In the field of road construction machinery, the RP603 asphalt paver stands out as a benchmark for innovation and efficiency. But what exactly makes the RP603 the go-to choice for contractors and engineers worldwide? Let’s go deep into its features, advantages and applications and find out the answer.
What is the RP603 asphalt paver?
The RP603 is a state-of-the-art asphalt paver engineered to lay asphalt road surfaces with precision and speed. It is a versatile piece of road construction machinery capable of handling a wide range of paving tasks, from small urban roads to large highway projects.
Unique Advantages
1.Precision Paving
The RP603 boasts a laser+ultrasound dual-leveling system that ensures a positioning error of no more than±0.5 mm (National Engineering Machinery Quality Supervision and Inspection Center test data). The RP603 features a laser+ultrasonic dual-leveling system, achieving a positioning accuracy of ≤±0.5 mm (tested by the National Construction Machinery Quality Supervision and Inspection Center).
2.High Efficiency
The actual engineering test result of RP603 in the expressway construction scene is 350 tons per hour, which is 17% higher than the industry average. This is equivalent to saving as much as $ 1,100 per year), which further improves the cost-effectiveness.
3.Temperature Elasticity
The engine of RP603 can run in temperatures range of -40℃ to 120℃ (low temperature start-up test in the laboratory: the success rate of start-up at -40℃ is 100%). Its hydraulic oil can work effectively between -30℃ to 80℃, ensuring reliable performance in extreme weather conditions.
4.Energy Efficiency
According to the laboratory comparison test, RP603 only consumes 25 liters of fuel per hour, which is 12% higher than its competitors’ fuel efficiency. This not only reduces operating costs, but also reduces the carbon emissions.
5.Durable parts
The spiral distributor of RP603 has a WC-Co alloy wear-resistant layer, and its service life is three times longer than that of ordinary steel. Its high-frequency vibration system, equipped with SKF high-temperature bearings, ensures continuous operation for up to 8,000 hours (third-party durability testing).

Major application occasions
1.Highway Construction
The RP603 is ideal for laying asphalt road surfaces on highways, where speed and precision are paramount.A provincial highway group reduced rework rates from 8% to 1% using the RP603, finishing a 100km project 5 days early (XCMG Case Study, 2023).（Source：https://www.xcmg.com/）
2.Urban Road Renovation
In urban areas, where space is limited and traffic disruption must be minimized, the RP603’s compact design and precise control systems ensure smooth operation without compromising on quality.
3.Airport Runway Construction
The RP603’s ability to achieve high flatness and compaction rates makes it suitable for constructing airport runways, where even minor imperfections can pose safety risks.
Common problems
Q 1: How to troubleshoot the leakage of hydraulic system of RP603?
A: First of all, check the seal at the joint of the hydraulic pump and the pipeline. If the seal is aging (which is common in equipment used for more than 2 years), replace it with fluororubber seal (model: YXD-40) that can withstand 150℃. Next, check whether the high-pressure hoses is damaged, and replace it with original high-pressure hoses (part number: XGRP-001) with the rated pressure of 31.5 MPa. After replacement, start the equipment and run it with no load for 10 minutes to confirm that there is no leakage.
Q 2: What should I do if aggregate segregation occurs during paving process using RP603?
A: First, reduce the paving speed (from 5m/minute to 3-4m/minute). Second, increase the rotating speed of the auger (from 120 rpm to 150 rpm). Third, check the material level to ensure that it covers two thirds of the spiral blades. If separation of fine bone material occurs, the high frequency mode (frequency 45-50 Hz) of the vibration system is activated. Usually, you can see the improvement within 5 minutes after adjustment.
Q 3: What should I do if RP603 fails to start at low temperature (-25℃)?
A: First, check the engine preheating plug (located on the side of the engine cylinder block). If the preheating plug has no power, replace it with a 24 v preheating plug (model: GL-24). Second, fill the fuel tank with -35 diesel oil and exhaust the air from the fuel pipe. Third, activate the hydraulic oil electric heating tape (press the “preheat” button on the control panel) and preheat for 10-15 minutes until the hydraulic oil temperature reaches ≥ 5℃ before starting the equipment. Fourth, after starting, let the engine run at idle speed for 5 minutes, and then enter the running mode.
Q 4: Does the RP603 support the use of different types of bone materials for paving? Do I need to change any components?
A: Yes, the RP603 supports the use of various bone materials such as asphalt, water-stable base and crushed stone for paving. For paving asphalt, there is no need to change components; Just adjust the vibration frequency to 40-50 Hz and the paving speed to 3-5 meters/minute. For paving water-stable base course (aggregate size ≤ 20 mm), replace the wear-resistant lining plate of the spiral distributor (part number: XGRP-002, which is more wear-resistant) and adjust the vibration frequency to 30-40 Hz. There is no need to replace the core components as a whole; It only takes 1 hour to replace the liner (operated by two people).
Conclusion
In conclusion, the RP603 asphalt paver is a top-tier piece of road construction machinery that offers unmatched precision, efficiency, and resilience. Its advanced features and versatile applications make it the ultimate solution for a wide range of asphalt road projects. Whether you are building a highway, renovating an urban road or building an airport runway, the RP603 will help you easily achieve outstanding results.
