In the dynamic world of road construction machinery, efficiency, accuracy and adaptability are not only fashionable words, but also the cornerstones of successful implementation of project. With the acceleration of urbanization and the surge in demand for infrastructure, the demand for compact and high-performance asphalt pavers is unprecedented. Enter the RP 355, a small road asphalt paver, which aims to innovate narrow road construction, urban transformation and challenging environment. But is this the right choice for your next project? Let’s dive into its features, advantages, and real-world applications to find out.
What Is the RP355 Small Road Asphalt Paver?
RP 355 is a compact crawler asphalt paver, which aims to provide high-performance paving in places where traditional machinery can not work. With a working width ranging from 0.5 m to 3.5 m, this machine combines the flexibility of a small-scale device with the power and precision of larger models. Its compact design, full hydraulic drive system and intelligent control panel make it an ideal choice for a wide range of applications, from rural road upgrading to urban back street renovations.Compact pavers like the RP355 reduce labor costs by 15–20% compared to manual methods (Source:https://cea.org.uk/)
Why Choose the RP 355 Over Other Road Construction Machinery?
1. Laser-Guided Precision for Superior Flatness
The RP 355 is equipped with a laser leveling system, achieving a positioning error of ≤ 0.8 mm (detected by the National Construction Machinery Quality Supervision and Inspection Center in 2024). This ensures that the flatness error of asphalt pavement is ≤ 3 mm/3 m, even in the process of continuous paving with a width of 3.5 m. Traditional models often struggle with uneven material distribution, resulting in expensive rework.
2. All weather performance
· Extreme cold (-35℃ to-15℃): the engine preheating system of RP 355 reduces the start-up time to 5 minutes, while competitors need 30 minutes. This extends daily operation time by 30%, which is a key advantage in cold areas.
· Extreme Heat (≥45℃): A single-stage aluminum radiator (1.8㎡) maintains hydraulic oil temperatures ≤80℃, while NBR seals resist degradation.
· High humidity (≥ 95% RH): Corrosion-resistant coatings and IP 65 electrical boxes can prevent rust and moisture.
3. Fuel Efficiency and Cost Savings
The road asphalt paver RP 355 consumes 18 liters/hour of diesel, which is 10% less than that of competitors (20 liters/hour). In addition, its low maintenance design reduces the annual maintenance costs to 600 pounds, while the competitor’s model is 900 pounds.
4. Endurance and longevity
Key components like the spiral distributor and vibratory motor are rated for 6,000 hours of operation, outlasting competitors by 33%. The MTBF (Mean Time Between Failures) is 4,000 hours, minimizing downtime.

Primary Applications of the XCMG RP355 Asphalt Paver
1.Rural highway Construction
The road asphalt paver RP 355 is a game-changer for rural road upgrades, particularly in initiatives like China’s “Four Good Rural Roads” project. It can pass through narrow spaces and provide high-quality paving materials, which is an ideal choice for upgrading county highways. In a case study in Jiangsu Province, the use of three RP 355 machines reduced paving time by 30%, achieving 97% compaction on 3.5 m-wide roads and earning the project the title of “High-Quality Rural Road.”
2. Urban renewal
From backstreet repairs to sidewalk renovations and pipeline-covered area restorations, the RP 355 excels in urban environments. Its low noise operation allows working in residential areas at night without disturbing residents, as demonstrated in the old city reconstruction project in Shanghai.
3. Professional environment
The road asphalt paver RP 355 is also well-suited for specialized projects such as stadium construction, industrial park development, and tourist site renovations. It can operate in a temperature range of-35 c to 110 c without loss of performance, ensuring reliable performance in extreme weather.
Aase Study
A county transportation company faces the challenges of traditional pavers: uneven material distribution leads to “wave mode”, and start-ups in cold weather delay the projects by 30%. After switching to three XCMG RP 355 units, they achieved.
1. Flatness error reduction: 5 mm/3 m → 2.5 mm/3 m (without rework).
2. Daily running time increased: 6 → 9 hours.
3. Project completion time: 6 days in advance.
4. Cost savings: 9% (including rework and shutdown time).
Common problems
Q1: The hydraulic oil level is normal but the system pressure is insufficient. How to solve the problem?
A: ①Check the connecting belt of the hydraulic pump (located between the engine and hydraulic pump). If the belt is slipping or broken, replace it with a B-type, 1200 mm belt；②Check the valve core of hydraulic valve group (located beside the hydraulic oil tank). If it gets stuck, clean it with diesel and reinstall it；③Restart the equipment and run it for five minutes without load. The pressure should be restored to 18-20 MPa.
Q2: Aggregate will accumulate during the 3.5m-wide paving process. How can I adjust it?
A: ①Increase the rotation speed of the spiral distributor from 120 r/min to 140 r/min (adjust using the knob on the right side of the driver’s cab);②Reduce the paving speed of road asphalt paver RP 355 from 4 meters per minute to 3 meters per minute; ③Remove any aggregate at the inlet of the distributor to ensure smooth feeding. Within five minutes after adjustment, the accumulation should be alleviated.
Q3: Electrical alarms often occur in the rainy season. What was I supposed to do?
A: ①Open the electrical box (located on the side of the fuselage) and replace the desiccant bag (part number: XGRP-355-001);②Use dry compressed air (0.4 MPa) to blow dry the inside of the electrical box to remove water;③Moisture-proof agent shall be placed in the electrical box to eliminate the alarm phenomenon.
Q4: Can the RP 355 pave fine-grained asphalt (< 20 mm) Do I need to make some adjustments?
A: Yes, the RP 355 can be used to pave fine-grained asphalt. Just follow the two steps.①Reduce the rotational speed of the auger to 100 rpm;②Turn off the vibration system (use the “vibration switch” on the control panel) and adopt a static pressure mode to avoid crushing fine bone materials and meet the requirements of fine pavement of community roads.
Conclusion
RP 355 small road asphalt paver redefines efficiency and accuracy in the field of road machinery. Its compact size, advanced technology and cost-effective operation make it the first choice for contractors around the world. Whether you are upgrading rural roads, transforming urban spaces or dealing with professional projects, the RP 355 can provide you with the performance and reliability you need for success.
