Is the RP903 asphalt paver the right choice for your road construction projects?

Q: What should I do if the hydraulic system does not move after starting the equipment in a low temperature environment?

① Check whether the hydraulic oil preheating system is turned on (it needs to be preheated above 20℃). If not, turn on the preheat switch and wait for 30 minutes; ② Check the oil level of the hydraulic tank (it needs to be higher than 2/3 of the scale). If it is insufficient, supplement the special L-HM 46 hydraulic oil of XCMG; ③ Check whether the suction filter of hydraulic pump is blocked (low temperatures can easily lead to impurity accumulation). If it is blocked, please replace the filter (it is recommended to replace it every 500 hours).

Q: How to diagnose the waveform on the pavement during paving?

① Check whether the laying speed is stable (it needs to be kept within 0.1 m/min. If the fluctuation is too great, adjust the speed controller); ② Check whether the leveling system (laser receiver of paver is blocked or not. If it is blocked, clean the lens and recalibrate it.); ③ Check the speed of the cloth auger (which needs to match the asphalt paving speed). If it is abnormal, adjust the frequency of the screw conveyor drive motor.

Q: What should I do if the temperature of the screed is uneven (local temperature difference > 10℃) after heating?

① Check whether the heating pipe in the corresponding area is damaged (measure the resistance with a multimeter. Normal at 10–15 Ω. If there is any abnormality, replace the heating pipe); ② Clean the carbon deposits on the bottom plate of the screed (clean it with a special scraper to avoid affecting heat conduction); ③ Check whether the temperature sensor is offset (it needs to be closely attached to the bottom plate. If offset, re-fix it).

Q: What is the reason for a sudden increase in engine fuel consumption during the operation of the equipment?

① Check whether the air filter is blocked (three-stage filtering system needs to be checked step by step. If it is blocked, please replace the filter); ② Check the atomization condition of the engine injector (if atomization is not good, disassemble and clean it. It is recommended to test the fuel injectors every 2000 hours); ③ Check whether the intelligent power regulation system is faulty (a diagnostic computer needs to be connected to calibrate the parameters. If not, restore the factory settings).

What is an asphalt paver?

An asphalt paver is a kind of road construction machinery specially used for paving asphalt on roads, bridges, parking lots and other surfaces. It distributes, shapes, and partially compacts the asphalt mixture, ensuring a uniform and smooth finish. Especially RP903, which is a high-performance model from the 3 series, is famous for its reliable quality and excellent running performance.

The Unique Advantages of the RP903 Asphalt Paver

1.Advanced Technologies for Superior Performance

RP903 adopts the most advanced technologies today, including full hydraulic drive, computer control, left-right independent drive, ultrasonic material level sensing control, electronic automatic leveling and ram compaction. These functions help to:

· Good paving Stability: ensure consistent and stable paving operations.

· Uniform Material Conveyance/Distribution: guarantees even distribution of asphalt mixture.

· High Pre-Compactness: achieves higher initial compaction, reducing the need for additional compaction work.

· Good Road Evenness: results in smoother asphalt road surfaces with minimal irregularities.

· Comfortable Operations: ergonomic control device and well-designed cab improve the comfort of operators.

· Convenient maintenance: simplifies the maintenance tasks and reduces downtime.

· Energy-Saving and Environment-Friendly: operates efficiently, minimizing energy consumption and environmental impact.(Source:https://zj.lmjx.net/tanpuji/xcmg/rp903/param/)

2.High quality Components improve reliability

RP903 uses imported products in its key supporting components, ensuring the highest level of manufacturing quality and reliability among similar imported products. This makes it very suitable for paving asphalt concrete materials on roads, with high accuracy and durability.

3.Multifunctional Applications

RP903 is suitable for paving various grades of highway pavement, and it is a multifunctional choice for different road construction projects. Its ability to handle all kinds of paving widths and thicknesses increases its flexibility.

Major application occasions

1. Municipal road building

RP903 is widely used in municipal road construction, including urban branch roads, residential roads and municipal pipeline roads. Its flexible turning capability (minimum turning radius of 5.2 m) and narrow paving width (minimum of 2.5 m) make it ideal for these applications.

2. Rural road transformation

In rural road reconstruction projects, such as the “every village has a hardened road” plan, the lightweight design (with a total mass of 26 tons) and low-temperature start-up performance (-30℃) of RP903 make it a precious asset. It can easily pass through narrow country roads and operate effectively in cold weather.

3. Road construction of industrial park/factory

For the roads in industrial parks, logistics parks and large factories, the RP 903 can provide fast road construction capacity (average daily operation efficiency ≥ 1.2 km) and low noise operation (construction noise ≤ 78 dB), which can meet the environmental protection requirements of these areas.
