed and improves productivity on asphalt construction sites.
Vibration amplitude can reach 2.1 mm in intensive mode, with maximum centrifugal force of 105 kN. Frequency varies from 28 to 41 Hz depending on the selected work mode. These values place the BW 18 RH in the upper segment of pneumatic compactors for deep compaction of base and binder layers. The operator can also switch to static mode for delicate finishing without vibration.
Automatic documentation and integrated telematics
The BW 18 RH features the BOMAG ECONOMIZER documentation system, which automatically records compaction parameters (temperature, number of passes, frequency, amplitude) and geolocalizes them via GPS. This data is transferred in real-time to the BOMAG CONNECT fleet management platform, allowing the site manager to remotely verify work progress and compliance with technical specifications. This level of traceability is becoming essential on major road projects subject to rigorous quality controls.
The system is compatible with 3D GPS control, enabling integration into BIM workflows for complex road projects. Compaction data can be exported in standard format to feed project management systems or meet ISO certification requirements.
EU Stage V engine and optimized consumption
The machine is equipped with a Deutz diesel engine rated 115 kW (156 hp) compliant with the EU Stage V standard. The exhaust aftertreatment system combines a particulate filter and SCR catalyst with AdBlue injection. BOMAG reports fuel consumption of 12 liters per hour during standard operation with active vibration, approximately 15% less than the previous generation thanks to hydraulic optimization and variable engine speed.
The 260-liter fuel tank ensures over 20 hours of autonomy under intensive use, reducing refueling stops on large construction sites. The 25-liter AdBlue tank provides proportional autonomy, with a diesel/AdBlue consumption ratio of approximately 10:1. Maintenance of the pollution control system is simplified by extended service intervals up to 1,000 operating hours.
Cabin ergonomics and perimeter visibility
The air-conditioned ROPS/FOPS cabin offers a glass surface of 4.2 m² for 360-degree visibility over the compaction zone. The pneumatically suspended seat reduces vibrations transmitted to the operator, in compliance with European occupational health standards. Controls are grouped on a multifunctional armrest with integrated joystick for controlling vibration, water spray, and steering.
The 7-inch color screen displays compaction parameters, maintenance alerts, and GPS mapping of the treated area in real-time. A standard rear-view camera facilitates reverse maneuvers, essential when compacting in tight strips on motorway projects. Perimeter LED lighting enables night work, common on road construction sites subject to daytime traffic restrictions.
Competition and price positioning
The BW 18 RH competes with segment references: the HAMM GRW 18i and Caterpillar CW34. The list price shown in Germany starts at approximately €285,000 net in base version, with an additional €15,000 for advanced telematics and automatic documentation. This pricing positions itself in the upper-middle market segment, justified by complete standard equipment and adaptive compaction technology.
For companies already operating BOMAG compactors, integration into the existing CONNECT platform represents a customer retention argument. Operating costs are announced at around €65 per operating hour (fuel, AdBlue, preventive maintenance), based on manufacturer calculations for 1,500 annual hours.
Availability and distribution network
BW 18 RH production started at the BOMAG plant in Boppard, Germany in the first quarter of 2024. First deliveries to France are scheduled for the second quarter through the Wirtgen Group dealer network. Lead times are 12 to 16 weeks depending on selected options. A spare parts inventory is being built in regional centers to ensure availability under 24 hours for critical components such as hydraulic cylinders and vibration sensors.
BOMAG offers an extended CARE maintenance contract including scheduled services, telematics, and parts warranty up to 5,000 hours for an annual fee of €8,500. This formula aims to secure total cost of ownership (TCO) over the typical 8 to 10 year lifespan of an asphalt construction compactor in a public works equipment fleet.
