8m asphalt paver for stone RP803 for sale

Key Features and Applications

Advanced Microcomputer Control and Leveling

The machine features independent left and right driving mechanisms governed by a new Rexroth microcomputer control system. Integrated with electronic automatic leveling technology and material level sensors, it ensures constant-speed paving and strict grade accuracy for a perfectly flat surface.

High-Efficiency Powertrain

Powered by a mature and reliable Shangchai SC7H new-generation water-cooled engine, the RP803 delivers robust power output (140 kW to 142 kW). The engine provides the high torque necessary for heavy-duty paving while maintaining low fuel consumption during continuous operation.

Durable Material Handling Components

To withstand the abrasive nature of paving materials, the material-discharging blades are crafted from highly wear-resistant alloy. Furthermore, the feeding floor and screed bottom plates utilize imported wear-resistant steel, significantly extending the service life of the material distribution system.

Hydraulic Telescoping and Heated Screed

The paver is equipped with a single-vibration, hydraulic telescoping screed that easily adjusts to accommodate different paving widths. Featuring an electric heating system, the screed prevents asphalt adhesion and delivers high pre-compaction density, improving the overall quality of the pavement.

Versatile Paving Applications

The RP803 is highly adaptable for various road construction scenarios:

• Highway Construction: Paving high-grade asphalt surface courses and stabilized base layers.

• Municipal Roads: Urban street development, avenue paving, and road widening.

• Large Infrastructure: Industrial logistics parks, port yards, and expansive parking facilities.

Technical Specifications

Dimensions and Operating Range

In its transport configuration, the XCMG RP803 measures approximately 6,680 mm to 7,040 mm in length, 3,000 mm in width, and 3,160 mm to 4,000 mm in height (depending on specific canopy and screed setups). The machine’s basic paving width can be adjusted seamlessly, expanding up to 8.0 meters to accommodate wide highway lanes. It effectively handles paving thicknesses up to 350 mm, allowing contractors to lay deep stabilized base materials or fine asphalt top courses with a single machine.
